Abstract
Official abstract text for this publication.
A machining path creation device includes an analysis unit configured to create a machining path by analyzing a machining program, a shape determination unit configured to determine ON/OFF of a smoothing processing function at each part of the machining path, based on the shape of each part of the machining path created by the analysis unit, and a smoothing processing unit configured to perform smoothing processing on a part of the machining path in which the smoothing processing function is determined to be ON, and not to perform smoothing processing on a part of the machining path in which the smoothing processing function is determined to be OFF, based on a determination result obtained by the shape determination unit.
First claim
Opening claim text (preview).
1 . A machining path creation device that creates a machining path that is a movement path of a tool with respect to a workpiece based on a machining program, the machining path creation device comprising: an analysis unit configured to create a machining path by analyzing the machining program; a shape determination unit configured to determine ON/OFF of a smoothing processing function at each part of the machining path, based on a shape of each part of the machining path created by the analysis unit; and a smoothing processing unit configured to perform smoothing processing on a part of the machining path in which the smoothing processing function is determined to be ON, and not to perform smoothing processing on a part of the machining path in which the smoothing processing function is determined to be OFF, based on a determination result obtained by the shape determination unit. 2 . The machining path creation device according to claim 1 , wherein the shape determination unit determines a shape of each part of the machining path based on a curvature at a command point of the machining path. 3 . The machining path creation device according to claim 1 , wherein the shape determination unit determines a shape of each part of the machining path based on a change in curvature at a command point of the machining path.
