Abstract
A machining operation end position detecting unit detects the end position for a machining operation at a (k-1)-th step. A machining operation starting position detecting unit detects the starting position for the machining operation at a k-th step. A machining position comparison unit compares them with each other. If the difference between them is less than a predetermined value, a signal is output to a machining condition changing unit and a control valve. As a result, the machining condition is changed, and a powdered substance is fed into a working fluid.
