Robotic End-of-Arm Tooling worked example
Design Review Hours at 12% setup, handling, and delay allowance: a worked example
What does the result look like when setup, handling, and delay allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when design review hours in robotic end-of-arm tooling is changing rate or allowance and you want to see the impact.
The inputs for this scenario
- Design review items to assess: 120 units (unchanged)
- Design review throughput rate: 12 units / min (unchanged)
- Setup, handling, and delay allowance: 12 % (raised for this scenario; the documented default is 10)
Working through the calculation
- Applying the documented formula (Base design review hours time = design review hours workload ÷ design review hours completion rate) to the inputs above produces each figure below.
- At this operating point the engine returns 11.2 hr for required design review hours time, the number this scenario is built around.
- At this operating point the engine returns 10 hr for base design review hours time.
- At this operating point the engine returns 12 % for design review hours allowance applied.
- At this operating point the engine returns 12 pieces / min for design review hours completion rate.
How this compares with the baseline
- Against the tool's baseline example, where setup, handling, and delay 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, and delay allowance is genuinely sustained, not just peaked for a shift. It treats review throughput as constant, so a package with a few unusually complex items — a novel multi-sensor tool changer — will take longer than the average rate predicts.
