Abstract
A tool path generation device that calculates a tool path to be used by a machine tool device, and that provides a high machining efficiency with suppressed occurrence of chatter vibration by calculating machining conditions in consideration of a chatter vibration increase and decrease affecting value that affects increase and decrease in chatter vibration.
Claims20
A tool path generation device that calculates a tool path to be used by a machine tool device that machines a workpiece using at least one tool, characterized by comprising:
- an affecting value calculation section that calculates a chatter vibration increase and decrease affecting value that affects increase and decrease in chatter vibration caused in a structure formed by the tool, the workpiece, and the machine tool device on the basis of whether or not a direction of the chatter vibration or vibration characteristics of the structure are known;
- a machining condition decision section that decides machining conditions on the basis of the chatter vibration increase and decrease affecting value calculated by the affecting value calculation section;
- and
- a tool path calculation section that calculates the tool path on the basis of the machining conditions decided by the machining condition decision section.
(canceled)
A tool path generation method for calculating a tool path to be used by a machine tool device that machines a workpiece using at least one tool, characterized by comprising:
- a step of calculating a chatter vibration increase and decrease affecting value that affects increase and decrease in chatter vibration caused in a structure formed by the tool, the workpiece, and the machine tool device on the basis of whether or not a direction of the chatter vibration or vibration characteristics of the structure are known;
- a step of deciding machining conditions on the basis of the calculated chatter vibration increase and decrease affecting value;
- and
- a step of calculating the tool path on the basis of the decided machining conditions.
A tool path generation program for calculating a tool path to be used by a machine tool device that machines a workpiece using at least one tool, characterized by comprising:
