Hydraulic, Pneumatic & Fluid Power Systems worked example

Manifold Machining Time at 7.2% setup and tool-change allowance: a worked example

This worked example runs the manifold machining time numbers for a tougher week than the baseline: 7.2% setup and tool-change allowance instead of the typical 10%. Calculate manifold machining time for hydraulic, pneumatic & fluid power systems planning, quoting, troubleshooting, capacity review, or process improvement.

The inputs for this scenario

  • Total drilled and tapped features per manifold: 120 units (held at the documented default)
  • Machining throughput rate: 12 units / hr (held at the documented default)
  • Setup and tool-change 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 manifold machining 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 tool-change 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 scheduling a manifold block on a mill or quoting machining lead time for a fluid-power order. 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
