The Selection and Prospect of CAD/CAM System for Diesel Engine Design and Manufacturing

Abstract

It is highly necessary to use the CAD/CAM system in machine design and manufacturing because it will help the designer to modify the design method and thus promote productivity. According to traditional design method, the first step is the projective design; the second step is the detail design; then the last step — where the technology of machine components are considered — the manufacturing design. Furthermore, the prototypes of a machine are built, tested, and refined until the technical assignment is satisfied. To execute this design method, a long time is needed and it is too expensive to build the prototype of the machine and to carry on the testing process. Now the design — refine cycles are carried on in the CAD system partly to replace the pure prototype — testing cycles that can save vast amounts of money, and will reduce the period of design and manufacturing.
