On-machine non-contact dimension-measurement system with laser displacement sensor for vane-tip machining of RFQs

We have developed a new on-machine non-contact dimension-measurement system using a laser displacement sensor (LDS) for machining the vane tips of RFQs. The LDS was attached to a milling machine, and the dimensions of a test piece (TP) with a modulated vane tip were measured to evaluate the performance of the system. A longitudinal profile was measured with the LDS and it was compared with the profile measured with a coordinate measuring machine (CMM). A transverse profile was also measured. The required accuracy of dimension measurement was achieved using our system.
