Use of Air Beam for In-Process Optical Measurement in Precision Machining

Abstract:

In order to allow optical signals to reach the workpiece surface to realize in-process optical measurement through an opaque coolant, a locally transparent region generated by use of an air beam is examined to allow better understanding of the fluid assisted in-process optical measurement approach. With the air beam used, the problems associated with the diluting effect on coolant concentration and the measurement error due to the optical transmittance through multiple media can be avoided. The working principle and the experimental results for testing the proposed method are presented and discussed.
