on-machine measuring - Opis:
- The paper describes control systems for measuring of complex workpieces machined on numerically controlled machine tools. The area is called "on-machine measurement" (OMM) and means measuring of workpieces still placed in the working space of the NC machine immediately after the NC machining operation. Measuring is performed by a touch probe inserted into the machine spindle and the movements of the probe are programmed to touch the workpiece in pre-selected points of machined surface. This makes it possible to compare the measured points with corresponding points of the CAD model and thus evaluate deviations in the normal direction between the ideal and real surfaces. In the RCMT - Research Center of Manufacturing Technology in Prague, the research of on-machine measurement methods has been performed with the aim to apply this technology for measuring of very precise and complex workpieces, produced on five-axis milling machines. Different types of control systems for three-axis, five-axis and "three and two" axis on-machine measurements have been analysed, verified and tested. The task has been solved as a part of the HARDPRECISION European project with the aim to verify possibilities in replacing application of conventional coordinate measuring machines (CMM) by on-machine measurements methods even for very complex parts with hardly accessible measured surfaces.
