Process and device for controlling correct seating of a part on a surface

摘要

The method involves monitoring whether an object is correctly arranged on a supporting surface in a machine tool and/or clamped by a device with first and second clamping arrangements using a line system carrying a medium and subject to pressure ending in the support surface and/or in the first clamping arrangement. The end opening of the line system is covered by the object and/or the second clamping arrangement, the pressure in the line system is reduced at a choke point, the pressure difference before and after the choke point is determined and evaluated for support control or clamping control. The cooling/lubricating liquid, an air-coolant mixture or the air-coolant flushing medium of a machine tool is used as the medium. Independent claims are also included for the following: (A) a device for object support control for a machine tool (B) and a machine tool, especially a cutting tool, with an inventive device.
