CA/CAM/CNC Application To Manufacture The Mold

Abstract

Nowadays, the application of CAD / CAM / CNC is becoming more and more popular, leading to the technical requirements of using computers to use design software and fully apply the capabilities of CNC machines to Machining details that need high precision. Based on the requirements that society has in the field of precision mechanical processing, this thesis studies the application of CAD/CAM software, CREO in particular to the design and machining of high precision molds by CNC 5-axes machine that traditional machines can hardly perform. A case study is produce helmet shell mold which is a most important part in a helmet structure. The thesis has based on the average height of Vietnamese people to make a standard head circumstance to design and process helmet casting molds suitable for the majority of Vietnamese people. Haas UMC 750 5-axis milling machine will process products in order to serve research. However, there are some limitations in the machining process as the product requires special machining tools.
