    機械加工于外圓和孔等旋轉(zhuǎn)表面而言，加工余量是從直徑上考慮的，故稱為對稱余量（即雙邊余量），即實際所切除的金屬層厚度是直徑上的加工余量之半。平面的加工余量則是單邊余量，它等于實際所切除的金屬層厚度。在工件上留加工余量的目的是為了切除上一道工序所留下來的加工誤差和表面缺陷，加工需要的機械由數(shù)顯銑床、數(shù)顯成型磨床、數(shù)顯車床、電火花機、萬能磨床、加工中心、激光焊接、中常用機械絲、快走絲、慢走絲、外圓磨床。

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.
