Choosing between a manual tool change and a pallet system for a 50-part run

Everyone said the pallet system was the only way to go for speed. I stuck with manual changes and finished the job in 8 hours, same as the quote. The extra setup time for the pallets would have eaten the profit. When do you guys decide a pallet system is actually worth it?

Read a case study where a shop only broke even on pallets after 200 identical parts. The math is brutal for short runs. It's not just the hardware cost, but programming time and proving out the first part on multiple fixtures. That setup eats hours you don't get back. For a 50-piece run, manual is almost always faster unless the part is crazy complex and needs hours of machine time per piece.

Yeah, that's the real math right there... totally agree with what hollyscott said about the setup hours. Had a similar 60-piece job last month. The pallet system looked good on paper, but just clocking all those fixtures and writing the extra code would have taken a full day. The manual changes were boring, but for a simple part like that, it was just load, hit go, repeat. The profit is in that first part setup, not in shaving thirty seconds off each cycle. Pallets only make sense for me when the machine run time per part is so long that you can set up the next one while it's cutting.

Look at it from the other side though. What @hollyscott calls setup hours, I call an investment. You do that work once and then you can run the same job again anytime with almost no setup. That boring manual change for sixty parts is sixty chances for a tired operator to make a mistake. A pallet system locks in the setup perfectly every time. The profit isn't just in the first part, it's in making the whole run foolproof and getting the machine cutting while you're doing something else.
