| Abstract: | Based on analysis of interpolation mechanism for parametric curve, in this paper, 2D and 3D spiral curves interpolation algorithms with constant feedrate are developed on the one hand and the contour errors and corresponding approximate calculation formulations are discussed on the other. With simulation examples of proposed spiral interpolation algorithms which programmed in graphics developing language AutoLISP, as a result, it shows that there are no contour errors and there are some very useful features such as constant feedrate and interpolation precisions easily being controlled, etc. Moreover, it will be very convenient to be developed and applied as an advanced interpolation function for modern gerneral PC microcomputeried numerical controlling system. |
