Valve Machining Cost at 110% machining operations scope included: a worked example

Push machining operations scope included up to 110% and the picture changes. This example computes every intermediate figure at that operating point. Use this when quoting a valve body machining job, comparing in-house vs. outsource cost, or building a BOM cost roll-up for gate, globe, ball, or butterfly valve bodies.

The inputs for this scenario

  • Valve bodies in production run: 50 bodies (unchanged)
  • Loaded machining cost per body: 125 $ / body (unchanged)
  • Machining operations scope included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed setup and tooling charge: 1,800 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable machining cost = valve bodies x loaded cost per body x operations scope) to the inputs above produces each figure below.
  • At this operating point the engine returns 8,675 $ for total valve machining cost, the number this scenario is built around.
  • At this operating point the engine returns 174 $ / piece for machining cost per valve body.
  • At this operating point the engine returns 6,875 $ for variable machining cost (all bodies).
  • At this operating point the engine returns 1,800 $ for fixed setup and tooling charge.

How this compares with the baseline

  • Against the tool's baseline example, where machining operations scope included sits at 100% and the headline result is 8,050 $, this scenario comes in 7.76% above the baseline at 8,675 $.
  • It computes total machining cost as bodies times loaded per-body cost times the operations-scope percentage, plus a fixed setup and tooling charge, and also reports the all-in cost per body. 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

  • Total valve machining cost: 8,675 $ (headline result)
  • Machining cost per valve body: 174 $ / piece
  • Variable machining cost (all bodies): 6,875 $
  • Fixed setup and tooling charge: 1,800 $
