This machine, a five-axis VMC, was designed with multiple pallets. Because VBI specializes in repeat orders for complex aerospace components, Mr. O’Rell needed a system that would allow him to set up a fully fixtured pallet dedicated to each job and then store the fixture pallets for immediate use whenever the job repeats.

The fixtures had to be affordable because he needed a lot of them. They had to provide rigid clamping without distorting the workpiece. They had to allow quick loading and unloading of the parts to keep setup time within the targets demanded by lean manufacturing. The fixtures had to get the workpieces away from the surface of the pallet so the spindle could reach all exposed faces of the workpiece for five-axis machining without interference. Finally, they had to minimize the clamping stock required in workpiece blanks to reduce material waste."
