An Algorithm to Realize the Real-time Interpolation of Bezier Curves Based on DSP

摘要

As the surface of parts to be shaped is complex, there is a high expectation on accuracy and smoothness during CNC machining. One way is proposed to realize the surface of complex parts based on bezier curves, which is with the advantages of realizing the surface of complex parts in an accurate way. Firstly, the surface of complex parts should be represented by bezier curves; secondly, the bezier curves should be cut in the same length; at last, the pulse signal should be sent to each axis. The experimental results demonstrate that the surface of complex parts which has been shaped meets the expectation on accuracy and smoothness.
