Doors, Hardware & Access Control Manufacturing worked example

Hinge Prep Cycle Time at 12% template setup and inspection allowance: a worked example

This scenario runs the hinge prep cycle time calculation on the strong side: 12% template setup and inspection allowance, with every other input held at its documented default. Use it when hinge prep cycle time in doors, hardware and access control manufacturing is being added to next week's schedule and you need an honest hours estimate.

The inputs for this scenario

  • Hinge preps to machine: 120 preps (unchanged)
  • Hinge prep machining pace: 12 preps / hr (unchanged)
  • Template setup and inspection allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base hinge prep hours = hinge preps to machine รท hinge prep machining pace) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required hinge prep labor hours, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base hinge prep hours.
  • At this operating point the engine returns 12 % for template setup and inspection allowance.
  • At this operating point the engine returns 12 preps / hr for hinge prep machining pace.

How this compares with the baseline

  • Against the tool's baseline example, where template setup and inspection allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Use it when scheduling a hinge-prep cell or quoting prep labor on a door order with a known count of hinge cutouts. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Required hinge prep labor hours: 11.2 hr (headline result)
