Abstract
PURPOSE: To provide a crankshaft mirror control device in which inconveniences as to be caused by the use of NC device are eliminated, and which is capable of cutting a crankshaft into perfect circular form, by controlling the amount of cutter feed.
CONSTITUTION: When cutting start instruction S is memorized in flip-flop 16, signal Open is given to gate 11, and pulses from pulse generator 5 are given to NO.1 decimal counter 6a, pulse distribution computer 12 and X-axis servo amplifier 3. The signal of counter 6a is sent, via NO.2 counter 6b, to counter 13, which detects and displays the position of the rotational angle of X-axis. By this, the amount of Y-axis feed and the out-of-roundness compensation memorized in the addresses of the position of the corresponding rotational angle in No.1 and No.2 memories 14 and 15 are read out and are sent to adder 17, and thereby the amount of true feed is calculated. X-axis and Y-axis are controlled in synchronization by counter 12
