In Machining, a Lathe that changes tools is great but on small parts that have several quick operations there can be more tool change time than spindle-on machining time. A great way to increase spindle-on time and reduce overall cycle time is to tie several tools together in a method known as "gang tooling." Gang tooling planning is very difficult as you need to anticipate the following operations while working on the current one. At Lean Machine, we always go further than most with 3D design because it always pays off in the long run. Since we already have our machines 3D modelled and we can download all tooling off our vendor's website, and every part is drawn in 3D, we can plan out a gang tool very quickly.
