Research on the Rapid Determining Method for Roughcast Allowance and Tolerance
Roughcast allowances have an important effect on machining quality and production cost. In this paper, based on the analysis process of machining and the method of roughcast manufacturing, the factors influencing on determining roughcast allowances are studied systemically, and the key influencing factors are found out. On the basis of this, a method for rapid determining roughcast allowances and tolerance based upon ANN is presented, ANN model is set up, and unitary processing about input factors is finished. It is proved via the example analysis and simulation experiment that roughcast allowances and tolerance can be rapid determined only by selecting rational and logical network frame and sample parameters.
