Fastener Manufacturing & Thread Rolling worked example

Point Forming Time at 11% pointing allowance for setup and checks: a worked example

Suppose pointing allowance for setup and checks falls to 11%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate pointing or point-forming hours from fastener quantity, proven pointer rate, and allowance for setup and checks.

The inputs for this scenario

  • Fasteners requiring point forming: 30,000 pieces (held at the documented default)
  • Proven point-forming rate: 6,000 pieces / hr (held at the documented default)
  • Pointing allowance for setup and checks: 11 % (the input this scenario stresses; the baseline uses 15)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base point forming time = fasteners requiring point forming รท proven point-forming rate.
  • Adjusted point-forming hours works out to 5.55 hr at these inputs, and this is the headline figure for the scenario.
  • Base point-forming hours works out to 5 hr at these inputs.
  • Pointing allowance applied works out to 11 % at these inputs.
  • Point-forming rate works out to 6,000 pieces / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where pointing allowance for setup and checks sits at 15% and the headline result is 5.75 hr, this scenario comes in 3.48% below the baseline at 5.55 hr.
  • It computes the machine hours to point-form a fastener lot, adding a setup and inspection allowance to the base run time. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Adjusted point-forming hours: 5.55 hr (headline result)
  • Base point-forming hours: 5 hr
  • Pointing allowance applied: 11 %
  • Point-forming rate: 6,000 pieces / hr

Run it with your numbers
