This paper proposes an in-situ grinding mechanism driven by cables and supported by discrete elastic backbones. By means of geometric analysis and coordinate transformation under D-H convention, the forward and inverse kinematics models of the mechanism are established and verified.

Introduction: The shaper is a machine tool used primarily for: 1. Producing a flat or plane surface which may be in a horizontal, a vertical or an angular plane. 2. Making slots, grooves and keyways. 3. Producing contour of concave/convex or a combination of these. Working Principle: The job is rigidly fixed on the machine table. The single ...
