Assignee: KOREA INSTITUTE OF INDUSTRIAL TECHNOLOGY
Field: Handling (Mechanical engineering)
Classification: CPC B  G | IPC B

Claim 6:
7. A method for adjusting a machining load using the robot system for adjusting the machining load depending on tool wear according to claim 1, the method comprising:
i) a step in which the sensor unit measures the amount of current supplied to the machining motor;
ii) a step in which the controller receives the measurement signal from the sensor unit;
iii) a step in which the controller derives the machining load value of the machining unit based on the average of the value of the measured amount of current supplied to the machining motor and the value of the operation force of the tool, and compares the machining load value of the machining unit and the reference machining load value;
iv) a step in which the controller transmits a control signal to the robot or the support when the machining load value of the machining unit is larger than the reference machining load value; and
v) a step in which a movement speed of the machining unit with respect to the machining target is decreased under operation control of the robot or the support.
