机械加工于外圆和孔等旋转外貌而言，，， ，加工余量是从直径上思量的，，， ，故称为对称余量（即双边余量），，， ，即现实所切除的金属层厚度是直径上的加工余量之半。。。。平面的加工余量则是单边余量，，， ，它即是现实所切除的金属层厚度。。。。在工件上留加工余量的目的是为了切除上一道工序所留下来的加工误差和外貌缺陷，，， ，加工需要的机械由数显铣床、数显成型磨床、数显车床、电火花机、万能磨床、加工中心、激光焊接、中常用机械丝、快走丝、慢走丝、外圆磨床。。。。

For mechanical machining on rotating surfaces such as outer circles and holes, the machining allowance is considered from the diameter, hence it is called symmetrical allowance (i.e. bilateral allowance), which means that the actual thickness of the metal layer cut is half of the machining allowance on the diameter. The machining allowance of a flat surface is the unilateral allowance, which is equal to the actual thickness of the metal layer cut. The purpose of leaving machining allowance on the workpiece is to remove machining errors and surface defects left by the previous process. The required machinery for machining includes digital milling machines, digital forming grinders, digital lathes, electric discharge machines, universal grinders, machining centers, laser welding, commonly used mechanical wires, fast wire, slow wire, and cylindrical grinders.
