A High-speed Profile Measurement System for Scroll Compressors

Abstract

Profile measurement of a scroll compressor is important for improving compression efficiency. This paper describes the height profile measurement of a scroll compressor in the manufacturing line using a prototype measurement system. A commercial CMM is also employed for comparison. The measurement repeatability of the height profile by the prototype measurement system is under 1 μm, which satisfy the requirements from the manufacturing line. Through compensation of the tilt component, result of the prototype measurement system is in a good corresponding with that of the commercial CMM.
