CONTROLLING DEVICE FOR DRIVING HOBBING MACHINE

摘要

PURPOSE:To obtain automatically the synchronization of the driving between a hob and a table in the device by the input of the simple numerical information by an operator. CONSTITUTION:The unit moving data based on the moving speed data of a hob axis is set in a hob axis control circuit 5. The unit revolution data based on the revolution speed of a table axis is set in a table axis-control circuit 8. They are respectively transferred to output-control circuit 9, 10, and the hob axis and the table axis is driven at predetermined speed. This driving for the hob axis is continued until the contents of the command value-register of the hob axis becomes zero. The driving for the table axis is also continued in the same way until the contents of the command value-register of the table axis is restored to zero. Thus the cutting for a objective gear may be achieved.
