Turners competition.

Several experienced workers and a young graduate of vocational school.

The workers received drawings of the same part.

Experienced craftsmen work at the machines.

A young worker will process the part on an automated machine.

Working on such a machine requires a pre-compiled program.

A young worker makes a program.

The program is entered into the machine.

When the worker finished working on an ordinary machine, the automated machine produced 10 parts.

The predecessors of this machine are CNC machines.

This machine is controlled by a computer with a program printed on the punched tape.

Programmers who create a program for such a machine.

The program created for the machine cannot be changed or supplemented by a person at the machine if a quick operative intervention of the turner is required, for example, when changing the configuration of a part or its processing technology.

The system of CNC machines does not allow you to do this.

Cartoon explaining the principle of operation of the CNC.

Creation of machines with a control system that can independently determine the processing technology.

Previously, only dimensional information was required from the worker.

Such possibilities are presented by a computer reduced by hundreds of times.

This is a universal microcomputer.

Each such computer can work in one area.

Previously, it must be trained, i.e. provided with a certain set of instructions.

The class of training turners in vocational schools.

A cartoon explaining the compilation of programs for the operation of an automated machine.

Block diagram of the machine programming.

The internal structure of the machine with operational program control.

An employee sets up the machine.

Electric drives of the machine.

The speed box of the machine.

Operator's console.

With the help of the remote control, the processing modes of the parts are introduced.

In the first mode, the tool is moved by simply rotating the handwheel.

These steps are necessary to install the tool.

The direction of movement is set by pressing the keys on the remote control.

Manual processing key.

The third key is used to work in automatic mode.

In this case, the machine works according to the instructions of the program entered into it.

The processing program is compiled by a worker.

Drawing of a part with dimensions and geometric shapes.

The drawing suggests the processing technology of the part, the trajectory of the tool.

The trajectory is set by reference points on the contour of the part.

In addition, commands must be given to the machine's executive bodies.

Each such command contains a letter address and a numeric code.

Alternating frames with codes and movements corresponding to this code.

A sequence of commands with a transcript of operations.

Some commands specify a single action, some a whole cycle.

Such standard cycles are stored in the machine memory.

To remove the allowance, it is enough to write down the G77 command, specify the final diameter, processing length, cutting depth.

The system itself will calculate the number of penetrations and the trajectory of movement for each passage.

Chamfering cycle, cone turning and other operations.

Cycle records are interspersed with frames of operations on the machine.

Entering the control program into the machine memory.

If the operations are required in the future, they are sent to the machine memory.

An external memory cassette where you can download the necessary programs, as well as use these programs on other machines.

If it is necessary to find the necessary programs in memory and transfer them to RAM.

After entering, you can check the program by checking the indicator readings with the records.

Correction of errors.

There is a possibility of drawing up a program based on a sample.

Before starting the program, you need to enter the value of the tool departure.

You can start work only with the machine casing closed.

Cartoon explaining the machine control system.

Frames with various automated machines.

The tasks of loading and unloading the machine are often assigned to the robot.

The machine, robot and conveyor operate synchronously, obeying the commands of their control systems.

The programmer compiles a program for the operating system.

Quality control is carried out during the operation of the system, if there are violations, the system introduces adjustments.
