摘要
通过对几种典型零件在切割过程中的热应力分析.特别是对采用多割嘴(三只或四只)同时切割的分析,表明产生切割变形的主要原因是合应力的作用.分析合应力,找出影响零件尺寸精度的主要因素.改进切割程序,达到了控制切割变形的目的.
After analysis for a number of workpieces cutting espcial for multi - nozzle (3 or 4 ) cutting, the key factor for the occurrence of distortion isthe action from the resultant forces. From this point, the factors which affect the size accuracy arc found out and the progam for cutting process is improved and distortion controlled.
