Abstract
Provided is a numerical control device that eliminates the need for rapid acceleration/deceleration of a cutting tool during boring and that is capable of minimizing vibration of a machine tool. This numerical control device comprises: a deep hole boring execution unit which performs deep hole boring by repeating a cutting operation for making a cut in a workpiece while rotating the cutting tool and a cutting halting operation for halting the cutting operation of the workpiece while rotating the cutting tool; and a chip-discharging time calculation unit which calculates a chip discharging time depending on the position of the cutting tool after each cut during the cutting operation. The deep hole boring execution unit performs the cutting halting operation during the chip-discharging time.
Claims5
A numerical control device comprising:
- a deep-hole drilling execution unit configured to carry out deep hole drilling by repeatedly performing a cutting operation of causing a cutting tool to cut into a workpiece while rotating the cutting tool and a cutting stop operation of stopping the cutting tool from cutting into the workpiece while rotating the cutting tool;
- and
- a chip removal time calculation unit configured to calculate a chip removal time in accordance with a position of the cutting tool at an end of each cutting in the cutting operation,
- wherein the deep-hole drilling execution unit performs the cutting stop operation for the chip removal time.
