Abstract
A system for detecting a damaged tool of multi-axis head machining equipment includes multi-axis head machining equipment, and a damaged tool detecting device connected to the multi-axis head machining equipment to detect a damaged tool, the damaged tool detecting device being configured to measure a current and a current change amount of the multi-axis head machining equipment to monitor a machining load, and a derivative and machining energy of the machining load, so as to detect whether there is an abnormality in a plurality of tools mounted on a multi-axis head during machining.
Claims15
A system for detecting a damaged tool of multi-axis head machining equipment, comprising:
- multi-axis head machining equipment;
- and
- a damaged tool detecting device connected to the multi-axis head machining equipment to detect a damaged tool,
- wherein the damaged tool detecting device is configured to measure a current and a current change amount of the multi-axis head machining equipment to monitor a machining load, and a derivative and machining energy of the machining load, so as to detect whether there is an abnormality in a plurality of tools mounted on a multi-axis head during machining, and
- wherein the multi-axis head machining equipment comprises:
- multi spindles configured to mount the plurality of tools thereon;
- a spindle motor configured to rotate the multi spindles;
- a shaft feed motor configured to linearly move the multi spindles;
- a current supplying device connected to the spindle motor and the shaft feed motor via a power line to supply a current to both motors;
- a programmable logic controller (PLC) circuit;
- and
- a programmable motion controller (PMC) circuit.
A method for detecting a damaged tool of multi-axis head machining equipment, the method comprising:
- initiating machining performed by the multi-axis head machining equipment;
- and
- by a damaged tool detecting device connected to the multi-axis head machining equipment, detecting whether there is an abnormality in a tool during machining of the multi-axis head machining equipment,
- wherein, in detecting whether the abnormality is present in the tool, machining load monitoring, derivative of the machining load monitoring and energy of the machining load monitoring are sequentially performed by the damaged tool detecting device.
