摘要: In Part 2 of this two-part paper, we describe a new quintic spline interpolator for real time trajectory generation during free form curve machining on the Open Architecture machine tool platform described in 1. The research provides capabilities advanced CAD/CAM systems. Complicated curves and shapes designed CAD system are usually represented by set discrete data points. Subsequently manufacturing CAM system. these points need to be converted into paths machining. Therefore, paper presents interpolation method that interpolates designated with real-time path generation. resultant curve, generated proposed method, is nearly arc-length parametrized has C 3 continuity. near parametrization property makes reference commands cutting easier. continuity guarantees smooth motion continuous speed, acceleration even jerk combined properties enable developed
