一般而言，零件的成本随着公差的减小而上升。
Generally speaking, the cost of a part goes up as the tolerance is decreased.
对较大公差的零件，烧结后可放回模具重新挤压。一般而言这会使零件更精确同时具有更好的表面光洁度。
For high tolerance parts, a sintering part is put back into a die and repressed. In genera this makes the part more accurate with a better surface finish.
在机械设计中，装配尺寸链的组成环公差，一般是采用等公差法或等精度法来确定。
During machine design, tolerance of unit ring in assembly dimension chain is usually determined by using either equal tolerance or equal accuracy method.
