NUMERICAL CONTROLLER FOR SMOOTHING TOOL PATH IN OPERATION BASED ON TABLE FORMAT DATA

摘要

Positions to be synchronized with a reference value are stored as command data in table format. Velocity changing points of a tool path designated by the table format data are calculated. Two intersection points between the tool path and a circle or a sphere having a designated radius and centered on the velocity changing point are connected by a smooth curved tool path according to a multidimensional function or the like. In this way, the table format data is corrected.
