Manifold Machining Time at 12% setup and tool-change allowance: a worked example

Push setup and tool-change allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when manifold machining time in hydraulic, pneumatic and fluid power systems is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Total drilled and tapped features per manifold: 120 units (unchanged)
  • Machining throughput rate: 12 units / hr (unchanged)
  • Setup and tool-change allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base manifold machining time time = required work รท processing rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for adjusted run time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base run time.
  • At this operating point the engine returns 12 % for allowance applied.
  • At this operating point the engine returns 12 pieces / min for process rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup and tool-change allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It divides the total feature count by the machining rate to get base time, then multiplies by an allowance factor for setup and tool changes. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Adjusted run time: 11.2 hr (headline result)
