Clamp Plate Drill Hours Calculation

Clamp Plate Drill Hours = ((Number of Top Clamp Plate Holes * Hole Drilling Time(Top Clamp Plate Z)) + (Number of Bottom Clamp Plate Holes * Hole Drilling Time(Bottom Clamp Plate Z))) + (Clamp Plate Drill Setup * 2):

  • Number of Top Clamp Plate Holes: This is calculated as whichever is the greatest of: Clamp Plate Holes Min, or (Mold Base Length / Clamp Plate Hole Spacing Length) + (Mold Base Width / Clamp Plate Hole Spacing Width) - 4)) * 2):

    • Clamp Plate Holes Min: This is the minimum number of holes in the clamp plate and is specified by the cmClampPlateHolesMin cost model variable (4 in starting point Digital Factories).

    • Mold Base Length and Mold Base Width are specified by the Mold Base Size – Length and Mold Base Size – Width setup options, respectively.

    • Clamp Plate Hole Spacing Length: This is the linear spacing of clamp plate mounting holes in lengthwise direction and is specified by the cmClampPlateHoleSpacingLength cost model variable (203.2 in starting point Digital Factories).

    • Clamp Plate Hole Spacing Width: This is the linear spacing of clamp plate mounting holes in widthwise direction and is specified by the cmClampPlateHoleSpacingWidth cost model variable (152.4 in starting point Digital Factories).

  • Hole Drilling Time(Top Clamp Plate Z): This is calculated as: (Top Clamp Plate Z / Standard Hole Drilling Rate):

    • Top Clamp Plate Z: This is specified by the cmTopClampPlateThickness cost model variable (75 mm in starting point Digital Factories).

    • Standard Hole Drilling Rate: aPriori performs a lookup in the cmToolMachiningRates table and returns the Rate corresponding to Standard Hole Drilling.

  • Number of Bottom Clamp Plate Holes: This is calculated in the same way as for ‘Number of Top Clamp Plate Holes,’ described above.

  • Hole Drilling Time(Bottom Clamp Plate Z): This is calculated as: (Bottom Clamp Plate Z / Standard Hole Drilling Rate):

    • Bottom Clamp Plate Z: This is specified by the cmBottomClampThickness cost model variable (75 mm in starting point Digital Factories).

    • Standard Hole Drilling Rate: As described above.

  • Clamp Plate Drill Setup: aPriori performs a lookup in the cmToolMachiningSetups table and returns the value of (Number of Setups * Setup Time) corresponding to Clamp Plate Drilling.
