Mounting Hole Time at 7.2% setup and reposition allowance: a worked example

This worked example runs the mounting hole time numbers for a tougher week than the baseline: 7.2% setup and reposition allowance instead of the typical 10%. Mounting Hole Time estimates how long it takes to drill or punch the mounting holes that fasten a sign, panel or architectural graphic to its substrate or wall.

The inputs for this scenario

  • Mounting holes to drill: 120 units (held at the documented default)
  • Drilling rate per hour: 12 units / hr (held at the documented default)
  • Setup and reposition allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base mounting hole time time = required work รท processing rate.
  • Adjusted run time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base run time works out to 10 hr at these inputs.
  • Allowance applied works out to 7.2 % at these inputs.
  • Process rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where setup and reposition allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • Use it when quoting or scheduling the drilling/punching step for signs, ACM panels, dimensional letters or standoff-mounted graphics before install. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Adjusted run time: 10.72 hr (headline result)
  • Base run time: 10 hr
  • Allowance applied: 7.2 %
  • Process rate: 12 pieces / min
