SYNCHRONIZING SYSTEM FOR TOOL POST OF NUMERICAL CONTROLLER

摘要

PURPOSE:To assure the synchronism for the starting of a block of a working program by programming an instruction code at an area where the starting synchronism is reguired. CONSTITUTION:The working programs of tapes 1A and 1B are read, and numeric calculations are performed. then a machine tool containing plural tool posts is numerically controlled via a control circuit 6 and a programmable controller 13. The circuit 6 contains controllers 6a and 6B for the 1st and 2nd tool posts. These tool posts are controlled by the working programs corresponding to the tapes 1A and 1B. A synchronizing controller 6C is provided to secure the synchronism between both controllers. The synchronizing commands (!) are supplied to the circuit 6. In this case, the command (!) consisting of a character is put into each working program. Thus the controllers 6A and 6B carry out the working programs respectively.
