The Task of Grinding of Casting Surfaces with Industrial Robots

Abstract

Increasing use is being made of industrial robots in the more sophisticated area of tooling. Up to now they are applied to tasks of coating, welding and fettling. Furthermore, they are going to be used for the task of grinding surfaces of bathroom fittings. In a first step the robot has to do the rough grinding. To get an optimal control of the process special efforts are indispensable concerning the mechanical construction and the robot control. The kinematic design of the robot and the control system determine the expenditure controlling the grinding process. Regarding some essential facts it becomes easy to have an essential connection between the grinding process and the robot movement. Concerning the sensor one also can reduce the expenditure of software if the robot CNC (Computer Numerical Control) is adapted to the special task of machining.
