数値制御装置、数値制御プログラム、及び、数値制御プログラムを記憶した記憶装置
Document Type and Number:
Japanese Patent JP7036071
Kind Code:
B2
Abstract:
To provide a numerical control device, a numerical control program, and a storage device that stores the numerical control program, which can shorten the tool change time while avoiding the risk of collision between a spindle head and a tool.SOLUTION: In a tool change process, a CPU of a numerical control device moves a spindle head 7 from a machining area to a tool change position (S15). The tool change position is a position above a mechanically-predetermined specific position that can avoid a collision between the spindle head 7 and a tool 4. When the rising spindle head 7 passes the specific position (S17: YES), a CPU 31 starts rotating a magazine body 71 (S19). Therefore, the spindle head 7 can avoid the risk of collision with the tool 4. As the time when the spindle head 7 reaches the specific position is earlier than the time required when a stop target position of the spindle head 7 rising from the machining area is the specific position, the start time of rotation of the magazine body 71 is accelerated and the tool change time is shortened.SELECTED DRAWING: Figure 10
