This Setup is Super Lean! Here portrayed is a tombstone where all 4 sides are used to best advantage. For this lean solution, maximum attention is focused on using the limited "acreage" of the tombstone to do the most possible in the least amount of space. As can be seen, at least 3 different parts will be machined on this tombstone in a horizontal machining cell. It is set up so that 2 identical tooling setups are used: one of the setups is "in process" i.e. cutting, and the other setup is out for part loading/unloading or clamp changes. The tooling setup is unique in that there are no intermediate clamp changes for any of the processes. The pictures try to portray how each of the parts is located and held throughout the process all at once. With this setup, the parts are machined complete in one machining cycle. In other words, once you go through 1 cycle, every cycle thereafter, 2 or 4 or 6 parts (depending on which part is on the tombstone) come off complete.
- All the parts can be machined using the same tooling.
- The tooling is very compact thanks to the tiny "footprint" of the Invert-A-Bolt™ fasteners.
- Obstructions to the machining have been minimized/eliminated since the Invert-A-Bolt™ fasteners are below the surface of the riser.
- No intermediate clamp changes are required.
- Parts are machined at optimum speeds--this is a super stable setup.
- By designing the tooling this way, there are no intermediate clamp changes required to complete the parts. The only time the pallet is out is for moving the in-process parts to another position.
- Common tooling maximizes the capital investment.
- Common cutters are used to machine sides 1 and 2 of each of the parts. This efficient use of the cutters is acheived by the unique tooling setup.
