... improvement. The majority of tool wear model is based on cutting condition variations. However, several tool paths with the same cutting conditions lead to different tool lives. The impact of the cutting strategy is significant on tool wear and complex to anticipate. In this article, a global method allowing...

... behaviors is first investigated by differentiating tool path motions, on the basis of the tool path motion expressions in part and machine coordinate systems. A further investigation indicates abrupt kinematic changes to be inevitable when the rotary axes approach a singularity. To eliminate such possible...

...Qin Hu; Youping Chen; Xiaoliang Jin; Jixiang Yang Linear tool path segments of computer numerical control (CNC) machine tools need to be smoothed and interpolated in order to guarantee continuous and steady machining. However, because of the highly nonlinear relation between arc lengths and spline...
