Abstract: In the machining process, machining accuracy is central to the quality of the machining. Numerous factors often influence the final quality of the workpiece; this article outlines several key factors affecting machining accuracy. Among the many sources of error, machine tools

When drawing up design plans, all manner of tolerances are specified on the drawings, yet in practice, the parts simply cannot be produced to those specifications. Is it that the design precision is too high, or that manufacturing standards are too low? How can we reconcile the drawings with the actual machining process? After reading the following, you might just get the hang of it.

Machining error is the degree of deviation between the actual geometric parameters (geometric dimensions, geometric shape and mutual position) and the ideal geometric parameters of a machined part.
