【正文】 rarely understood the service environment and designing thought. These divergences will impact the progress of die and mould to a great extent. Accordingly， if the process design of heat treatment is considered in the early designing stage， the aims of shortening development period， reducing cost and stabilizing quality will be achieved and the sublimation of development pattern from serial to concurrent will be realized． Concurrent engineering takes puter integration system as a carrier ,at the very start subsequent each stage and factors have been considered such as manufacturing， heat treating， properties and so forth in order to avoid the error． The concurrent pattern has dismissed the defect of serial pattern,w hich bring about a revolution against serial pattern． In the present work． the heat treatment was integrated into the concurrent circumstance of the die and mould development ， and the systemic and profound research was performed． 1 Heat Treatment Under Concurrent Circumstance The concurrent pattern differs ultimately from the serial pattern(see Fig． 1).With regard to serial pattern， the designers mostly consider the structure and function of die and mould， yet hardly consider the consequent process， so that the former mistakes are easily spread backwards ． Meanw hile，the design department rarely municates with the assembling ， cost accounting and sales departments． These problems certainly will influence the development progress of die and mould and the market foreground ． Whereas in the concurrent pattern， the relations among departments are close， the related departments all take part in the development pro gress of die and mould and have close intermunion with purchasers． This is propitious to elimination of the conflicts between departments， increase the efficiency and re duce the 2 cost． Heat treatment process in the concurrent circumstance is made out not after blueprint and workpiece taken but during die and mould designing． In this way， it is favorable to optimizing the heat treatment process and making full use of the potential of the materials． 2 Integration of Heat Treatment CAD／ CAE for Die and Mould It can be seen from Fig． 2 that the process design and simulation of heat treatment are the core of integration frame． After information input via product design module and heat treatment process generated via heat treatment CAD and heat treatment CAE module will automatically divide the mesh for parts drawing， simulation temperature field microstruc ture analysis after heat— treatment and the de fect of possible e merging (such as overheat,over burning)， and then the heat treatment process is judged if the optimization is made according to the result reappeared by stereoscopic vision technology． Moreover tool and clamping apparatus CAD and CAM are 3 integrated into this system． The concurrent engineering based integration frame can share information with other branch． That makes for optimizing the heat treatment process and ensuring the process sound． 3D model and stereoscopic vision technology for heat treatment The problems about materials， structure and size for die and mould can be discovered as soon as possible by 3D model for heat treatment
