Reverse Design and Rapid Prototyping ABS Part Assembly with Hard Material

Abstract

In order to realize the variant design of the existing product , and rapid completion of the manufacturing and assembly, a new product was designed by reverse design method,and manufactured by rapid prototyping technology to finish assembly with hard material part. An experiment of rapid prototyping part with different model scales assembling with metal part was done to find the right scale of 1.008 of the model in H/h tolerance fit and 0.1mm more in size in interference fit. Through the static theory analysis, the amount of the interference fit was calculated by equal torque in contrast with mechanical assembly.The result was further proved by ProE mechanica simulation for stress and strain. Applying the rule of the results in experiment,prototyping part assembly with hard material part in different types of fit can be realized.
