Cam bump at the diamond wheel workpiece contact zone

To improve the roundness parts, the first blank can not have too large roundness and concentricity error. In order to ensure the final workpiece dimensional accuracy and roughness, pay attention to changes in the grinding force, the old and new diamond wheel  diamond grinding  will greatly increase its instability, therefore, require frequent replacement diamond grinding wheel diamond grinding wheel and the workpiece to  cutter wheels  of . Cam profile and the curve shape grinding, diamond grinding wheel cam bump at the workpiece contact zone trajectory change will lead to changes in the grinding force, resulting in instability occurs  diamond grinding , forming the shape error. Cam grinder difficult to control, and in the coordinate grinder grinding method using interpolation table shaping movement and control methods, it can greatly reduce the above-mentioned factors.
