[0002] In mechanical processing production, the processing of circular arc surface workpieces is often encountered. For the processing of circular arc surfaces, the earliest methods are manual repairing or tool setting on a boring machine according to the marking line, and manual angle grinder or grinder is also used for processing. , so that the processor must have a considerable degree of proficiency, and the processing quality is difficult to guarantee, the cost is high and the actual precision requirements are not met, and the efficiency is low and the labor intensity is high.

In order to improve the machining accuracy, the existing more commonly used arc surface processing method is to install a single workpiece on the CNC machine tool, and use the forming R milling cutter or ball nose cutter to approximate the arc milling, and the arc surface retains a certain margin. Then use the diamond pen of the coordinate grinding machine to trim the grinding wheel into a reverse shape that completely matches the forming surface of the workpiece for grinding, or use a disc-shaped grinding wheel (oil stone) to grind along the arc track under the numerical control system. There are certain safety factors in the rigid grinding of the grinding wheel, such as the workpiece needs to be repositioned, etc.; if the arc surface of the part installed on the machine is to be ground, the part needs to be removed to be ground on the machine tool, and the condition is not allowed. There are site limitations
