To summarize, we can say that the number of products that can be made on a CNC milling machine is huge. All you need is equipment, a desire to work and a little experience.

Many beginning furniture makers are faced with the need to create facades based on MDF boards. Moreover, the requirements for products in conditions of high competition are quite high.

Products must be of high quality, meet modern standards and trends, and in addition, in order to have a stable flow of customers, the entrepreneur must fulfill their orders as quickly as possible. It is possible to get the job done efficiently and quickly only if you use technologically advanced tools for the job. In this case, these are CNC machines. We will explain below what they are and how they work.

What does this abbreviation mean?

The decoding of this concept is as follows: Numerical Control. That is, a machine tool operating on numerical control is capable of performing certain actions that are assigned to it using a special program. The operating parameters of the machine are set using numbers and mathematical formulas, after which it performs the work according to the requirements specified by the program. The program can set parameters such as:

power;
speed of work;
acceleration;
rotation and much more.

Features of CNC machines

The technique for creating furniture parts using a modern device of this type includes several stages of work:

All mechanical actions that the equipment performs are the embodiment of a sequence that is written in the control program.

Modern CNC machines are complex electromechanical devices and require skilled use. The main operation of the machine is carried out by two people:

service technician;
CNC machine operator.

The adjuster is entrusted with a more complex array of work; he performs adjustments and readjustments of the device, and the operator must monitor the work process and carry out easy adjustments.

Actions of the CNC machine operator and operator

Stages of the adjuster's work look like this:

selecting a cutting tool according to the map, checking its integrity and sharpening;
selection according to the adjustment map of given sizes;
installation of the cutting tool and chuck, checking the reliability of the workpiece fastening;
setting the switch to the “From the machine” position;
checking the working system at idle;
introduction of punched tape, which is carried out after checking the tape drive mechanism;
checking the correctness of the specified program for the console and CNC machine and the light signaling system;
fastening the workpiece into the chuck and setting the switch to the “According to program” mode;
processing of the first workpiece;
measuring the finished part, making corrections using special corrector switches;
processing the part in the “According to program” mode a second time;
taking measurements;
moving the mode switch to the “Automatic” position.

At this point, the setup process is completed and the CNC machine operator begins work. He should do the following:

change oils;
clean the work area;
lubricate cartridges;
check the machine for pneumatics and hydraulics;
check the exact parameters of the equipment.

Before starting work, the operator of the CNC machine must check its operation using a special test program, and he should also make sure that the lubricating fluid is supplied and that there is oil in the hydraulic system and limiting stops.

In addition, he must check how securely the fastening of all devices and tools is, as well as how well the furniture piece corresponds to the specified technological process machine What follows take measurements on the subject possible deviations on the accuracy of zero setting on the device and other parameters.

And only after these manipulations can you turn on the CNC machine itself:

the workpiece is installed and secured;
then the work program is introduced;
punched paper tape and magnetic tape are loaded into the reading device;
click “Start”;
after the first part is processed, it is measured to ensure compliance with the previously specified model.

Areas of application of CNC machines

CNC-based machines are used in various service and manufacturing industries:

for processing wood and wood panels;
for plastic processing;
stones;
complex metal products, including jewelry.

CNC devices have a number of such functions, How:

milling;
drilling;
engraving;
sawing;
laser cutting.

Some models of CNC machines have the ability to combine simultaneously different types processing of materials, then they are called CNC machining centers.

Advantages of CNC machines

The use of CNC-based machines and machining centers in production allows for timely completion of work that would be impossible without their use. For example, when producing furniture facades from MDF in this way, you can complex relief decors, which are simply impossible to do manually. Thus, thanks to special graphic design programs, you can realize the most daring design solutions.

In addition, mass production of MDF facades using large-format CNC machines is possible without the need to pre-cut the boards and allows for a full cycle of processing, which significantly saves time and labor.

The price of CNC-based equipment is such that you need to think carefully before purchasing it whether it will be economically profitable specifically for your production facilities. If you have a stable flow of clients, and they are willing to pay for original design solutions, then you can safely invest in such equipment.

