Curve fitting is another important feature of the HSM capable NC post-processor.The fitting can be used either to convert piecewise linear interpolation to curved motions or, to convert CAM generated curved motions to the type of interpolation supported by the machine's controller. The last point is especially important with regards to 5-axis machining. When converting a CAM motion (X,Y,Z tool tip part position and I,J,K tool axis vector) to the NC tape (e.g.: X,Y,Z machine linear axes position and A,B rotary heads) the application of inverse kinematics makes the output curve completely different from one generated by the CAM system. The fitting process can come to help here, by producing NURBS or other types of curves that can be understood by the controller. In addition, with regards to better cutting conditions using NURBS or Arc Fitting has other beneficial effects. First, it significantly shortens generated NC tape, thus making any data transfer easier. Second, the possibility of arriving at data starvation conditions decreases while sequences of short motions are combined into one longer motion。
各位老大多多提意见啊！拜谢了。我现在就是还处于找研究内容的阶段。
