This paper proposes a new method to control lapping speed of the lapping machine properly, which may reduce lapping stroke and improve lapping accuracy and quality. In the beginning of lapping, the rotating acceleration of the lapping tool is controlled. It makes the acceleration increase from zero slowly. When lapping speed reaches a certain figure, inflection point of acceleration appears. Then...
The computer control technique is used to control lapping pressure on-line in this paper. In the starting period of lapping, contacting state between the workpiece surface and lapping tool surface is not ideal case. In order to reduce the impact between the workpiece and lapping tool, in starting lapping, the lapping pressure is lower, and then increases gradually until a certain higher pressure reached...
