(1) Spindle runout of the machine tool can cause certain errors to the machining accuracy of the parts.
(2) Inaccurate precision of machine tool guide rails can also lead to errors in the shape of workpieces processed by precision parts.
(3) Transmission parts can also cause errors in workpiece machining, which is also the most important factor in workpiece surface errors.
(4) Different types of tools and fixtures will also have varying degrees of influence on the accuracy of the workpiece.
(5) In the process of machining and cutting, due to the change of the position of the force point, the system will be deformed, resulting in differences, and the accuracy of the workpiece will also have different degrees of error.
(6) The size of the cutting force is different, which will also affect the accuracy of the workpiece.
(7) Errors caused by thermal deformation of the process system. During the machining process, the process system will produce certain thermal deformation under the action of various heat sources.
(8) The deformation of the machine tool due to heat will lead to the deformation of the workpiece.
(9) The thermal deformation of the tool will have a great impact on the workpiece.
(10) The workpiece itself is deformed by heat, which is mainly caused by heat during the cutting process.
