Abstract
This machine tool is provided with: a sensor (30-1, 30-2, 30-3, 30-4) which is disposed in the vicinity of an opening for loading a workpiece and which measures the motion of an object approaching the opening; a storage unit (18) storing a rule for classifying non-processing time into setup time and non-setup time on the basis of the motion of the object relative to the sensor; a determination unit (14) which, when a processing program is not being executed, determines whether the current state of the machine tool corresponds to setup time or non-setup time on the basis of the motion of the object and the rule stored in the storage unit; and an output unit (20) which produces an output indicating whether the current state of the machine tool corresponds to setup time or non-setup time.
Claims8
A machine tool for machining a workpiece based on a machining program, the machine tool comprising:
- a sensor which is arranged in a vicinity of an aperture for introduction of a workpiece and which measures a target movement near the aperture,
- a storage unit in which there are stored rules for dividing a non-machining time into a setup time and a non-setup time based on the target movement measured by the sensor,
- a determination unit which determines, when the machining program is not being executed, whether a current state of the machine tool is a setup time or a non-setup time based on the target movement and the rules stored in the storage unit, and
- an output unit which outputs whether the current state of the machine tool is a setup time or a non-setup time.
A production system for producing a product with a plurality of machine tools which machine a workpiece based on a machining program, the production system comprising:
- a plurality of machine tools in which a sensor is arranged in a vicinity of an aperture for introduction of a workpiece and measures a target movement near the aperture,
- a process management device for managing processes of each of the machine tools, the process management device comprising a storage unit in which there are stored rules for dividing a non-machining time into a setup time and a non-setup time based on the target movement measured by the sensor, a determination unit which determines, when the machining program is not being executed, whether a state of the machine tool is a setup time or a non-setup time based on the target movement and the rules stored in the storage unit, and an output unit which outputs whether the state of the machine tool is a setup time or a non-setup time, and
- a display which displays the setup time along a time axis based on the state of the machine tool transmitted from the transmission unit.
