Abstract:

This paper describes the evaluation and acquisition of CADCAM technology required for the design and development of complex sculptured surfaces for molding rubber and elastomeric materials. Benchmark tests incorporating the complex 3-D geometry that such a design project must handle were performed with various systems vendors and a time-sharing system was chosen. Geometry was constructed using bi-parametric cubic patches and cutter paths were plotted over these surfaces. A post-processor has been prepared for a three-axis numerical control milling machine and a cavity cut to vacuum-form a thermoplastic rubber for a prototype. Keywords Human factors engineering Anthropometric data CADDComputer Aided Design and Drafting French language and Numerical code programming.
