    Sep 04, 2021 The distribution characteristics of machining errors in high energy efficiency milling are an important index to evaluate the surface geometry parameters, cutting stability, and dynamic cutting efficiency. The existing methods for machining errors focus on the overall level of the parameters of a machined surface and the degree of deviation from the index and ignore the influence of the