The peculiarity of CNC-based machines is their reliability and the ability to operate uninterruptedly for many years. But when working with them, you must follow all safety rules, and also select only qualified operators and adjusters. Poor quality work by personnel can cause the device to fail ahead of schedule.

Most production structures are getting rid of conventional machines and purchasing advanced equipment. Their main motive is the highest processing precision. And having completed the configuration new technology, they begin to look for specialists capable of working on it.

It was with pleasant surprise that I read an ad online inviting a specialist for a complex deal for bitcoins. And this is proof that the profession is in demand and prestigious. The work of a competent specialist is highly valued.

Gone are the days when a craftsman (turner or milling machine) had to configure the equipment himself and monitor the operation of the machine park. Now that all processes are automated, working on a CNC machine requires much less effort than in the past, but the requirements for skill levels are increasing.

Have knowledge of CNC

Milling, drilling and lathes with numerical control (CNC) belong to equipment that can be used to perform mechanical processing of any material (we are talking about plastic, graphite, aluminum, copper, cast iron and steel, wood) with special tools - cutters, drills and incisors. An experienced operator, as well as a service technician, knows that the material of the cutting part of the tool has a hardness and strength that is designed to be higher than that of the workpiece being processed. They select an alloy from hard and high-speed alloys; they use diamond and a mineral-ceramic component.

A qualified specialist knows the shapes and types of instruments, their scope of use, and the rules for caring for them. In addition to horizontal and vertical types machines, common and universal. On them, complex parts can be processed at the desired angle, using different tools.

Rotating quickly, they are able to grind workpieces, cut them, cut material, drill holes, and engrave. And all processes are controlled by the CNC block program.

Movements along the axes ( we're talking about about the portal and spindle) are provided by three microstepping motors. Together with the tool, they make up the mechanical unit of the device. But production operations are controlled by an electronic unit. With the help software graphic files are processed, which become vector images and are converted into G-code.

Range of skills working on programmable equipment

To produce a part using a CNC machine, you must be able to:

build it using a graphic editor (AutoCad, Corel Draw);
install the program in the machine’s RAM or RAM;
determine the mode and control parameters of microstepping motors that are adequate to the technological task and the type of materials that need to be processed;
visually monitor the progress of each technological operation on the panel, where the display is visible current information about the operation of the equipment.

Operators are not required to perform particularly complex actions in the process of servicing CNC machines, and the use of programmable equipment simultaneously solves several tasks:

the level of productive labor increases;
Excellent quality and precision processing is ensured;
the solution to problems with production culture and labor safety is improved.

ATTENTION! A control program is created for at least two cutters. With the help of the first, rough work is performed on the workpiece: and the second is used for finishing processing.

Learn – master a skill

Agree that turners and millers are not born, they are made. And this profession must be learned. Where? How long? Advertising in social networks replete with headlines like: “We’ll teach you how to operate a CNC in 5 minutes!”, “Learn how to operate a machine in 2 weeks!” Such statements are nothing more than bravado. We don’t take 5 minutes into account at all. In 2 weeks you can have time to listen to a certain compressed theoretical course of study.

But in order to become a specialist, moreover, competent and responsible, worthy of taking a position that is highly paid, you also need practice.

The most reliable option for mastering a profession is to study at a specialized educational institution - college. There they teach according to a program where there is room for both theory and practice (in certain proportions). The right approach to learning and consists in combining theory with practice. It is good to learn theory if at home, in the educational institution where a person receives an education, there is something to try to work on independently.

An excellent option if you are invited to work on a CNC machine with training in the profession. It is worth the attention of the job seeker, since his training will take place directly on the job. There, managers are directly interested in quickly preparing highly qualified workers.

What about studying online?

Today this is quite real. We are ready to teach you how to operate a CNC machine using some online resources. In particular, remote courses via Skype online have become very popular. And, in general, this is not bad:

listen to a competent presentation of theoretical foundations;
see how this technique works;
draw the attention of teachers to certain nuances.

