Experimental Investigation on Varying Speed Control of Harmonic in Centreless Grinding
According to the quasi-dynamics harmonic generation theory, the varying speed control method for the harmonic of the rolling bearing ring raceway surface is studied to solve the optimal control problem about the harmonic distribution and the roundness error. The experiments on the constant speed grinding and the varying speed grinding are conducted to view the grinding results. Based on the vibration characteristics of the supported centreless grinding system, the impact of the rotational speed of the ring and the electromagnetic centreless fixture layout parameters on the harmonic distribution are considered for the optimum grinding plan. And the optimum varying speed control experiment is done and the obvious result is obtained, revealing the intrinsic character of the quasi-dynamics harmonic generation theory and supplying a foundation for the quality control of the supported centreless grinding system.
