Then drop feed by 10 to 15% and you should be fine. I have used 1/8" up and down shear at 18000 - 20000 and usually run 1/8 to 1/4" deep passes multiple times. 150 to 180 IPM works for me, depending on depth of cut and flute length, a long flute out of the chuck makes the bit more delicate, shorter is stronger.
rpm = fpm*12 / pi*D so for a HSS cutter of 0.5", a 750 fpm, that gives an rpm of ~ 5900 ! (this seems too fast) Feed = ftr * T * rpm using ftr of 0.016, 4 flute end mill gives a feed rate of 367 inch/minute are these correct? what values are "reasonable"? (these formulas are from John Walker's Maching Fundamentals)
So for example with a 1/4" HSS endmill in steel, your RPM should be: RPM = 4 x 100/.25 = 1600 Your feedrate should be: ... I use Sumitomo face mills. I have a 1 inch with 2 APKT inserts. Gwizard says 950 SFM, 3700 RPM and 51 in/min in Aluminum. That is WAY too slow.
The chip load per tooth should be equal to the step over already calculated. Milling with a two flute ball mill at 30,000 RPM and a 12 ten-thouhs of an inch chip load per tooth, our feed rate should be 72 inches per minute. Stay Within the Limitations of the Cutter. It's important to stay within your cutter's limitations for optimum ...
Ball Mills Steel Ball Mills & Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis.
Clamping Stability: Try to estimate the overall combined stability of your tool and workpiece.If you are unsure, leave it as "average". Excellent: The workpiece is firmly clamped and supported and the tool is firmly clamped with a short overhang. Poor: The workpiece L/D factor is large (Long shafts) without a steady rest (Luneta) and/or tailstock …

Just so I am clear on the recommendations, when you say 10% of the diameter of a regular end mill or of the diameter of a roughing end mill do you mean that if I am using the full diameter of the end mill, say a 1" diameter, my length/depth of cut should be 0.100" for regular an 1.000" for roughing?
