【摘要】 以美国 Y1 4.5.1 M- 1 994标准为标志的公差数学定义理论使以两点测量法为基础的传统公差理论面临挑战。基于漂移区的尺寸公差语义 ,结合我国国标中的公差原则 ,对尺寸公差的数学定义进行研究 ,提出相应的一致性验证的充分与必要条件 ,对促进公差验证系统的发展有重要意义。更多还原

【Abstract】 The emergence of formal tolerance mathematical definition theory,American new standard Y14.5.1M-1994,challenges the traditional theory based on two-point measurement metrology.Based on offset-zone semantic and tolerance rule of current chinese standards,this paper studied the mathematical definition of size tolerance and presents sufficient and necessary conditions for tolerance consistence test.It has significant values in promoting the development of tolerance test system.更多还原
