Background

When a workpiece needing to be processed on the front surface and the side surface is encountered, the front surface needs to be processed and then the workpiece needs to be turned over and clamped, so that the following problems can be caused: 1. the positioning error of the machine tool positioning error refers to the maximum variation of the design standard of the machine tool workpiece relative to the clamp or the machine tool in the machining size direction when the workpiece is clamped and positioned. Machine tool positioning errors are related to positioning methods, including reference displacement errors caused by positioning references not coinciding with design references or process references. 2. The jig manufacturing error refers to the error generated when a machine tool is manufactured, assembled or worn. 3. The clamping error refers to an error caused by deformation of a workpiece due to a clamping force in a clamping process of the workpiece with a weak structure; for example, when a thin-walled sleeve is clamped by a three-jaw self-centering chuck, the sleeve is elastically deformed by a clamping force, and the sleeve is formed in a triangular ring shape. Although the hole is turned into a perfect circle, after the clamp is loosened, the sleeve is partially deformed and restored, so that the hole is formed into a triangular prism shape, and a large shape error is generated.