But until a person approaches the machine himself, touches everything with his own hands and tries to perform all the recommended operations, it is difficult to consider that he has learned something.

What is good about such courses is the reusable exercises on (control programs); acquiring skills in creating vector images and using the capabilities of ArtCam, StreameLine, Mach 3 and other programs.

It would be a good idea to watch a video (there are quite a few of them on the Internet), where they will theoretically teach how to maintain and set up such machines. And then acquire a set of necessary practical skills.

Distribution of responsibilities

Considering the fact that today programmable machines are complex electromechanical devices, coordinated maintenance is carried out by two people: (he is entrusted with complex operations related to the setup and readjustment of the device), and the operator must monitor the progress of the process and maintain the machine.

The adjuster, while performing his duties, is engaged in:

selection of tools, checking their sharpness; introduction of the provided technological map sizes;
installation of tools; checking how reliable the fastenings, the tape drive mechanism and the entire system are when operating in idle mode;
introduction of punched tapes, analysis of the correctness of programs;
fixing workpieces in the chuck, starting the “According to program” mode.

Having processed the workpiece and measured the part made, the technician makes adjustments, and another workpiece is processed in the same way. If there are no discrepancies in size, the “Automatic” mode is entered and then the operator performs his functions. It does:

changing oil and grease in cartridges;
adjustment of pneumatic and hydraulic components of equipment and precise parameters;
cleaning the area leaving the work area;
performance testing.

He must also make sure that lubricant is supplied to the hydraulic system and other components.

Be ready for a new level of demands

The intensive development of microprocessor technology has contributed to the fact that now, every 3-5 years, the hardware of CNC devices and their operation undergoes a significant update.

Today, robotic production is becoming more and more common in the mechanical engineering industry. The concept called “unmanned production” has become more realistic. We are talking about complete robotization of enterprises in the mechanical engineering sector. Ideally, we will have fully automatic production, in which no human is involved.

The appearance of robots, predicted by science fiction writer Isaac Asimov, has now been embodied in metal. And this gave rise to a whole series of problems. In all seriousness, behind the scenes of the government South Korea, there is a debate about editing the text of the “Charter of Ethical Standards for Robots.”

But this is a distant prospect. And now for many young people it is realistic to gain a knowledge base for working with a CNC machine. This is the path to one of the most sought-after professions of our time.

Equipment with numerical control attracts all people who are interested in making high-quality and necessary products with their own hands.

They deal with a variety of machines from the turning and milling groups. In particular, with revolving, as well as high-performance aggregate (for various models This type of equipment can simultaneously work within 100 tools: cutters, drills, cutters).

If a curved shape of the generating surface is required, the work is performed using a hydraulic support, which is controlled by CNC. Today, the CNC system can also be installed on waterjet machines. Their function is high-quality cutting of sheet material: metal, plastic, natural and artificial stone, glass.

Conclusion

Today it is prestigious to work on CNC machines, and therefore the requirements for the level of qualifications are quite high. An experienced equipment installer or operator must know and be able to do a lot in order to meet these qualification requirements and feel confident at any stage of work.

Let's consider the operation of machine tools with a CNC system according to a simplified diagram (Fig. 7.1), which includes the main blocks of CNC systems and the main elements of the kinematic diagram of the machine. The CNC system consists of information input devices, a block for storing information BZI , BI interpolation block , feed drive control unit in the form of digital-to-analog converters DAC and two servo drives along the X and V axes of the machine. Tracking drives consist of power amplifiers UM X and UM U, comparing devices US X and US Y , feedback sensors in the form of rotating transformers VT X and VT U , kinematically connected to the machine lead screws and feed motors M x and M y , which drive the machine's lead screws to rotate. As a result of the rotation of the screws, the machine table and its slider with the cutter move, the joint movement of which determines the configuration of the part being manufactured according to the programmed program.

