Compensation factor
Factor = D / [2 x sqrt(ae x (D - ae))]Applied only when radial width of cut is less than half the cutter diameter.
Machining / interactive calculator
Radial Chip Thinning Calculator
Compensate programmed chip load when radial engagement is below 50% of cutter diameter, and calculate the resulting table feed.
mm
Use the effective diameter at the cutting depth.
mm
Compensation applies below 50% radial engagement.
mm/tooth
Use the toolmaker's chip-load starting point.
z
Number of cutting edges used for table-feed calculation.
RPM
Enter the programmed spindle speed.
Formula & assumptions
How radial chip thinning is calculated
Adjusted table feed
Feed = adjusted fz x flutes x RPMThe result maintains the target maximum chip thickness during constant, light radial engagement.
Production application disclaimerDo not carry the compensated feed into full-width slots, tight internal corners, plunges, or non-constant-engagement toolpaths. Verify toolmaker limits, machine acceleration, runout, rigidity, and workholding.
