In machine tool processing, the factors that affect the machining accuracy of workpieces mainly include the following aspects:
(1) Minor shape errors of cutting tools and equipment errors on machine tools.
(2) Equipment error of workpiece on machine tool.
(3) The errors in the machining principle of machine tools.
(4) During the cutting process, the oscillation, elastic deformation, thermal deformation, and tool wear of the machine tool tool workpiece system occur.
(5) A few errors in the machine tool.
(6) Transmission errors in the machine tool transmission chain.
