In the application of RSM end mills, it is vital that ad max mm2 is not exceeded, for this, adjust ae & ap accordingly.
Example: When using ae (max), Then ap = ad max mm 2 / ae max When using ap max, then ae = ad max mm2 / ap max = 15.5 / 1 = 15.50 / 32.50 hm = 15.50mm = 0.47mm

Cutting Section (ad) and Speed (Vc) Correction Coefficients
When the length to diameter (Lu:D) exceeds 3:1 the cutting When the length to diameter (Lu:D) exceeds 3:1 the speed section (ad) should be reduced as per the following graph. (Vc) should be reduced as per the following graph. How to correct the cutting section with the ratio: the reach / cutting diameter How to correct the speed with the ratio: the reach / cutting diameter
