Workpiece rotational speed controller for cam grinding machine |
摘要 |
A workpiece rotational speed controller having a pulse counter responsive to a pulse signal generated from a pulse generator for indicating the actual angular position of a cam shaft during grinding on a cam grinding machine and a comparator for comparing a count value of the counter with any one of set values which are set in a plurality of digital switches to designate respective speed change positions. A region detection counter is further provided, which counts any coincidence signal from the comparator so as to enable a command voltage generator to apply to a servomotor for cam shaft drive a command voltage that changes step by step in correspondence to the region detection counter output. This counter output is also applied to a gate circuit, which is thus enabled to selectively apply the set values of the digital switches to the comparator.
