NUMERICAL CONTROL DEVICE |
摘要 |
A numerical control device that controls, in a machine tool, driving of a motor based on a machining program is provided. The numerical control device includes a position-command generating unit configured to generate a position command to the motor and a mark-command generating unit configured to generate a mark command for machining of a mark indicating that an abnormality occurs in the machining. The mark-command generating unit sequentially stores information concerning a moving route of the tool by the machining and generates, when an alarm is raised because the abnormality is detected, as the mark command, a moving command for moving the tool in a direction opposite to a direction during the machining while correcting a position of the tool in a tool axis direction with respect to a position during the machining, and the position-command generating unit generates the position command based on the mark command. |

1. A numerical control device that controls, in a machine tool including a motor for moving a tool for machining of work, driving of the motor based on a machining program, the numerical control device comprising:
a position-command generating unit configured to generate a position command to the motor; and a mark-command generating unit configured to generate a mark command for machining of a mark indicating that an abnormality occurs in the machining, wherein the mark-command generating unit sequentially stores information concerning a moving route of the tool by the machining and generates, when an alarm is raised because the abnormality is detected, as the mark command, a moving command for moving the tool in a direction opposite to a direction during the machining while correcting a position of the tool in a tool axis direction with respect to a position during the machining, and the position-command generating unit generates the position command based on the mark command. |
