Abstract

This paper focus on the tolerance synthesis of a parallel robot manipulator with 3Revolute joints. The present work deals with making the dimensions of the robot manipulator robust and compute the optimal dimensional tolerances for a given 3R parallel robot manipulator for minimising the positioning error of end effector of robot with given target.For making the dimensions robust a proper robustness index has to be chosen.Obtained robust dimensions must tolerate globally to largest variations. Then to compute the optimal dimensional tolerances from the given robust dimensions a new tolerance synthesis method developed by Stephane Caro is used .This method is known as Caro-Tolerance box method. the optimal dimensional tolerances are calculated by optimal dimensional algorithm.The values of robustness index and optimal dimensional tolerances are validated.
