摘 要: | 为了分析线接触回转铣削外圆柱工件表面加工质量,运用矢量运算方法建立了线接触回转铣削外圆柱工件运动学模型.根据刀齿包络原理,对工件横截表面理论粗糙度几何学形成机理进行了分析,并仿真了顺、逆铣加工条件下的刀齿轨迹.建立了顺、逆铣加工中线接触铣削外圆柱表面理论粗糙度的计算分析模型,提出了顺、逆铣加工理论粗糙度数值计算方法,并分析了各个加工参数对理论粗糙度的影响.经计算比较,该分析及计算方法能精确反映线接触回转铣削外圆柱工件表面理论粗糙度,为加工参数的计算、选择提供了理论依据.

Abstract: | To analyze the machined quality of cylindrical surface with line-contact rotating-milling,the kinematic model of tool-teeth is built based on vector theory.Based on tool-teeth envelope theory,the formation of theoretical surface roughness is studied and the tool-teeth trace is simulated in up-milling and down-milling.The analytic model and calculation method of theoretical roughness of the machined cylindrical surface in both up-milling and down-milling are proposed.The effects of machining parameters on theoretical roughness are discussed.Compared with other methods,the result is more precise to represent the machined surface roughness in line-contact rotating-milling.This approach provides a more precise warranty for choosing machining parameters. |
