Jan 01, 2012 For example, as opposed to turning, which can be readily modeled in two dimensions, the 3-D nature of grinding makes calculating chip thickness difficult. Machine operators accustomed to the speeds-and-feeds diagrams used for turning are frustrated that such a relationship does not exist for grinding.

3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for 60 per hour - including all fuel and other costs - and you excavated 100 cubic meters per hour, your unit cost for excavation would be 0.60 per cubic meter.
