Abstract:
The NC
interpolation algorithm for the parallel machine tools is investigated.
The algorithm which can be implemented by two steps, i . e . the rough
interpolation in the Cartesian space and the precise interpolation in
the actuator space. The upper bound of the theoretical error due to the
PVT algorithm in the precise interpolation and nonlinear mappling is
analyzed. Analyzed. It concludes that this error is negligible provided
that the machine operates at low and middle speed.
Key words:
