This command is mainly used for cam finishing. The program encounters the command G151 during the execution. The Z axis will oscillate with the width EW at the current position without affecting the execution of the machining program unless canceled with the G150 command.
G100: Spiral interpolation cycle format: G100 X**C**F**
Description: X, C---The absolute coordinate value of the X and C axes at the end point, F---Feeding speed G106: Parabolic interpolation format: G106 X**C**P**Q**F**
Description: X, C---The absolute coordinate value of the X and C axes at the end point, P, Q---The tangent angle of the starting point and the end point F---Feeding speed G189: Grinding wheel correction cycle format: G189 EF**EN **ER**
Description: EF---rough, fine correction selection, EN---correction times, ER---correction grinding wheel radius, correction position and other data are stored in the tool offset table, which is automatically calculated and changed during program running.
G196: Main axis speed programming format: G196 ES**
Description: ES ** --- wheel speed <br> <br> Fourth, the application summary <br> <br> by the above transformation program, we have successfully restored normal processing performance of the cam grinding machine, making more than a year of equipment downtime It is put into operation again, the machine tool runs stably and reliably, and the operation is relatively simple.
After the successful transformation of the cam grinder, we modified the German DRH2/1500 double-column vertical grinding machine with NUM1020/1040 system, modified the German SS13 program-controlled slow-feed grinding machine as the CNC grinding machine, and modified the German-made P250H program-controlled hobbing machine as the CNC hobbing machine. Has achieved good results.
The successful application of NUM system in the above equipment has fully exerted its good openness and flexibility, indicating that it has strong adaptability in the transformation of old equipment to meet the special requirements of old machine tools, and the cost performance is high.
