0.002 is the example result. Read it using the units and relationship stated below.
CNC Axial Chip Thinning uses programmed chip load, cutter engagement (%).
Keeping feed calculations attached to the cutting conditions
For cnc axial chip thinning, the relationship is For radial engagement e = engagement% ÷ 100 below 0.5, adjusted feed per tooth = target maximum chip thickness ÷ sqrt(1 − (1 − 2e)²). At engagement of at least 50%, no radial correction is applied. This assumes ideal peripheral milling geometry. The amount depends on the supplied programmed chip load, cutter engagement (%), rather than a live market price or a value imported from another record. A machining relationship connects diameter, speed, feed and engagement. It does not choose a safe starting point without the cutter, material and setup. Manufacturer cutting data should provide the process assumptions used in the form.
What the model includes
For radial engagement e = engagement% ÷ 100 below 0.5, adjusted feed per tooth = target maximum chip thickness ÷ sqrt(1 − (1 − 2e)²). At engagement of at least 50%, no radial correction is applied. This assumes ideal peripheral milling geometry. Keep millimetres and metres distinct, and record whether feed is per tooth, per revolution or per minute. A correct conversion can still be unsuitable when tool reach, workholding, machine limits or chip evacuation changes. Use the result as a conversion or comparison, then validate the process against the tool guidance and machine capability. This page does not replace a tested setup sheet or account for every cutting condition.
Example with the supplied inputs
Programmed chip load: 0.002; Cutter engagement (%): 40. Result: 0.002. The values are illustrative.
Compare one changed input
Programmed chip load changes from 0.002 to 0.0022. The result becomes 0.0022. All other inputs remain fixed.
Calculation rule
For radial engagement e = engagement% ÷ 100 below 0.5, adjusted feed per tooth = target maximum chip thickness ÷ sqrt(1 − (1 − 2e)²). At engagement of at least 50%, no radial correction is applied. This assumes ideal peripheral milling geometry.
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Programmed chip load | 0.002 | Use the source quantity represented by programmed chip load. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Cutter engagement (%) | 40 | Enter cutter engagement (%) on the percentage scale used in the formula (20 means 20%, not 0.20). Keep its base and reporting period consistent with the other inputs. |
Output: 0.002 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Programmed chip load, Cutter engagement (%). Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Programmed chip load on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 0.002.
Change Programmed chip load from 0.002 to 0.0022 while keeping every other value fixed. The result becomes 0.0022. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
