As we all know, the reason why the precision parts processing is called precision machining is because of its high processing procedure and process requirements, and the precision of products is very high. The precision of precision parts includes the precision of position, dimension and shape. The following factors affecting the precision of precision parts are summarized
1) The rotary runout of the spindle of the machine tool can produce some errors to the machining precision of the parts.
(2) The inaccuracy of the guide rail can also lead to the error of the shape of the workpiece.
(3) The transmission parts can also lead to the workpiece processing error, which is also the main factor of the surface error.
(4) The different types of tools and fixtures will also have different effects on the precision of the workpiece.
(5) In the process of machining and cutting, the system will be deformed due to the change of the position of the stress point, which will produce difference and the accuracy of the workpiece can be different degrees of error.
(6) The different cutting force will also lead to the influence of workpiece precision.
(7) The error caused by the heating deformation of the process system, in the process of machining, the process system will produce certain thermal deformation under the action of various heat sources.
(7) The deformation of process system caused by heating often results in the influence of workpiece precision.
(8) The deformation of the machine tool caused by heating will cause deformation of the workpiece.
(9) The deformation of the tool will have a great influence on the workpiece.
(10) The workpiece itself is deformed by heating, which is mainly caused by heating during cutting.
