NUMERICAL CONTROL APPARATUS AND TOOLPATH DETERMINATION METHOD

A numerical control apparatus acquires a before-machining workpiece shape and an after-machining part shape from a cycle command analyzer that analyzes a machining cycle command and from the analysis result. Then, based on the workpiece shape and the part shape, a machining field is determined, and...

Zusammenfassung:	A numerical control apparatus acquires a before-machining workpiece shape and an after-machining part shape from a cycle command analyzer that analyzes a machining cycle command and from the analysis result. Then, based on the workpiece shape and the part shape, a machining field is determined, and a toolpath of the tool of the machine tool is generated based on the machining field. Based on the shape and the position of the predetermined obstacle and the toolpath, it is determined whether the obstacle is expected to interfere with the tool. When the obstacle is determined to interfere with the tool, the toolpath is modified so that the obstacle will not interfere with the tool.
