During the design of mechanical parts, the tolerance allocation of each component has made the designer the most difficult place. Before, the way of the engineer to decide tolerance allocation is simply by their own experience , as well as checking the standard tolerance chart. However, considering the cost, those may not be the optimal method .So that, we apply the Response Surface Methodology (RSM) to decide the optimal allocation for each component. RSM combined with statistical and mathematical applications . By the studies of reactive value caused by multiple variations, and the best outcome of the reactive value, that will be the best method for the model establishment and problems analysis . Under the least costing purpose, by using SAS RSREG procedure to do the analysis of Response Surface, and find out the optimal tolerance value of each component. Together with the cost of regression model to change the tolerance value in order to evaluate the final cost.
