The invention relates to an intelligent force control
robot grinding system. The intelligent force control
robot grinding system comprises a computer, an industrial camera, a
robot, a
robot controller, a calibration and compensation
system, a safety protection unit, a
force sensor and an automatic knife changing system. The computer is connected with the industrial camera. The
robot controller is connected with the computer, the robot, the calibration and compensation system, the safety protection unit, the
force sensor and the automatic knife changing system. A method comprises the steps that the computer receives workpiece scanning data collected by the industrial camera, generates a knife path and converts the knife path into the robot posture and the
tail end path; calibration and compensation are carried out; the
robot controller controls all joints to move while the robot posture and the
tail end path are adjusted. Hardware of a high-precision force control
grinding system is achieved, the path self-calibration and online compensation technology is adopted, and the
machining of a complex hook face with the high requirements for
machining precision and
surface smoothness can be finished.
