ABSTRACT:
There is disclosed a method of and apparatus for improving surface finishing and accuracy in a grinding operation employing a manipulator such as a robot which is coupled to a rotary grinding tool. The method comprises reducing the coupling effects between the tool motion whick is tangential to a workpiece surface and tool motion which is normal to the surface to obtain the optimum performance. The method involves adding compliance to the grinding tool in the tangential direction while maintaining higher stiffness in the normal direction. A robot is disclosed which is made in accordance with the method.
