• Sand Additive Type: This PSO is defined for the moldmaking and coremaking processes, and allows you to select from among the additive types specified in the lookup table tblSandAdditives. The default additive type is None, which indicates that no additive is used.

• Sand Additive Percent: This PSO is defined for the moldmaking and coremaking processes, and allows you to enter the percentage of sand that should consist of additive. The default additive percentage is specified in the entry for the current additive type in the lookup table tblSandAdditives. The default additive type is None, which indicates that no additive is used. See also the PSO Sand Additive Type.

• Sand Additive Rate: This PSO is defined for the moldmaking and coremaking processes, and allows you to enter the additive cost per unit mass. The default additive rate is specified in the entry for the current additive type in the lookup table tblSandAdditives. The default additive type is None, which indicates that no additive is used. See also the PSO Sand Additive Type.

• Core Cost: This PSO is defined for GCDs for which coremaking is performed. You can override the core cost calculated by aPriori, and specify a value explicitly.

• Corebox Cavity Calculation Mode: This PSO is defined on the Casting—Sand node. If this is set to Opportunistic (the default setting in starting point VPEs), the number of corebox cavities is the maximum number of cavities that will fit along the length direction of the coremaking machine. If set to Single Cavity, the number of corebox cavities is 1. The default setting is specified by the cost model variable coreboxCalcMode (Opportunistic in starting point VPEs). See Sand Casting Tooling—Core Making for more information.
