Impertinent heat treatment can influence die and mould manufacturing such as over— hard and— soft and assembly． Traditionally the heat treatment process was made out according to the methods and properties brought forward by designer． This could make the designers of die and mould and heat treatment diverge from each other， for the designers of die and mould could not fully realize heat treatment process and materials properties，and contrarily the designers 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,which 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 10 process ， so that the former mistakes are easily spread backwards． Meanwhile， 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 progress of die and mould and have close intermunion with purchasers． This is propitious to elimination of the conflicts between departments， increase the efficiency and reduce the 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． 11 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 treatm
