Fastener Manufacturing & Thread Rolling calculator
Point Forming Time Calculator
Point forming time depends on part geometry, material, point style, feed method, and inspection frequency. This calculator turns quantity and a proven pieces-per-hour rate into adjusted hours for scheduling the secondary operation.
What this calculator does
- Estimate pointing or point-forming hours from fastener quantity, proven pointer rate, and allowance for setup and checks.
- Use it when scheduling drill points, dog points, cone points, gimlet points, chamfers, or other secondary point forming operations.
- Converts point-forming quantity, proven rate, and allowance into scheduled hours for fastener secondary operations.
Formula used
- Base point forming time = fasteners requiring point forming ÷ proven point-forming rate
- Adjusted point forming time = base time × allowance factor
Inputs explained
- Fasteners requiring point forming: undefined
- Proven point-forming rate: undefined
- Pointing allowance for setup and checks: undefined
How to use the result
- Use it to plan drill-point, dog-point, cone-point, chamfer, or other point-forming work after heading and before coating or packaging.
- It assumes the entered rate reflects point geometry, tool condition, feeder performance, and inspection frequency; setup can be added through the allowance or separately.
Common questions
- Which point styles can this estimate? Use it for drill points, dog points, cone points, gimlet points, chamfers, and similar secondary point-forming or pointing operations.
- What rate should I enter? Use a proven rate from a similar diameter, point length, material, tool style, and machine setup rather than a best-case machine speed.
- What belongs in the allowance? Include setup touch time, first-piece approval, tool changes, burr checks, feeder interruptions, and point geometry inspections.
- What decision does the result support? Use adjusted hours to schedule secondary equipment, estimate labor, protect quote lead time, and check whether pointing becomes the bottleneck.
