Hello gentlemen, I'm kind of new to this group,and while I notice a lot of non machining talk I'm hoping to get a bit of help. A little back history may help, I have been machining for 30 plus years, small shops and a lot of prototype works,recently I have been doing some odd jobs on an old Haas VF0 I have in my garage,mainly pocket money type stuff. The place I'm working for is starting to go under so I'm thinking it might be a good time to go out on my own, I have a few leads to pickup some work. The main question I have now is how to go about accurately quoting prices,my garage stuff seems to come up a little short sometimes,considering the amount of non-machining time that goes into parts, the basic cost I seem to have like cycle time ,material cost and such,but I am having difficulty in what I call the stuff around the edges.The time it takes to order material and write up invoices,material handling, stuff like that. If I get to a place when I need office staff and other people that are needed but don't actually machine parts, their costs need to be part of the cost and have to go in the the unit cost of the parts I'm making. The question is basically how do you calculate those costs,is there a formula or something that you use, like cycle time x hourly rate x 1.5 or something. any help would be welcome Bill
