Manual Tool Cleaning Operation

Manual tool cleaning is a labor-dependent task (see Labor-dependent and Labor-independent Tasks).

Cycle Time = Tool Cleaning Time / Number of Operators

Cycle time depends on the following:

  • Manual tool cleaning time: this is the time it takes one operator to clean the tool. See formula.

  • Number of operators (specified by the machine property Number of Operators)

Tool Cleaning Time = Tool Surface Area /
Manual Tool Clean Rate

This is the time it takes one operator to clean the tool. It depends on the following:

  • Tool surface area: this is estimated based on the part dimensions and a perimeter allowance. See formula.

  • Manual tool clean rate: this the cleaning rate for one operator in area per unit time. It is looked up by tool surface area in the lookup table tblManualToolCleanRates.

Additional Direct Costs =
Manual Cleaning Agent Cost Per Area * Tool Surface Area

This is the cost for the cleaning agent consumed in one cleaning of the tool. It is the product of the following:

  • Material cleaning agent cost per area (see formula)

  • Tool surface area: this is estimated based on the part dimensions and a perimeter allowance. See Tool Length, Width, and Area.

Manual Cleaning Agent Cost Per Area =
Manual Cleaning Agent Cost Per Volume /
Manual Cleaning Agent Coverage Rate Per Volume

Manual cleaning agent cost per area depends on the following:

  • Manual cleaning agent cost per volume: specified by the tool shop variable costPerVolume_manualCleaningAgent.

  • Manual cleaning agent coverage rate per volume: this is the area of mold covered by a given volume of cleaning agent, in area per unit volume. It is specified by the cost model variable manualCleaningAgentCoverageRatePerVolume (10,000,000mm/L in starting point Digital Factories).
