This process provides the following setup options:

Determines how aPriori calculates the number of parts per machine batch, that is, the number of parts processed in one machine cycle. The default method is specified by the cost model variable defaultPartLoadingMethod (Part Projected Area in starting point VPEs). Users can override the default with this setup option. Choose one of the following:

See Number of Parts for Hot Isostatic Pressing for detailed information.

Specifies the number of parts per machine batch, that is, the number of parts processed in one machine cycle. By default this is determined as described in Number of Parts for Hot Isostatic Pressing. You can override the default with this setup option.

Specifies the time (in minutes) to fill the vessel with the inert, process gas, and equalize vessel pressure with the pressure in the gas inlet lines (see Cycle Time Formulas for Hot Isostatic Pressing). By default, this is specified by the cost model variable vacuumPurgeEqualize (9 minutes in starting point VPEs). You can override the default with this setup option.

Specifies the time (in minutes) required to bring the vessel to the required hold pressure (see Cycle Time Formulas for Hot Isostatic Pressing). By default, this is specified by the cost model variable pressurizingVesselTime (40 minutes in starting point VPEs). You can override the default with this setup option.

Specifies the rate (in degrees Celsius per minute) at which the temperature in the hot zone is ramped up to the hold temperature (see Cycle Time Formulas for Hot Isostatic Pressing). By default, this is looked up by material type in the lookup table tblMaterialTypeProperties. If the material type is not found, default heating rate is given by the cost model variable averageHeatingRate (7.2°C per minute, in starting point VPEs). You can override the default with this setup option.

Specifies the time (in hours) required to ramp up the temperature in the hot zone to the hold temperature (see Cycle Time Formulas for Hot Isostatic Pressing). By default, this is based on the heating rate and the difference between the ambient temperature and the hold temperature. You can override the default with this setup option.

Specifies the pressure (in MPa) in the hot zone during the hold phase of the machine cycle. This is used to calculate gas cost—see Process Gas Cost for Hot Isostatic Pressing. By default, this is specified by the cost model variable hipDefaultHoldPressure (100 MPa in starting point VPEs). You can override the default with this setup option.

Specifies the duration (in hours) of the hold phase of the machine cycle, during which parts are held at high pressure and temperature (see Cycle Time Formulas for Hot Isostatic Pressing). By default, this is looked up by material type in the lookup table tblMaterialTypeProperties. If the material type is not found, default hold time is given by the cost model variable averageHoldTime (2.6 hours in starting point VPEs). Users can override the default with this setup option.

Specifies the rate (in degrees Celsius per minute) at which the hot zone is cooled down from the hold temperature to the ambient temperature (see Cycle Time Formulas for Hot Isostatic Pressing). By default, this is looked up by material type in the lookup table tblMaterialTypeProperties. If the material type is not found, default cooling rate is given by the cost model variable averageCoolingRate (13.3°C per minute, in starting point VPEs). You can override the default with this setup option.

Specifies the time (in hours) required to cool down the hot zone from the hold temperature to the ambient temperature (see Cycle Time Formulas for Hot Isostatic Pressing). By default, this is based on the cool rate and the difference between the ambient temperature and the hold temperature. You can override the default with this setup option.

Specifies the number of operators racking or wiring up parts to be placed in the heat treatment furnace (see Labor and Setup Costs for Hot Isostatic Pressing). By default, this is looked up by weight in the lookup table tblHandlingTimes. You can override the default with the setup option

Specifies the fraction of gas from one machine cycle that is recycled and used in the next machine cycle. This is used to calculate gas cost—see Process Gas Cost for Hot Isostatic Pressing. By default, this is specified by the cost model variable hipDefaultGasReusePercentage (in starting point VPEs this is 0.95--that is, 95% of the gas is reused). You can override the default with the setup option.
