摘要
机械加工中工序尺寸关系复杂的零件,其工序尺寸、公差及余量的确定问题,需用工艺过程尺寸链作综合分析与计算.本文试图改变传统的方法,依靠建立数学模型,利用数学计算求解该问题,使其结果(数据)更为合理和准确。
Comprehensive analysis and computation of process dimensional chains are necessary for determination of operational dimensions, tolerances and allowances of machine elements with complex operational dimensions involved in machining processes. This paper attempts to propose a new approach by means of mathematical computation based on the proper mathematical models, which gives more reasonable and correct results than conventional methods.
