锻件的余量与公差及其公称尺寸的计算确定法

Calculation for Tolerance Allowance and Basic Size of Forgings

在锻造工艺及模具的CAD/CAM中,过多的数据表造成对硬件及软件的要求提高,投资及运行费用增大。为解决这一问题,本文对锻件的余量与公差及其外形尺寸的确定,提出了计算法,推出了可行的计算公式并与“JZ”资料中的表值作了比较。采用本法,使大程序在微机上运行得以保证。

In CAD/ CAM technology of forging processes and dies, the reguest to electronic computer and porgramme are made to increase by a great of date tables, and the tables, and the take are increase too, In order to avoid that, Analgorithm is developer in the poper to delermine the allowance tolerance and basic size of forgings. The feasiable formulas are given At last. the calculaling value are competed with tables yalcue of 'JZ' date Take this cal culation It is possibile that minitype electronic computer work with large programme.
