摘要： PROBLEM TO BE SOLVED: To provide a grinding apparatus accurately detecting a contact between a grinding wheel and a workpiece without using a sensor such as a force sensor.
SOLUTION: Using an inprocess gauge (S1) from before contact, inprocess gauge values are collected (S2). This inprocess gauge signal is subjected to an LPF processing (S3), and the amount of amplitude of the inprocess gauge signal is compared with a threshold value (S4). The amplitude of the inprocess signal is initially large and then gradually decreased. At a certain point of time, it becomes smaller than the threshold value, thereby determining that the grinding wheel is in contact with the workpiece (S5).