All modern CNC devices are based on some kind of microcomputer or microprocessors (one or more), which make it possible to significantly increase the degree of automation of the machine, i.e. provide: indication of a large number of parameters on the display screen, quick diagnosis of faults and convenient editing of programs, storage of a large volume of control programs, etc.

Composition of the CNC system

All CNC devices have developed cyclic automation with a large number of inputs and outputs, as well as communication with a computer top level necessary when creating flexible production systems.

At the same time, there is a division of CNC devices according to the number of controlled coordinates, related to their purpose: for lathes, two coordinates are usually required; for conventional milling machines – three; for milling machines intended for volumetric processing - five; for multi-operational machines - from four to eight. Currently, CNC devices have been created for 10–12 coordinates to control PMG. The number of coordinates has a very significant effect on the design and cost of the CNC device.

The functional diagram of a typical universal CNC system (Fig. 7.2) consists of two main devices: a numerical program control device, structurally designed in the form of a separate cabinet or console, and actuators with drives and feedback sensors located on the machine. The main blocks of the CNC system are described below.

Rice. 7.1. Simplified diagram of a CNC machine

Information input device enters numerical information from the software.

Block for storing read information. In addition to storing the input information, this block monitors it and generates an appropriate signal at the moment an error is detected. This block, as a rule, has the ability to receive information from a top-level computer, which is necessary when combining machines into a GPS.

Control and display panel serves to connect the human operator with the CNC system. Using this remote control, the system is started and stopped, operating modes are switched from automatic to manual, etc., as well as the feed speed and tool sizes are adjusted and the initial position of the tool is changed along all or some coordinates. This remote control contains a light alarm and a digital indication of the system status.

In modern CNCs, indication is usually carried out using a built-in display, which allows you to display significantly larger number parameters, as well as testing programs directly on the machine.

Interpolation block forms a partial tool path between two or more points specified in the program. In most cases, linear and circular interpolation are used, although helical or cylindrical interpolation is sometimes used.

Feed drives, most often servo, they serve to ensure the movement of controlled elements of the machine (tables, supports, carriages, etc.) with the required speed and accuracy at a given moment. By servo drive we mean a system consisting of a motor (electric, hydraulic), a power amplifier that supplies this motor with the necessary energy, which is regulated within wide limits, a position feedback sensor used to measure the actual movement (or position) of the controlled object, and a comparing device that compares the actual position of an object with a given one and produces an error signal that goes to the input of the power amplifier, as a result of which the angular velocity of the motor shaft turns out to be proportional to the system error. During operation, this system moves the controlled object in such a way as to maintain a minimum error value. If the error for any reason exceeds a predetermined acceptable limit, the CNC system is automatically turned off using special protection devices.

Feed drive control units serve to convert the information received from the output of the interpolator into a form suitable for controlling feed drives, so that when each pulse arrives, the controlled object moves a certain distance, called the pulse value, which is usually 0.01 or 0.001 mm. Depending on the type of drives (closed or open, phase or amplitude) used on machine tools, control units differ significantly.

In open-loop drives using stepper motors, the control units are special ring commutators, the output of which includes powerful amplifiers that power the windings of the stepper motors, which serve to cyclically switch the stepper motor windings, which causes its rotor to rotate. In closed-loop phase-type drives that use feedback sensors in the form of rotating transformers (VT) or inductosyns in the phase shifter mode, the control units are pulse converters into the AC phase and phase discriminators that compare the phase of the signal at the output of the phase converter with the phase of the feedback sensor and output a difference error signal to the drive power amplifier.

The same block usually contains amplifiers for powering feedback sensors, as well as protection devices that turn off the drives when the permissible tracking error is exceeded.

Feedback sensors DOS are measuring devices used to determine the actual position (absolute coordinate value) or movement (relative coordinate value) of a controlled object within the system step. In this case, the steps are summed up by the CNC system. The movement of the object is determined both directly using any linear measuring devices, for example, inductosyns, and indirectly, by measuring, for example, the angle of rotation of the feed motor shaft using some angular measuring device, for example, a conventional VT or resolver (accurate VT sinus - cosine type, used in computers).

