“The molds we make are solid models,” Asbury said. “I brought them into GibbsCAM Solid Surfacer, which I had never used before, and by playing with it, I fi gured out how to generate toolpath the way I felt was optimal for machining.
It’s easy, and if I have a new situation that I can’t fi gure out in a few minutes, I call our GibbsCAM Reseller, who responds quickly. If he’s out of town, I contact Gibbs tech support. In my fi ve years here, I’ve used them twice.”
The moment you realize that new requirements do not require new equipment. This is the moment we work for.

Delkron engine production continued uninterrupted while the Delkron project team developed the bill of materials for the engines, began CAD model- ing, and developed a strategy to bring components in house. With all new parts, Asbury determines how to make workholding economically and quickly. He uses both SolidWorks and GibbsCAM for modeling, depending on whether he needs models quickly, only for use by his group. For quick restricted use, he uses GibbsCAM. If other departments will use the models, he makes it more convenient for them by using SolidWorks.
Having both contact and optical scanning technology allows the new O-INSPECT 322 to do the work of a CMM, a microscope, a profile projector, and a contour measuring instrument. One machine for your inspection needs.

GibbsCAM has many design features to add or subtract features from solid models, or to create wireframe or solid models for machining. “It all depends on what I need and prefer for a specifi c job,” said Asbury. “Often, when I’m programming, I’ll just take a wireframe surface off a solid, because it’s a quick and easy way to generate position points and other geometry.” The fi rst Delkron components to be made were rocker boxes (valve covers), which begin as two pieces of 6061-T6 aluminum billet, one for the bottom to accommodate valves and springs, and one for the cover. Asbury determined these would be made in two setups each for three-axis machining on the Haas VF-3, and that a fi xture would need to be machined fi rst. Using the fi xture, he machines the outside and inside of the bottom piece, and completes drilling and tapping on that side. Using the machined holes and pockets for holding the fl ipped part, he fi nishes the bottom to size, and machines remaining features. Parts are
