Applying Tool Tack Operation
Applying tool tack is a labor-dependent task (see Labor-dependent and Labor-independent Tasks).
Cycle Time = Apply Tool Tack Time / Number of Operators
Cycle time depends on the following:
Apply tool tack time: this is the time it takes one operator to apply tool tack to the tool. See formula.
Number of operators: by default this is specified by the machine property Number of Operators. Users can override the default with the setup option Number of Operators.
Apply Tool Tack Time =
Tool Surface Area / Apply Tool Tack Rate
This is the time it takes one operator to apply tool tack to the tool. It depends on the following:
Tool surface area: this is estimated based on the part dimensions and a perimeter allowance. See Tool Length, Width, and Area.
Additional Direct Costs = Tool Tack Cost Per Area *
Tool Surface Area
This is the cost for the tool tack material consumed in one coating of the tool. It is the product of the following:
Tool tack cost per area (see formula)
Tool surface area: this is estimated based on the part dimensions and a perimeter allowance. See formula.
Tool Tack Cost Per Area =
Tool Tack Cost Per Volume /
Tool Tack Coverage Rate Per Volume
Tool tack cost per area depends on the following:
Tool tack cost per volume: this is the value of the tool shop variable Cost Per Volume Tool Tack.
Tool tack coverage rate per volume: this is the area of mold covered by a given volume of tool tack, in area per unit volume. It is specified by the cost model variable toolTackCoverageRatePerVolume (17,500mm2/liter in starting point Digital Factories).
Curing Tool Tack Operation
Curing is a labor-independent activity, assumed to carry no labor cost. The curing time is specified by the cost model variable toolTackCureTime (35 seconds in starting point Digital Factories).
