Paper Abstract

Researches are made to find out the active tracing measurement strategy of crankshaft roundness error during noncircular grinding process. This paper makes a detailed study on the tracing motion equations of the measurement system. Aiming at the request of three sensors' linear dependence in frequency-domain analysis, this paper also describes the constraint condition of uniform sampling. For improve the in-situ measurement precision, the three-sensor tracing principle of roundness error separation (TTPRES) is proposed under motion stage. Furthermore, the method for avoiding harmonic suppression by adjusting the installation angles of three sensors is discussed. Finally, the data processed by error separating are calculated using Least Square Method (LSM), and contrasted the compute result with the measurement result of Roundness Measuring Instrument. The experiment proves the validity of in-situ tracing measurement strategy of crankshaft roundness error during noncircular grinding process.
