ABSTRACT:
A desired curved path is approximated by spline segments, which in their entirety define the path of motion for a machine-tool or for a robot. The deviation in position of this path of motion from the desired curved path is maintained within a specified tolerance band. Through an iterative process, the path of motion is formed with the fewest possible spline segments. If two many spline segments were used, they could overtax the processing speed of a numerical control system. But, on the other hand, the interpolation of spline segments is technically a relatively simple process.
