Design-CAD File Part Details and Tooling Part 6

Description

The last time I wrote an article for Design Corner was in November of 2007. That was quite a while ago. As promised in the closing statement of the July/August publication of Design Corner, this issue will address draft, undercuts parting lines and other features that should be included in 3D CAD models for rotational molding. The majority of patterns and molds fabricated today are machined directly from a 3D CAD file provided by the designer. The tool maker typically makes little to no changes to the file with the exception of adding draft and a few features for mold fabrication. Therefore the designer must be extremely careful to include all the proper features to mold a quality part. The remainder of this article will review the importance of draft, undercuts and parting line location in the CAD file.
