【正文】 ws you to draw a model on screen, then view it from every angle using 3D animation and, finally, to test it by introducing various parameters into the digital simulation models(pressure, temperature, impact, etc.) CAM, on the other hand, allows you to control the manufacturing quality. The advantages of these puter technologies are legion: shorter design times(modifications can be made at the speed of the puter),lower cost, faster manufacturing, etc. This new approach also allows shorter production runs, and to make lastminute changes to the mould for a particular part. Finally, also, these new processes can be used to make plex parts. ComputerAided Design(CAD)of Mould Traditionally, the creation of drawings of mould tools has been a timeconsuming task that is not part of the creative process. Drawings are an anizational necessity rather than a desired part of the process. ComputerAided Design(CAD) means using the puter and peripheral devices to simplify and enhance the design process .CAD systems offer an efficient means of design, and can be used to create inspection programs when used in conjunction with coordinate measuring machines and other inspection equipment .CAD data also can play a critical role in selecting process sequence. A CAD system consists of three basic ponents: hardware, software, users. The hardware ponents of a typical CAD system include a processor, a system display, a keyboard, a digitizer, and a plotter. The software ponent of a CAD system consists of the programs which allow it to perform design and drafting functions. The user is the tool designer who uses the hardware and software to perform the design process. Based on the 3D data of the product, the core and cavity have to be designed first. Usually the designer begins with a preliminary part design, which means the work around the core and the cavity could change. Modern CAD systems can support this with calculating a split line for a defined draft direction, splitting the part in the core and cavity side and generating the runoff or shutoff surfaces. After the calculation of the optimal draft of the part, the position and direction of the cavity, slides and inserts have to be def
