Development And Reseach Of The Applications Of Tolerance And Fits

With the rapid development of manufacturing information, the choice of tolerance and cooperation has increasingly become an indispensable part of the process of mechanical and electrical product design, manufacturing, testing, assembling. However, the traditional method that with the calculation of tolerance and fit manual query and extract data is a waste of time and relatively large error, cannot meet the engineering needs. Therefore research and development a set of query module of tolerance and fit, tolerance and cooperation calculation, data processing and other functions in one application tolerance and fit into the general engineering and technical personnel of the urgent need to study this subject is put forward so .It is based on the VC++,ASP,data base technological achieve one suit of software which can achieve the design data inquiry, tolerance and concert inquiry, tolerance concert calculation dimensions link calculation, gear accuracy calculation, Place degree error measure data handling, The Expert System dimensional tolerance designed and the coarse degree on face design of expert system, design data behind-the-scenes backers administer to replace system and software behind-the-scenes backers system official business falls short of to design and so on excellent service capacity system software。In addition, the software design process data as a mechanical indispensable "standard data", without exception, according to certain principles, to comply with certain principles of mechanical design selected.The principal results of the system are:Update the feature of calculation of Tolerance and fits and calculation of size chain. Have the rich proscenium excellent service capacity, can achieve message datum dynamic expansion replaces. Moreover on these base use technique of ASP and draw to stir the space of whole page in browser to administer the technique to achieve the design data voluntarily passes on and classification and renewal; Convenient consumer administer and protection system。The combination of software and AutoCAD, can largely simplify the field of AutoCAD in mechanical drawing and design process, greatly improve work efficiency and resource use efficiency. As an indispensable "standard data" in the process of Mechanical design, without exception, according to certain principles, to comply with certain principles of mechanical design to select, therefore, this combination of software and AutoCAD, can provide adequate help and facilitate to designers, has great market value.