In addition to inductosyns, other measuring devices are sometimes used to directly measure linear movements, for example, precision racks with multi-pole VTs, or to achieve particularly high accuracy, optical line measuring scales with corresponding pulse sensors. Typically, the same CNC device can work with different types of DOS.

Rice. 7.2. Functional diagram of the CNC system

Feed speed block provides a given feed speed, as well as acceleration and deceleration at the beginning and end of processing sections according to a given law, most often linear. The feed rate is specified either by the speed number of the corresponding series of speeds, forming a geometric progression with a denominator of the order of 1.25, or directly in millimeters per minute after 1 or even after 0.1 mm/min. In addition to operating feed rates, which are usually 5–2000 mm/min, this block, as a rule, also performs an installation movement at an increased speed, at which coordinates are set during positional processing or the tool moves from one section of the workpiece to another during contour processing. This speed in modern systems CNC speed is 10–15 m/min.

Program correction block together with the control panel, it is used to change the programmed processing parameters, i.e. feed speed and tool dimensions (length and diameter). Changing the speed of movement (usually 5–120%) comes down to manually changing the frequency of the master generator in the feed unit. Changing the length of the tool (usually from 0 to 100 mm) is reduced to changing the specified value of movement along the axis of the tool, without changing its initial position.

Technology command block designed to control the cyclic automation of the machine, including searching and changing a sufficiently large number of tools (up to 100), changing the spindle speed, clamping the guides during positioning and releasing them during movement, various locks that ensure the safety of the machine. The cyclic automation of the machine consists mainly of actuators such as starters, electromagnetic couplings, solenoids and other electromagnetic mechanisms, as well as discrete feedback elements such as limit and limit switches, current relays, pressure relays and other elements, contact or non-contact, signaling the state of the actuators organs. Often these elements with additional devices such as relays implement local cycles (for example, a cycle of searching and changing a tool), commands for execution of which are sent from a program control device. Modern CNC devices, as a rule, carry out these cycles internally, issuing signals to the actuating elements of the machine through matching and amplifying devices, which can be located both in the machine and in the CNC device. For this purpose, programmable controllers are often used in the form of a separate unit located inside or outside the CNC device.

Canned cycle block serves to facilitate programming and reduce program length during positional processing of repeating workpiece elements, for example, when drilling and boring holes, threading and other operations.

In addition to these blocks, adaptation blocks are used, which serve to increase the accuracy and productivity of processing when changing according to a random law external conditions(for example, machining allowance, hardness of the material being processed, dullness of the tool). This is explained by the fact that any CNC system is an open-loop control system, since it does not “know” the result of its work. In a CNC system with conventional feedback the workpiece is not covered by it; only the movement of the tool relative to the workpiece is specified. At the same time, the dimensional accuracy of the part is affected, for example, by tool deformation, which in conventional CNC systems can be taken into account during programming only when it is constant or changes according to a previously known law, which is not the case in practice.

Feed drives for CNC machines

Modern CNC machines use various structural designs of feed drives. A circuit with a rigid coupling of the lead screw electric motor is shown in Fig. 8.1.

Rice. 8.1. Drive diagram:

1 - electric motor; 2 – coupling; 3 − rolling screw-nut transmission; 4 - screw

A diagram with a single-stage gearbox and a gap in the gear is shown in Fig. 8.2.

A diagram using backlash-free worm and rack gears is shown in Fig. 8.3.

Rice. 8.3. Drive diagram with worm and rack gears:

1 – electric motor; 2 – worm gear; 3 - rack and pinion

As can be seen from the above diagrams, CNC machines have short kinematic circuits for feed drives, ensuring more accurate operation of the feed drives. This became possible through the use of special components and mechanisms that have their own distinctive features.

The development of technology has caused computers and other advanced technical means to be increasingly used in everyday life people as well as in industry. For example, in modern industrial enterprises you can increasingly find one that is controlled not by the operator’s hands, but by means of special computer programs and related electronic devices.

