| Abstract: | A rough and precise interpolation strategy and algorithm for a new type parallel machine tool is presented. The machining surfaces are interpolated directly in the rough interpolation step. Taking NURBS curve as an example, the interpolation formulas are deduced by a rational calculation method, and the errors of rough and precise interpolation are analyzed. Results of an interpolation example show that the interpolation algorithm is featured of constant rate feed and machined surface contour error being controlled easily. |
