Title:
MACHINE TOOL, METHOD FOR DETECTING CONTACT BETWEEN WHETSTONE AND WORKPIECE BY MEANS OF MACHINE TOOL, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/095339
Kind Code:
A1
Abstract:
This method for detecting contact between a whetstone and a workpiece by means of a machine tool involves controlling at least one actuator so as to cause a tool retainer, which retains a whetstone so as to be rotatable about the tool rotational axis, to relatively move in the movement direction relative to a workpiece retainer which retains a workpiece. This method also involves controlling a motor which is different from said at least one actuator and which is capable of causing either the tool retainer or the workpiece retainer to move along a control axis that intersects with both the tool rotational axis and the movement direction such that either one of the retainers stands still in a direction along the control axis. This method further involves detecting contact between the whetstone and the workpiece in accordance with a change in the control value of the motor.
