Method for smoothing polygonal contour definitions in NC-programs e.g. for NC machine tools, requires displacing coordinates of original polygonal contour points in geometrical filter unit

摘要

A method for smoothing polygonal contour definitions involves initially transmitting data records containing the coordinate points (P) which are connected by linear segments to represent an original polygonal contour (50), followed by smoothing the latter by displacing the coordinates of the points (P) in a geometrical filter unit so that the resulting polygonal contour (51), consisting of points (P*), is smoothed relative to the original polygonal contour (50).
