1. Accuracy of machine tool itself Generally speaking, the machine tools that produce workpieces have coordinate axes. If the accuracy of the coordinate axis of the machine tool is not high, the deviation of positioning accuracy will cause dimensional errors of the workpieces produced by the machine tool, resulting in a large number of workpieces.

Wheat milling can be considered as a fractionation process and its performance is influenced by grain hardness and biochemical factors (such as protein content). The term grain hardness or endosperm texture is used to differentiate 'soft' and 'hard' hexaploid wheats and is defined as the grain's resistance to deformation.

Highefficiency milling (HEM) is a roughing strategy that can be used to help increase a machine's MRR as it combines a lower RDOC and a higher ADOC, providing a consistent wear across the cutting edge, generating less heat, and allowing for increased speed. HEM differs from traditional milling in two distinct ways.
