This 15-5 PH stainless steel aircraft part measures 4.0 x 4.5 x 6.5 inches and was manufactured on an HMC. It requires four separate operations and has a total cycle time of 3 hours and 45 minutes.

This aluminum test plate measures 0.56 x 3.26 x 4.68 inches and contains more than 5,000 individual dimensions that were programmed without CAD/CAM. The part is produced on a VMC with a cycle time of 5 hours and 30 minutes.

Hommer's collapsible mold for injection molding does not use a rotating core. This results in increased speed and reduced cycle time. the mold, which requires a tolerance of 0.002 inch, was manufactured using a CNC lathe and multi-axis turning center. It is machined from A2 tool steel.

Produced for Harley Davidson, this 6061-T6 aluminum air intake component is designed to create performance-enhancing air flow. The part requires accuracy of 0.005 inch and is manufactured on a VMC.
