The invention relates to software control n can be used in the automation of production processes, for example, for controlling machine tools.

A device for numerical control comprising a program setting unit, a memory unit, an arithmetic unit, a control unit and a logic unit 1 is known.

A disadvantage of this device is its narrow functionality.

It is also known a device for numerical control, consisting of a register block, a program setting block, a control block, and a storage block of program algorithms 2.

The disadvantages of this device are its complexity and narrow scope.

The closest technical solution to the invention is a device for numerical control of machine tools containing a computing logic unit, the first input of which is connected to the output of the program setting block, the second input to the output

the program correction block, the third input to the output of the control unit of the operation, the fourth input to the output of the operational memory unit, the fifth input to the output of the operational mechanism, the sixth input of the logic block, the calculations connected to the first output of the algorithm memory unit, the first output logical computing unit connected to the switch, the second output - to the input of the block of actuators, the third

10 output - with the first input of the control unit of operations, the fourth input - with the first input of the RAM block, fifth output of the logical block of calculations - with the first input of the memory block of algorithms, the second input

15 of which is connected to the second output of the operation control unit, the third output of which is connected to the second input of the RAM block, the third input of the algorithm memory block is connected to the first output of the switch 20, the second output of the algorithm memory block is connected to the second input of the operation control block , the third exit is to the input of the program task block, and the fourth exit.

the memory block of the algorithms is connected to the input of the program correction block 3.

The device is designed to operate in the continuous sequential processing mode of the program, and switching from one mode to some other mode is not sufficiently operational, which reduces the average performance of machines equipped with such devices, as in a number of cases, especially when debugging new programs for complex details it is necessary to be able to implement special modes of program processing, such as while firewood is working out a program with pauses between working off frames to perform editing operations To program in a dialogue mode, working out one or several frames by context or number, reworking program sections, element by element execution of automatic command by operator commands, working out only the technological information contained in the program without moving along the axes, working out only the geometric information contained in the program without issuing technological commands, etc. Moreover, the mode change should be carried out promptly and in an arbitrary sequence. Thus, the disadvantage of this device is its narrow scope.

The purpose of the invention is to expand the field of application of the device.

The goal is achieved by the fact that the device contains a program indication unit, a dialogue console and a mode control unit, whose input is connected to the second output, and an output to the second input of the switch, the output of the dialogue console is connected to the seventh logical unit of the logic calculation, the sixth output of which is connected to the input of the program indication unit.

The drawing shows a functional block diagram of the device.

The device for numerical control of machine tools contains a program setting unit 1, a program correction unit 2, a logic unit 3 calculations, a memory unit 4, an algorithm memory unit 5, an operation control unit 6, a switch 7, a mode control unit 8, a console 9 dialogue, block 10 display program and block J1 actuators.

The device works as follows.

The program setting unit 1, via the logic unit 3 of calculations, transfers the control program to the operational memory unit 4. Algorithm memory block 5 stores in its permanent memory all control algorithms for numerical program control, such as

such as interpolating, calculating equidistants, entering software correctors, unpacking control program frames, controlling input and output of a control program, acceleration and deceleration, searching, entering, deleting and replacing frames and symbols of the edited department program (2 technological information from geometric, and also standard operators of issuing sequences of signals to the control unit, which generates and transmits to the machine the technological command codes, signals for movement of the working bodies, and also receives answers from the machine about vsholnenii teams.

From the command part of the console 9 daaloga, from the operator, into a logical block 3. The calculations receive signals about the installation of one of the listed modes, and then these signals go to the mode control block 8. The block 8 of the modes forms the necessary features for the operation of the block 9 of the dispatcher. Based on the analysis of these features, as well as taking into account the current results of the computation process performed in logic block 3 of calculations, dispatcher block 9 generates instructions for block 5 of the algorithm memory defining the set of control algorithms used in this mode and the order of their inclusion to work.

When the microcommands stored in the block 5 memory are included in the required order, they are decrypted and, affecting the logic block 3, determine the sequence and nature of its calls to the block 4 of the RAM and to the console 9 of the dialogue. The sets of signals entered by the operator from the information part of the dialogue box 9 are processed by the logic block 3 of the calculations, and the results are recorded in the block 4 of the RAM. The response signals are entered into the program display unit 10. From the dialogue console 9, actions such as searching for the desired frame of the control program by its number, or by the context specified by its alphanumeric content, deleting or replacing the found frame, or entering a new frame next to that found, searching for indidation, deleting , replacing the new alphanumeric address, within the frame of the program; set, enter, read, replace and reset numeric program correctors; setting the required mode of operation; installation of the required solution of input (output of the control program) through an autonomous photo reader, or from a computer of the highest rank; setting m}) of the frame (by number or context) on the output of the system in which it is, correspondingly)
