turning roughing pass count calculator online

Use turning roughing pass count online for initial diameter mm, final diameter mm, radial cut mm. Ideal machining arithmetic. Supplied cutting data are illustrative, and tool limits, workholding, machine protection and real cycle behavior require independent review.

How to use it

Enter initial diameter mm. Set final diameter mm, radial cut mm. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
initial diameter mmMain input. Positive values. 50
final diameter mmOption. Positive values. 40
radial cut mmOption. Positive values. 2

Calculation method

passes = ceil(positive(initial_diameter_mm-final_diameter_mm)/(2*radial_cut_mm)) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply turning roughing pass count to the case below, keeping the displayed units and assumptions. Ideal machining arithmetic. Supplied cutting data are illustrative, and tool limits, workholding, machine protection and real cycle behavior require independent review.

Choose the right tool

Use cutting data suitable for the actual tool and material. Effective diameter, engagement and chip thickness affect the applicable formulas. Cycle estimates do not generate machine-ready instructions or validate safe operation.

Limitations and common mistakes

  • Ideal machining arithmetic. Supplied cutting data are illustrative, and tool limits, workholding, machine protection and real cycle behavior require independent review.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
