HI Guys,
I'm putting in inventory software that'll help generate 'cost to produce' info that should be better than my excel sheet from hell.
This leaves me with a puzzlement: how to price time in the tumbler, or other automatic gear? (Not the CNC's.)
When the tumbler's running, it eats power, water, and abrasive. All of those I can more-or-less account for, at least in a general way. The real question is time.
I have a shop rate of "X" per hour to cover power/lights/people/paperclips, etc.
But when I've got parts in the tumbler, nobody's actually paying any attention to it, or 'working' it, except every so often to check the parts, or to load/unload, and that's reasonably quick.
So would you cost it out at shop rate *plus* abrasives/power/water, etc, or some smaller fraction of shop rate plus consumables, to reflect the fact that nobody's making it their prime mission, and they're all doing other stuff?
Thoughts?
Brian
