Set Up Chip Thinning
Enter cutter diameter, target chip load at 50% engagement, and radial depth of cut. The adjustment is intended for side milling with radial engagement below half the cutter diameter.
Radial Chip Thinning Calculator
Calculate a radial chip-thinning feed adjustment when radial engagement is below 50% of cutter diameter.

PRACTICAL CONTEXT
Using the result in real shop work
Light radial engagement reduces maximum chip thickness. This tool uses the circular engagement relationship to estimate the feed-per-tooth required to maintain a target chip thickness.
Where This Result Helps
Use it as a process-development check for light radial cuts, then confirm the final condition with the cutter manufacturer and machine limits.
What Can Distort the Result
Applying the correction above 50% RDOC, confusing programmed feed per tooth with actual maximum chip thickness, or using the calculation without checking tool engagement and manufacturer limits.
ENGINEERING METHOD
How the chip thinning calculation works.
FORMULAEngagement angle α = arccos(1 − 2ae/D). Chip-thinning factor = 1 ÷ sin(α). Adjusted chip load = target chip load × factor.
