Manual Paint Inputs
Manual Paint provides the following options:
Finish Coat Coverage Factor
By default in starting point Digital Factories, finish coats are assumed to be applied to all of the part surface except where there are holes (which are masked by Mask Bench). With the cost model variable defaultFinishCoatCoverageFactor (1 in starting point Digital Factories), Digital Factory Administrators can customize the default, and specify the fraction of the unmasked surface area to paint. With this setup option, users can override the default on a per-part basis.
Note that this fraction also specifies the surface area fraction to sand and clean priori to finish coat application. Primer coat application, as well as sanding and cleaning prior to primer coat application, are always assumed to be performed on the entire unmasked surface area of the part.
Fraction of Part Painted
This specifies the fraction of the total part surface area that requires painting. Note that users may need to manually include the Mask Bench process to account for masking of the non-painted portion of the component (see Fraction Part Masked in the Mask-Bench Inputs section).
By default, this is specified by the cost model variable defaultFractionPartPainted (1 (100%) in starting point Digital Factories). Users can override the default value on a per-part basis with this setup option. The value must be between 0.01 and 1.
Manual Paint Spacing Factor
This specifies the proportion of the paint booth area that can be occupied by parts while providing operators sufficient space to access the parts.
By default, this is specified by the cost model variable defaultManualPaintSpacingFactor (0.5 (50%) in starting point Digital Factories). Users can override the default value on a per-part basis with this setup option. The value must be between 0.01 and 1.
Name of Paint
By default, the paint used is specified by the tool shop variable Default Finish Paint. With this setup option, users can override the default on a per-part basis, and choose from among the finish paints listed in the tool shop Tool Materials table.
The choice of paint drives application time, cure time, and costs for consumable materials (Additional Direct Costs).
Name of Primer
By default, the primer used is specified by the tool shop variable Default Tool Material Name. With this setup option, users can override the default on a per-part basis, and choose from among the primers listed in the tool shop Tool Materials table.
The choice of primer drives application time, cure time, and costs for consumable materials (Additional Direct Costs).
Number of Finish Coats Required
By default in starting point Digital Factories, the cost model assumes that a single finish coat is applied. Digital Factory Administrators can customize the default with the cost model variable defaultNumFinishCoats (1 in starting point Digital Factories). Users can override the default on a per-part basis with this setup option.
Note that each coat is preceded by hand sanding and hand cleaning, and is followed by curing. The number of coats drives cycle time, labor time, and costs for consumable materials (Additional Direct Costs) for all these operations.
Number of Operators
By default, the number of operators is specified by the machine property Number of Operators. With this setup option, users can override the default on a per-part basis. Cycle time is assumed to be inversely proportional to the number of operators.
Number of Parts per Booth
This specifies the number of parts that are painted and cured concurrently. By default, this value is 1 when the cost model variable defaultConcurrentManualPaintCuring is set to false (meaning that parts are painted and cured individually). This is the default value in starting point Digital Factories.
If defaultConcurrentManualPaintCuring is true (meaning that multiple parts are painted and cured concurrently), the maximum number of parts per booth is calculated considering:
-
The length and width of the part
-
The length and depth of the paint booth
-
The value of the setup option Manual Paint Spacing Factor (to ensure that there is sufficient floor space for operators to access the parts)
Users can override the default value on a per-part basis with this setup option. The minimum value allowed is 1.
Number of Primer Coats Required
Note that each coat is preceded by hand sanding and hand cleaning, and is followed by curing. The number of coats drives cycle time, labor time, and costs for consumable materials (Additional Direct Costs) for all these operations.
Rate of Hand Cleaning
By default, the cleaning rate (area per unit time) is specified by the cost model variable defaultHandCleaningRate (30,000mm2/sec in starting point Digital Factories). With this setup option, users can override the default on a per-part basis.
Cleaning rate drives cleaning cycle time and labor time.
Rate of Hand Sanding
By default, the sanding rate (area per unit time) is specified by the cost model variable defaultHandSandingRate (25,000mm2/sec in starting point Digital Factories). With this setup option, users can override the default on a per-part basis.
Sanding rate drives sanding cycle time and labor time.
Rate of Hand Spraying Finish Coat
By default, the finish-coat-spraying rate (area per unit time) is specified by the cost model variable defaultHandSprayRateFinish (5555.5mm2/sec in starting point Digital Factories). With this setup option, users can override the default on a per-part basis.
Finish-coat-spraying rate drives cycle time and labor time for finish coat application.
Rate of Hand Spraying Primer
By default, the primer-spraying rate (area per unit time) is specified by the cost model variable defaultHandSprayRatePrimer (5555.5mm2/sec in starting point Digital Factories). With this setup option, users can override the default on a per-part basis.
Primer-spraying rate drives cycle time and labor time for primer application.
