Abstract
This method, for controlling a machine tool using a tool holder to which a coolant pipe is attached, includes: a step of detecting, in response to a signal indicating that a tool is prepared on a tool loading station of the machine tool, whether or not an abnormality has occurred in attaching the coolant pipe to the tool holder of the tool while the tool holder is at the tool loading station; and a step of issuing an alarm when the abnormality is detected in the step of detecting the occurrence of the abnormality.
Claims5
A machine tool using a tool holder to which a coolant pipe is attached, the machine tool comprising:
- a tool magazine,
- a tool loading station provided adjoining the tool magazine and configured as a relay part for receiving from outside the machine tool a tool to be transferred to and stored in the tool magazine and for receiving a tool taken out from the tool magazine to be removed to the outside of the machine tool,
- a coolant pipe detection device for detecting the coolant pipe to be attached to the tool holder when the tool to be stored in the tool magazine is at the tool loading station together with that tool holder, and
- a controller making the coolant pipe detection device operate triggered by a signal showing that the tool to be stored in the tool magazine is ready at the tool loading station while the tool holder for the tool is at the tool loading station, judging any abnormality in attachment of the coolant pipe based on a signal from the coolant pipe detection device, and issuing an alarm when judging there is an abnormality.
