Commercial Kitchen Equipment worked example

Weld Polishing Labor at 18% finish setup, inspection, and rework allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop finish setup, inspection, and rework allowance to 18%, then walk the calculation through step by step. Estimate labor hours required to grind, blend, and polish welds on stainless commercial kitchen equipment.

The inputs for this scenario

  • stainless weld length to polish: 420 linear ft (held at the documented default)
  • weld polishing throughput: 75 linear ft / hr (held at the documented default)
  • finish setup, inspection, and rework allowance: 18 % (the input this scenario stresses; the baseline uses 25)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base weld polishing labor = stainless weld length to polish รท weld polishing throughput.
  • estimated weld polishing labor works out to 6.61 hr at these inputs, and this is the headline figure for the scenario.
  • base weld polishing labor works out to 5.6 hr at these inputs.
  • finish setup, inspection, and rework allowance works out to 18 % at these inputs.
  • weld polishing throughput works out to 75 linear ft / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where finish setup, inspection, and rework allowance sits at 25% and the headline result is 7 hr, this scenario comes in 5.6% below the baseline at 6.61 hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to finish setup, inspection, and rework allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a uniform finish standard and weld condition; a jump from a #4 brush finish to a sanitary mirror polish, or porous welds needing heavy re-grinding, can easily push throughput and rework beyond the entered figures.

Results at a glance

  • estimated weld polishing labor: 6.61 hr (headline result)
  • base weld polishing labor: 5.6 hr
  • finish setup, inspection, and rework allowance: 18 %
  • weld polishing throughput: 75 linear ft / hr
