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.

• Apply tool tack rate: this the application rate for one operator in area per unit time. It is specified by the cost model variable applyToolTackRate (24,000mm2/sec in starting point VPEs).

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 VPEs).
