A Little CNC

Walt runs the CNC mills and lathes for Arisaka. One of the toughest parts of designing a new part is understanding how to be efficient in terms of manufacturing. This means reducing the number of operations and the number of tool changes to go from a block of aluminum (or some other material), to the final part.

As an example, here are two pictures of the Inline Scout Mount for KeyMod handguards. Cutting this part requires two operations. The first picture shows how the mounts look after the initial operation. Notice that only the top has been cut, and there's still the remaining block of aluminum attached to the bottom. The part is then flipped over and the final operation is performed, resulting in the second picture.
