The combined application of these two softwares can improve molds design and its NC machinings quality and efficiency. This paper expatiates the method and main techniques to proceed the molds design of the Digital camera cover-panel with the Pro/ENGINEER software, then convert the graphics data to MasterCAM software to proceed the NC programme, and apply the MasterCAM software to create the NC machining code and transport it to the control system of the NC machining center or the NC milling machine for processing.Through design the jet mould, I has grasped the main step of the correlation mold designs, and also has the further enhancement on the CAD/CAM software application.
