Setup Operation Options
For most machining processes, aPriori automatically computes the number of part setups, or specific orientations that the part must be placed in, that are required to perform the assigned operations on that machine. For more information, see
Working with Part Setups and SetupAxis GCDs. You can provide additional information about part setups using the following process options:
• Repetitions of part setup: number of repetitions of the setup procedure for each orientation. By default, aPriori assumes that a part is setup only once in each orientation. However, you can use this option to override this assumption and specify if the part is actually setup multiple times in a given orientation. This may occur, for example, if the routing sheet indicates that some features of the part are machined, then the part is removed for inspection of the feature, and then placed back on the machine in the same orientation to machine additional features. Use the following option:
o Default Repetitions of Part Setup: the value of the cost model variable repetitionsOfPartSetup, which is 1 in aPriori basleines.
o Override Repetitions of Part Setup: enter a positive whole number, the number of times the setup procedure is performed for the current part orientation.
• Total setup time: time to perform a single given setup. By default, aPriori computes the time required for each part setup based on the part weight, including the time for cleaning, loading, clamping and orienting the part. This process setup option allows you to override the time required for the specified setup.
To override the amount of time required for a specific setup, expand the manufacturing process of interest (e.g., 3-Axis Mill), right-click on the Setup node of interest, and select Process Setup Options.
