Tube, Pipe & Profile Forming worked example
Mandrel Bend Cycle Time at 12% setup & handling allowance: a worked example
What does the result look like when setup & handling allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when mandrel bend cycle time in tube, pipe and profile forming needs a defensible run time before a quote goes out.
The inputs for this scenario
- Bends required in the run: 120 units (unchanged)
- Bender throughput rate: 12 units / hr (unchanged)
- Setup & handling allowance: 12 % (raised for this scenario; the documented default is 10)
Working through the calculation
- Applying the documented formula (Base mandrel bend cycle time time = required work รท processing rate) to the inputs above produces each figure below.
- At this operating point the engine returns 11.2 hr for adjusted run time, the number this scenario is built around.
- At this operating point the engine returns 10 hr for base run time.
- At this operating point the engine returns 12 % for allowance applied.
- At this operating point the engine returns 12 pieces / min for process rate.
How this compares with the baseline
- Against the tool's baseline example, where setup & handling allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
- A figure at this level is achievable when setup & handling allowance is genuinely sustained, not just peaked for a shift. It assumes a single steady throughput rate; complex parts with many different bend angles, plane changes, or tooling swaps mid-run will vary and may need to be split into segments.
Results at a glance
- Adjusted run time: 11.2 hr (headline result)
- Base run time: 10 hr
- Allowance applied: 12 %
- Process rate: 12 pieces / min
