In the dual PC numerical control system, the CNC machining program is programmed according to the machined parts, and the user can modify it at any time. The main task of this module is to compile the NC machining program and calculate the tool radius compensation at the same time. In this way, it can be converted into a corresponding action of the numerical control actuator, and finally a qualified product is processed.
CNC machining programs are generally in the form of source code, that is, stored in ASCII format, the purpose of which is to facilitate programming.
The compiler first misidentifies the NC machining program, and the recognition types include syntax, G code instructions, and misrecognition of irregular characters. If there is an error, the error line number and the cause of the error should be indicated. The subsequent conversion work is performed only if the NC code is accurate.
The key technology is the design of this module, construct a data structure stored optimum code, calls for an interpolation program loop. Generally, both structural arrays and structural chains are used. If the structure array mode is adopted, in order to satisfy the maximum file length, the memory length will be a waste when the file length is short.
Thus, the best use of linked list structure, the structure having front and rear pointers. The dynamic application memory requirements of each code, and if not, then deleted dynamically, so as to achieve an optimal design.
The control system needs to be sealed cabinet, all the control signals of industrial control using optical isolation, to avoid signal interference. The system can display all Chinese, full screen editor, NC code syntax errors automatically detects errors in real time and various operation Chinese prompt, simple, easy to process the surface of various shaped stone and the like.
