Country music legend Willie Nelson is credited with saying, “The early bird gets the worm, but the second mouse gets the cheese." It’s unlikely that Willie was reflecting on manufacturing. Regardless, his quote still summarizes perfectly one of the greatest challenges sheet metal fabricators face: When nesting, is it better to be early, or just in time?

Matot, a small dumbwaiter manufacturer in the Chicago suburbs, is a microcosm of high-product-mix, low-volume manufacturing. Fabricators no longer make it work on the floor. Instead, they adjust the model to suit the process.

Advancements in nesting software development have made a real impact in terms of increased material utilization and machine uptime, but for a fabricator to get the most out of the nesting software, it needs to be fully integrated with the design and shop management software systems.

The speed of fabricating is increasing at a rapid pace, but the press brake remains a bottleneck for many companies. Laser cutting and punching machines can run unattended if necessary without the need to program a robot, but the same can't be said for a press brake. Human operators still are pretty much a necessity. Advancements in bending software, however, can help to streamline the bending process. Fabricators only need to give it a try.
Hard tooling for traditional fixtures often depends on costly milling and other non-sheet metal processes. So how can these costs be minimized? The simple answer is to marry the processes and machinery you already have--including laser cutting, waterjet cutting, and punching--to the appropriate CAD system.

It sounds like a no-brainer in electronically connected world, but shops don't have the ability to integrate their 3-D modeling capabilities with nest creation. As more shops jump into 3-D modeling with the goal of decreasing turnaround time for jobs, they are looking at a more formal connection between the design and production world.

Doug Bergeson of Bergeson Technology, Dawson, Minn., saw the carnage that improvised explosive devices caused in Iraq, so when he came on, he worked on a solution. He has one now and wants others to know about it.

Among the tools in the 3-D CAD toolkit—extrudes, revolves, sweeps, and lofts—the first two can be used to create identical parts, but they don't work the same way. Depending on which process you choose, the time the computer needs to model and rebuild the part can vary substantially.

Columnist Gerald Davis explains that preparing a 3-D CAD model without dimensions may look great, but it doesn't really do anybody any good. For example, a 3-D CAD model with dimensions helps quality control inspectors.
