چکیده

A parting line for a convex polyhedron, P, is a closed curve on the surface of P. It deenes the two pieces of P for which mold-halves must be made. An undercut-free parting line is one which does not create recesses or projections in P and thus allows easy de-molding of P. Computing an undercut-free parting line that is as at as possible is an important problem in mold design. In this paper, an O(n 2)-time algorithm is presented to compute such a line, according to a prescribed atness criterion, where n is the number of vertices in P.

Computing a Flattest, Undercut-Free Parting Line for a Convex Polyhedron, with Application to Mold Design

A parting line for a polyhedron is a closed curve on its surface, which identiies the two halves of the polyhedron for which mold-boxes must be made. A parting line is undercut-free if the two halves that it generates do not contain facets that obstruct the de-molding of the polyhedron. Computing an undercut-free parting line that is as \\at" as possible is an important problem in mold design. ...

Determining Moldability and Parting Directions for Polygons with Curved Edges

We consider the problem of whether a given geometry can be molded in a two part, rigid, reusable mold with opposite removal directions. We describe an efficient algorithm for solving the opposite direction moldability problem for a 2D “polygon” bounded by edges that may be either straight or curved. We introduce a structure, the normal graph of the polygon, that represents the range of normals ...

Automatic generation of mold-piece regions and parting curves for complex CAD models in multi-piece mold design

Multi-piece molding technology is an important tool in producing complex-shaped parts that cannot be made by traditional two-piece molds. However, designing multi-piece molds is also a time-consuming task. This paper proposes an approach for automatic recognition ofmold-piece regions and parting curves for free-form CAD models. Based on the geometric properties of objects and mathematical condi...
