Machine Selection

The following sections describe machine selection:

Turret Press Machine Selection

For Turret Press, aPriori selects the default machine if it is feasible; otherwise, aPriori selects the feasible machine with the lowest overhead (specified by the sum of the machine properties Direct Overhead Rate and Indirect Overhead Rate).

The machine feasibility rules for turret press require that the machine can accommodate at least the blank for a single part:

• PSO Stock Sheet Width must not exceed the machine property Max Sheet Width.

• PSO Stock Sheet Length must not exceed the machine property Max Sheet Length.

• PSO Thickness of Part must not exceed the machine property corresponding to the part’s material type:

o Max Sheet Thickness Steel

o Max Sheet Thickness Aluminum

o Max Sheet Thickness Brass

o Max Sheet Thickness Stainless Steel

o Max Sheet Thickness Copper

Bend Brake Machine Selection

For Bend Brake, machines are prioritized as follows:

• aPriori selects a feasible machine that can accommodate the length of the part’s bends, if such a machine exists. A machine can accommodate the part’s bends if and only if the PSO Maximum Bend Length does not exceed the machine property Max Bend Length.

• If no such machine exists, aPriori selects the default machine, if it is feasible.

• If the default machine is not feasible, aPriori selects the feasible machine with the lowest overhead (specified by the sum of the machine properties Direct Overhead Rate and Indirect Overhead Rate).

The machine feasibility rules for bend brake require that the machine can accommodate stock sheet thickness as well as the radii (relative to sheet thickness) of the part’s bends:
