【正文】 ny models fit the test nicely， but they cannot be put into practice． Difficulties with most of models are solved in analytic solution， and numerical method is employed so that the inaccuracy of calculation exists． Even so， paring experience method with quali tative analysis， heat treatment simulation by puter makes great progress． 6 Establishment and integration of models The development procedure for die and mould involves design,manufacture， heat treatment， assembly， maintenance and so on． They should have ow n database and mode1． They are in series with each other by the entity— relation model． Through establishing and e mploying dynamic inference mechanism ， the aim of optimizing design can be achieved． The relation between product model and other models was built． The product model will change in case the cell model changes． In fact， it belongs to the relation of data with die and mould． After heat treatment model is integrated into the system， it is no more an isolated unit but a member w hich is close to other models in the system． After searching， calculating and reasoni ng from the heat treatment database,procedure for heat treatment， w hich is restricted by geometric model,manufacture model for die and mould and by cost and property， is obtained． If the restriction is disobeyed， the system will send out the interpretative warning． All design cells are connected by munication work． Management and harmony among members The plexity of die and mould requires closely cooperating among 7 item groups． Because each member is short of global consideration for die and mould development， they need to be managed and harmonized． Firstly,each item group should define its ow n control condition and resource requested,and learn of the request of upanddow n working procedure in order to avoid conflict． Secondly， development plan should be made out and monitor mechanism should be established． The obstruction can be duly excluded in case the development is hindered． Agile management and harmony redound to municating information， increasing efficiency， and reducing redundancy． Meanw hile it is beneficial for exciting creativity， clearing conflict and making the best of resource． 4 Conclusions (1) Heat treatment CAD／ CAE has been integrated into concurrent design for die and mould and heat treatment is graphed,which can increase efficiency， easily discover problems and clear conflicts． (2) Die and mould development is performed on the same platform． When the heat treatment process is made out， designers can obtain correlative information and transfer selfinformation to other design departments on the platform． (3) Making out correct development schedule and adj usting it in time can enormously shorten the development period and reduce cost． References： [1] ZHOU Xionghui， PENG Yinghong． The Theory and Technique of Modern Die and Mould Design and Manufacture[M]． Shanghai： Shanghai Jiaotong University Press 2020(in Chinese)． [2] Kang M， Parkamp。Heat Treatment of Die and Mould Oriented Concurrent Design LI Xiong,ZHANG Hongbing,RUAN Xue— yu,LUO Zhong— hua,ZHANG Yan Abstract: Many disadvantages exist in the traditional die design method which belongs to serial pattern. It is well known that heat treatment is highly i
