    摘要: A method for a machine tool to detect contact between a grindstone and a workpiece includes controlling at least one actuator to move a tool holder in a movement direction relative to a workpiece holder configured to hold the workpiece. The tool holder is configured to hold the grindstone in a manner in which the grindstone is rotatable about a tool rotation axis. The method also includes controlling a motor to make one holder selected from the tool holder and the workpiece holder stationary in a direction along a control axis crossing the tool rotation axis and crossing the movement direction. The motor is different from the at least one actuator and configured to move the one holder along the control axis. The method also includes detecting the contact between the grindstone and the workpiece based on a change in a control value of the motor.
