Once during a gain share exercise with an aerospace company we calculated that their centralized tool crib to issue and change cutting tools added 20% to the true tool cost for this facility (one location, not a definitive study). We have also had to wait extra days because vending machines ran out of the tools we were onsite to test. The reasons for this are in a prior article: https://goo.gl/h6rDKX
Now, what if you had a mini-vending unit that dispensed only the consumable cutting tools for that machine or cell? Maybe it would be a portable electronic tool box that the machinist picked up at the crib before each shift (I saw a concept of something like this in the UK, don't know if it ever made it to market). What if it could capture not just the units, a time and date stamp, but also the current part count when the tool or inserts were changed? Below is the kind of actionable data that you could calculate if you added just this one more piece of information.
