Machining errors refer to the degree of deviation between the actual geometric parameters (geometric dimensions, geometric shape and relative positions) of a part after machining and its ideal geometric parameters. The degree to which the actual geometric parameters of a part after machining conform to its ideal geometric parameters is known as machining accuracy. The smaller the machining error,

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.

The manufacturing error of the machine tool covers various aspects such as spindle rotation error, guideway error and transmission chain error. Spindle rotary error, that is, the spindle in the actual rotary process, its axis and the average axis of the deviation between, which is directly related to the accuracy of the workpiece processing.

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.

01 Error and accuracy of the “twin faces” of the smaller the machining error, the higher the degree of compliance, the higher the machining accuracy. Both actually describe the same thing - just a different perspective. In other words, the size of the error directly determines whether the part can meet the standard!
