Batch Setup Time

For machining processes other than milling and turning processes, time to set up a production batch is generally based on the machine property Setup Time.

For milling and turning processes, time to set up a production batch is based, by default, on a number of factors, including the following:

• Time to install workholder (0 by default, but see the PSO Install Workholder in Machining Process-level Options)

• Cleanup time (0 by default, but see the PSO Cleanup Time in Machining Process-level Options)

• Number of tools used by all operations in the current process (see Tool Selection for Machining)

• Number of part setups (see Working with Part Setups and SetupAxis GCDs)

• Cycle time (see Process Cycle Time: this is excluded by default. You can include some fraction or multiple of cycle time by setting the cost model variable firstRunPenaltyFactor (0 in starting point Digital Factories).

Note: If you set firstRunPenaltyFactor to 1, batch setup time is assumed to include time to mill or turn one pallet’s worth of parts (there is one part per pallet by default, but see the PSO Parts in Pallet in Machining Process-level Options). This is intended to guard against the risk of scrapping the first pieces in a production run. It is why cycle time is listed above as a potential factor affecting batch setup time.

You can override this calculation, and specify batch setup time explicitly with the PSO Batch Setup Time; see Machining Process-level Options.
