All you engineers are funny! As a business owner and a machinist, the most difficult task I’ve ever had is teaching an engineer that giving the customer what they ask for or want AND being nice about it matters. On a daily basis, machining parts to the prints some engineers put out and finding out that a .0001” tolerance on a surface fits AIR is frustrating. What only the accountants and project managers seem to understand is that the tolerance decimal point and the price decimal point are inversely correlated!
