Worked Example
Verified calculation
Given:
- Cutting Width = 20
- Depth of Cut = 2.5
- Table Feed Rate = 300
Expected Result:
- Metal Removal Rate = 15000
Engineering Interpretation:
Under the given input conditions, the calculated result is: Metal Removal Rate = 15000 mm³/min.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
