摘　　要：旋风铣削加工中,工艺系统的几何误差、热变误差和刚性变化使工件与工具表面交线不是理想的螺旋面包络线,其位置也产生了偏差,影响到加工工件质量.以旋风法应用最多的螺纹加工为例,分析了工件受力与热变形对包络线位置的影响,螺纹中径螺距等衡量互换性重要指标的变化情况及近似计算式,它们随加工点位置不同而不断变化.In whirling machining process,the hand -over -line of workpiece and tool face isn＇s an ideal spiral noo- dles wrap line because of the geometry error,heat change error and rigid varity. Its position also shows deviation. As a result, the quality workpiece is affected. Taking the thread process in whirling machining for instance, the writer analyzes the influence of the position of wrap line caused by the workpiece which is subjected to dint and heat transfrom,and hte variety of the important index which weighs compatibility such as pitch and screw center diameter. Their change and calculation formula vary with the different positions of the process point.
