Heat Treat Labor Load at 17% labor allowance: a worked example
What does the result look like when labor allowance reaches 17%? The full calculation is worked below with real intermediate numbers. Use it when operators must load, unload, rack, fixture, quench, wash, inspect, document, or move heat treated parts.
The inputs for this scenario
- Loads to process: 18 loads (unchanged)
- Operator load-handling rate: 3 loads / hr (unchanged)
- Labor allowance: 17 % (raised for this scenario; the documented default is 15)
Working through the calculation
- Applying the documented formula (Base heat treat labor hours = heat treat labor workload รท heat treat labor rate) to the inputs above produces each figure below.
- At this operating point the engine returns 7.02 hr for required heat treat labor hours, the number this scenario is built around.
- At this operating point the engine returns 6 hr for base labor hours.
- At this operating point the engine returns 17 % for labor allowance applied.
- At this operating point the engine returns 3 loads / hr for heat treat labor rate.
How this compares with the baseline
- Against the tool's baseline example, where labor allowance sits at 15% and the headline result is 6.9 hr, this scenario comes in 1.74% above the baseline at 7.02 hr.
- A figure at this level is achievable when labor allowance is genuinely sustained, not just peaked for a shift. It models handling labor against a flat per-load rate; it does not capture furnace cycle time, so it tells you the labor needed, not the wall-clock duration of the work.
