Application of three-dimensional parametric modelling in the mould working for air intake hose

This paper deals with an application on the mould machining of air intake hose product by using 3-dimensional parametric modelling techniques. The detailed domain is the 3-dimensional product with similar shapes and different sizes which needs too much working time for preparation of modelling or machining due to making a trial and errors repeatedly. Decision making rules for selection of modelling order and technique, and for calculation of cutting conditions, and for determination of sequence and method concerning machining operations are required by interview of expert engineers in the field. The developed expert system of modelling and machining is programmed by using a user programming language under the CAD/CAM software of the Personal Designer. The developed system that aids a mould engineer who is working in the modelling and machining section which deal with air intake hose product provides strong and useful capabilities.
