摘要

Increasing demands on precision mahining of free-form surfaces have necessitated the tool to move not only with position error as small as possible,but also with smoothly varying feedrates.In this paper,linear,circular and spline interpolators were develoepd in reference-pulse type using PC.M_SAM and M_DSM were designed by the comparison and analyssi of previous interpolation methods.Spline interpolator was designed to follow the free-form curves.To apply to the real cutting process,constant feedrate compensation and acceleration-deceleration compensation were conceived.Finally,its performance was tested using retrofitted milling machine.As a result,new interpolatio algorithm is favorable inprecision maching of free-form curves.
