Three Dimensional Design and Unfolding Method of Sheet Metal Parts

Abstract

Sheet metal parts are widely used in various fields of mechanical industry. Unfolding is the first process of sheet metal processing. Due to the traditional manual way of sheet metal parts with large labor intensity and low efficiency, so the mode of production of sheet metal parts must be improved for quality and efficiency. Along with the conditions of computer aided design and production needs of the sheet metal industry, sheet metal CAD system is proposed to establish. At present, sheet metal systems are mostly based on second development of three-dimensional software to set up. So this paper is based on UG for second development to establish the sheet metal system. This system concentrates the study of method of parameter design and automatic unfolding of sheet metal parts. Parametric design and unfolding model of sheet metal parts is accomplished through the establishment of unfolding model and write control program. The principles of parametric design and second development tools of UG are specifically discussed in this paper. Unfolding model is created through the establishment of the parameters and considering plate thickness.
