If machining processes are included as secondary processes on bar and tube components, then the machining costs are computed via the Machining cost model and combined with the Bar&Tube process costs to produce a total manufacturing process cost.
This section details how costs are calculated by aPriori. Note that you can override the calculation of many of the quantities involved, and specify them explicitly—see
User Inputs, below.
When not otherwise specified, costs are per part.
