NC Processing Craft Decision-making And Cutting Parameter Standardization Research

The NC processing craft decision-making in the numerical control processing process is complex the extremely important link, with the processing procedure establishment, the components processing quality, the benefit all have the close relationship. Craft decision-making quality, not only can affect the engine bed efficiency the isplay, moreover directly will also affect the components the processing quality. Therefore, the NC processing craft decision-making research to enhances is processed the components the precision, enhances the working efficiency, thus enhances the enterprise the economic efficiency, has the necessity extremely.This article through to NC processing craft characteristic theoretical analysis and research, has established based on NC processing element CNC-ME(CNC Manufacturing-element) with NC processing craft element CNC-WE(CNC Work-element) creates in the type CAPP system to have the hierarchical structure NC processing craft decision-making model, elaborated in the NC processing craft decision-making process the principle which to separate and the reverse centralism principle and the labor step, the working procedure priority craft route is producing.In NC processing, reasonably chooses the cutting parameter to guarantee the product quality, to enhance the productivity correctly, reduces the production cost to play the extremely vital role. In recent years, along with NC technology universal application, as well as each kind of advanced technique of manufacture rapid development, produces the non-cutting time to reduce greatly, correspondingly, the cutting time occupies the proportion greatly enhances. Therefore reduction machining time, to enhances the productivity to play the vital role. At present, the majority factories depend on the experience or the reference cutting specifications handbook in the production choose the cutting specifications, this often cannot achieve the cutting parameter optimal. Using the modern cutting theory, mathematics modelling and the model analysis method seek the cutting parameter the most superior combination, is cuts the parameter choice an important direction.This article uses one kind based on the characteristic numerical control processing craft production way. elaborated with this way correlation characteristic technology, the NC processing craft knowledge and the resources storehouse, the NC processing side metric chain as well as matches the NC processing parameter, the cutting tool, the jig and so on the production way. Proposed one kind-changes the search territory genetic algorithm based on the gene algorithm cutting parameter optimization method. Compares with the usual optimized algorithm, this method computation load is small, the computation speed is quick, can adapt the automated manufacture system to optimize the cutting data fast response the request. In cutting parameter optimization research foundation, has developed the NC processing cutting parameter management and the optimized system. This system completion liberates with the use the craft personnel from the massive manual repetition work, and realizes the cutting parameter selection scientific style, the rationalization, the standardization, has created the good economic efficiency for the enterprise.
