Measuring device for machine tool for detecting erroneous formations and/or air passages of contour of workpiece, has probe designed such that probe inter-leaves mark on workpiece during impinging on erroneous formations and/or passages

摘要

The device has a mechanical probe (1) for fixing machine tools in a tool holder (2), where the probe is deformable and has a predetermined breaking point (3). The mechanical probe is designed such that the probe inter-leaves a mark on a workpiece during impinging on erroneous formations and/or air passages at a contact point. The probe is partially made of brittle material, where deformation of the mechanical probe is monitored by a tool breakage detection. The probe bends during impinging on the erroneous formations and/or air passages. An independent claim is also included for a method for detecting erroneous formations and/or air passages of a contour of a workpiece.
