Been running in batch mode this week after work machining multiples of the various brackets and parts. There's the 1/2" setup.
Machining process optimization occurs when I cut stuff in batches. Tweaks to depth of cut, speeds/feeds, and even attempts to figure out how to fixture multiples in 2 vises. By the time I'm done, I've usually figured out the most optimal way.

An example is illustrated below: I've figured out how to fixture and machine the base slot machining process with 3 per vise. This optimizes setup time, reduces tooling changes, and increases the amount of machining that can be done unattended in a single operation.
Sometimes I also refine the design. In this case, I noticed that the 1/4" brackets, when loaded with extensions, had enough space below to allow for a second level of extensions.
By a few simple tweaks to the machining process I was able to quickly test the idea during the run to see if it was viable or not. I think, in this case, the idea makes a lot of sense. Will need a completed one before I can say if accessing an extension beneath another is cumbersome or not.
