Abstract: The objective of this thesis was to apply a CAD/CAE/CAM softwarein making the injection mold. The overall process consists of the followingsteps. The object was first designed using the CAD software and its propertieswere analyzed under various injection conditions. The computation was carriedout using a finite element technique and the results were presented usingcomputer graphics. The distribution of temperature, pressure and stress wererepresented by colors. The mold was made using a CNC machine coupled witha CAD/CAE/CAM software. The mold was used to produce the object. Finally,the properties of the object were compared with those predicted from thecomputation to test the validity of the simulation.The CAD/CAE/CAM software, STRIM 100, from CISIGRAPH Co.,Ltd., was chosen in this study. This software is currently used in variousindustrialized countries all over the world. Since the CAD/CAE/CAM is anexpensive technology, it would be of benefit if the software could be used atremote distance. In this work the possibilities of data transfer and the use ofCAD/CAE/CAM software via modem were therefore investigated. It was foundthat the rates of data transfer between workstation and PC through high-speedmodem (14400 bps) are 160 byte&c and 264 bytes/set for binary data andASCII data, respectively. The rate of data transfer among work stations throughintemet system is 536 bytes/set. Although many of the file operations can beperformed at remote distance, the CAD/CAM software can not be employedefficiently.The results from this research are summarized as follows. The use ofa CNC machine coupled with a CAD/CAE/CAM software has advantages overthe conventional practice in many aspects. For examples, each part of themold can be made independently. The compensation for shrinkage can bereadily estimated. The molds designed by a CAD/CAE/CAM software havemore accuracy in dimension than those produced by the conventional method.The use of CAE software in the analysis of the plastic flow in order to specifythe flow direction and the gate position is beneficial to the design stage. Theanalysis of residual stress is inconclusive in this work, however.
