Customized Multi-axis NC Programming of Blade Parts

According to the special techniques used in blade spiral NC machining, blade is recognized as a machining feature, then the special multi-axis NC programming is designed and implemented, in which the spiral contact point path and the engage and retract spiral path are constructed, the cut location point by multi-axis method and the spiral path boundary are calculated, as well as the spiral pencil-cut path is constructed, then the high quality and high efficiency paths are achieved.
