Practical Research Of Capp Technique According To Quality Examination Principle

This paper aims at researching and developing CAPP technique which can make up bad credibility, large amount of filling blanks, low efficiency designing, accuracy of data and sharing problem in information in traditional technological design method.This system has researched and developed comprehensive.mold piece turning with certain integration system according to the comprehensive developing mode. In general setting up and partial structure, this system has embodied comprehensive type development strategy, adopting a characteristic coding technique to carry on spare parts information, using object-oriented operating mode craft to carry out open structure of database,auto born and outputting craft document. The structure and establishment of open researching database are as follow;building up a foundation database, an information model database, a spare part template craft database and a craft rule database; researching the description method of spare parts information characteristics and information importation method, with the craft data of existing craft spare parts collected in database; building up spare part of information model; researching the principle of craft decision and realization; summing up a craft, designing craft template. Born rules of researching craft born model and exportation method of the craft document.In order to make various crafts of system more accurate and match actual production, we lead into examination of quality, combining which with CAPP, using faintness method of gathering type, forming controlling diagram-work preface stability judgment-work preface ability calculation-gather a type of analysis of excellent turn, taking the engineering solid example as represent to calculate and compare characteristic expressed for processing from design, produce to examination. We have built up the ones to CAPP system craft process of excellent process by taking production craft as terrace, gathering design, analysis, optimizing and controlling tool.Designing and creating CAPP system, whose basic principle is advanced, practical, efficient and vivid, need to deal with the antinomy good adaptability and in general use, namely well embody system and in general use in macro view, coordinating and adapting in micro view with technique combining the two times.Applying mathematical statistics and part of related knowledge carry on a control to the product quality and give the valuation of logical reasonable to the CAPP work preface. Put forward optimization. Combining CAPP and quality examination, we realized sharing resources and exchanging information of real meaning to make the two a continuous process by modifying the craft.
