Trimming: Oper. Conds Tab

Variable Definitions, Ranges and Default Values

The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

Variable	Default Value	Range

● Unprocessed Entity Name	Entity Name Unknown	Any Text
○ Reammed / Trimmed Entity Name	Trimmed Entity	Any Text
○ Material Removed (kg per part)	0.0	Positive
● Operating Throughput per Unit (trimmed (or reammed) entities/h)	0.0	Positive
○ Setup Time The amount of time (per cycle) spent before each operation is carried in preparation for the actual execution of the operation. It may involve actions like cleaning, vacuuming, setting up of equipment, etc. which the user opted not to model explicitly.	0.0	Positive
◙ Process Time The actual duration of the operation (per cycle).	60.0	Positive
○ Ignore Labor? Check this box to ignore labor for this operation. This option is used only if the process time is set by a master-slave relationship.	Yes	Yes/No

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see Trimming: Modeling Calculations.

•Operating Throughput...

The operating Throughput variable is calculated by the program.

•Duration Options...

The duration controls appear only if the procedure is in batch mode. In Rating Mode, you can set the process time (and the setup time), allow the process time to be calculated (based on the throughput), or allow the duration to match exactly the duration of another operation either in the same procedure or in another procedure. In Design mode, you must either specify the process time (and the setup time) or allow the duration to match exactly the duration of another operation (either in the same procedure or in another procedure).

If you choose to match the duration of this operation with the duration of another operation, you introduce a master-slave relationship between the two operations. The program will match the setup-time, the process time and the turnaround time of this operation (the ‘slave’) with the corresponding times of the reference operation (the ‘master’ operation). For more on master-slave relationship, see The Scheduling Tab.
