Establishment of Special Fixture Parts Library and Computation of Location Error by SolidWorks

In order to improve the efficiency of special fixture design and positioning accuracy,standard parts library and non-standard components feature library were established with SolidWorks Second Development Technology,some examples were given to explain how to build up library of special fixture parts.A method of location error calculation aided by SolidWorks assembly-size measuring tool was put forward based on common error analysis.This method can shorten the design cycle,ensure the accuracy of location error calculation,raise the level of automation in special fixture design.
