CNC = Computer numerical control (CNC control) Entering data processing program is read only once from the media and entered into the program memory. Also, you can enter a full treatment program directly on the machine with CNC keyboard (guild programming). Processing program can be called from the memory of an unlimited number of times. Obrabotka data input information is processed by a microcomputer that usually consists of one or more microprocessors and various memory elements. Input and output program performs input and output. Parity, identifying code and dividing by the geometric and technological data carries program decryption. Interpolation (calculation of intermediate points) in the processing of the circles and diagonal lines is carried out by a special program of interpolation.
The control program for program memory puts a frame on performance indicates routines and conducts programs directory processing, which at this time are in the program memory. System tracking tracking system is a programmable unit, which is connected to the microprocessor. This makes it possible to programmatically processing the control signals that come from the machine, which allows, for example, find out the cause and stop the sources of error. Program editing Editing called correction, modification and optimization of embedded in a computer memory management software (PC). It is possible to insert, replace or modify the program blocks (frames). In addition, parts of programs are displayed on the screen. CNC-type CNC can not imagine the tool path graphically.
