The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round …
Milling Formulas Speed (RPM) = (SFM x 3.82) / D Feed (IPM) = RPM x FPT x Z SFM (Surface Feet per Minute) = (RPM x D) / 3.82 IPT (Inches per Tooth) = (IPM / RPM) / Z MRR (Cubic Inches per Minute) = IPM * WOC * DOC AFPT (@ less than 1/2 dia. WOC) = IPM x sqroot of (D / WOC) HP (Horsepower Consumption) = MRR x mf mf - steel = 1 mf - gray iron = .65

The endmill can't cut a corner any smaller than it's own radius, but when the endmill and corner radii are the same, it's particular likely to cause problems. Make the endmill slightly smaller. You may have to increase the corner radius if you customer will allow it, or do something sneaky, like use a metric size if it is closer than the ...
3D Profiling with ball end mills on 5 axis. OK on 5 axis machine's we do a lot of 3D profiling. Question is recently we have been trying to shorten 30 hour plus cycle times. One idea I thought of is to tilt the ball mill's so you are not cutting on the tip of the ball (using the cutting flutes instead)which helps not having the tip dragging ...
decreases, feed rate increases to maintain the same chip thickness. Use the formula below to find your ideal cutting condition. Adjusted Feed Rate = IPT x D 2 x O(D x RDOC) – RDOC IPT = IPT @ 50% RDOC D = Cutter Diameter RDOC = Radial Depth of Cut Ball Nose End Mill Ball nose end mills are commonly used for finishing contoured surfaces.

A solid-body ballnose end mill requires a high spindle speed to remove material productively. This is true not just because the tool has a smaller nominal diameter, but also because the light cut on the ball means the actual cutting diameter is smaller still. This spindle speed is the reason why axial chip thinning is often associated with high ...

formula says with chip thinning with ball end mill <10800 rpm <41 ipm feed. so basically your feed was not that bad but still wouldn't hurt to lower rpm and feed as it maybe it's more the milling hard steel problem.
Chip thinning comes into play when you make a cut that's less than half the diameter of the cutter wide. This is very common, especially with high-speed machining toolpaths. For example, with a 1/2″ end mill, you might specify a cut that's 20% of the diameter, or 0.100″ wide.

Calculate the Feed per Tooth, based on the Chip load and Chip thinning factors: F z = C L × R C T F × A C T F. Calculate the RPM from the Cutting Speed and Cutter Diameter: n = V c × 12 π × D. * If your Vc is in m/min units use 1000 instaed of 12 in the above formula. Final Stage: Calculate the Table Feed: V f = F z × n × Z.
At this stage, the material is known, the endmill geometry is known, chip thinning is accounted for, which gave us an adjusted target minimal chipload. The remaining part is to chose a specific combination of RPM and feedrate values that together will produce this chipload, following the formula described earlier.
High Feed End Mills - Steels up to 45 Rc - Variable Pitch - Reduced Neck The specifically engineered end profile of this fully stocked offering of High Feed End Mills reduces cutting forces, while its reduced neck geometry provides maximum strength in long reach and deep pocketing applications.
Axial Chip Thinning occurs when a radius (ball) endmill is used and the stepdown or vertical engagement into the material is less than the radius of the cutter (see Figure 1). When Axial Chip Thinning occurs, the effective diameter of the tool changes: the effective diameter of the tool is much smaller than the actual diameter due to material ...