Thanks to such a control system, the operation of the machine is greatly facilitated, and is eliminated from the process of manufacturing parts. human factor, which can provide negative impact on their quality and processing accuracy.

Operating principle of milling machines

Milling equipment allows you to carry out various technological operations: cutting, drilling, calculating the distances between holes that need to be performed, as well as a number of others. The materials that can be processed on such equipment can be:

wood;
ferrous and non-ferrous metals;
ceramics;
polymer materials;
natural and artificial stone.

The workpieces are fixed on the work table, and their processing is carried out by a rotating cutter, which cuts the material.

Equipped with CNC, they are available in various designs.

Console type:

models with wide versatility;
horizontal type;
vertical type.

Non-cantilever design:

vertical;
horizontal.

The most popular and, accordingly, widespread are console-type CNC milling machines. The workpiece being processed is fixed to the console, and it is this working body that makes movements in relation to the cutting tool. The spindle of such a machine does not move; it is rigidly fixed in one position.

The non-console type is achieved due to the fact that both the worktable, which moves in two directions, and the spindle, which can change its position in the vertical plane, as well as in all other directions, can move in them.

The CNC automatically performs operations, information about which is previously recorded on one of the media. The programs that control its operation can be of several types.

Positional, which involves fixing the coordinates of the end points along which the workpiece is processed. Such programs are used to control drilling and boring machines.
Contour, controlling the trajectory of workpiece processing. They are used to control cylindrical grinding machines.
Combined, which combine the capabilities of contour and positional programs. Such programs control machines belonging to the multi-purpose category.
Multi-circuit. With their help you can control all the functionality of the machine; they are the most complex type BY. With the help of such programs, control of large-format equipment is ensured.

Milling machines equipped with CNC have a number of significant advantages:

allow you to increase processing productivity by 2–3 times;
make it possible to produce parts with high precision;
minimize the amount of manual labor, which allows reducing the number of service personnel;
reduce the time required to prepare workpieces;
minimize processing time for parts.

Types of equipment

Milling group machines equipped with CNC, depending on what material is processed on them, are divided into the following categories:

for metal work;
for processing wood blanks;
milling and engraving group.

processing centers with high functionality;
machines of a wide-universal type;
turning and milling category;
drilling and milling group.

Milling machines, controlled using special programs, can also be used to equip a home workshop, as they are easy to operate and make it possible to produce metal parts made with high accuracy of their geometric parameters.

At enterprises that produce furniture, as well as in construction companies CNC-equipped milling machines are used to process wood blanks. These machines process wood products, as well as blanks made of polymers, aluminum alloys, plywood and chipboard.

A CNC machine, which can perform engraving operations, is used for processing products made of metal, natural and artificial stone, concrete and a number of other materials. It is used to make decorative stone columns, figurines, and other products that perform a purely decorative function. Such machines for metal and a number of other materials are most often used for the production of various advertising structures.

Based on the principle of operation and their performance, milling machines equipped with CNC can be of the following categories:

characterized by small dimensions and low productivity - mini machines;
desktop type;
vertical milling type;
widescreen.

The machines that are used to equip a home workshop cannot be called professional; they are mainly used for a useful hobby. Such CNC-equipped milling machines are low-cost, so they are often equipped in workshops of various educational institutions: schools, technical schools, universities, etc.

Desktop equipment has a number of significant advantages:

low cost;
exceptional mobility;
ease of operation and design.

Such machines, despite their compactness, are capable of performing various technological operations on metal and other materials: milling, drilling, boring.

Vertical milling machines are used to process large workpieces. They use drills, cylindrical, end, shaped and end cutters as working tools. With the help of such equipment, which is mainly equipped with large production enterprises, it is possible to process both horizontal and vertical surfaces.

Large-format CNC-equipped milling machines live up to their name: they have a special working head that can be rotated in any direction. Due to their versatility, such machines are most often used to equip non-standard equipment workshops and tool areas.
