This paper presents a closed-form solution of the swept profile of a generalized cutter in five-axis numerical control (NC)
machining.The machine configurations and tool movements defined in NC programs are considered to model the true machine
tool trajectory,which includes the linearly translational and rotational movements.Based on the machine tool trajectory and the
cutter geometry,the cutter’s instantaneous swept profile is determined.By integrating the intermediate swept profiles,the cutter’s
swept envelope can be constructed and applied to NC verification.The proposed method provides the explicit solution of the swept
profile of a generalized cutter,which is important but not possible in the existing methods for five-axis NC verification.The
computer implementations show that the approach developed is superior to the traditional methods.

本文介绍五轴数控(NC)机床中,生成刀具扫描仿型靠模的密闭形办法.在数控程序中定义的机床启动和工具运动,都被考虑为模拟真实机床工具的轨迹,包括线性传送和旋转运动.根据机床工具轨迹和刀具几何形状,决定了刀具的瞬时扫描靠模的动作.把过渡的扫描的靠模进行积分,刀具的扫描包络线就形成了,然后送至数控机床进行核实.所建议的方法提供了生成刀具扫描靠模的明确的办法,这一点是重要的,但现存的方法对于五轴的数控机床的审核尚不可能.电脑的执行程序表明,此处所研发的手段胜过传统的方法.
