Mathematical description of ball mill performance as a
having a grate discharge. The ball mill, driven by a 1.5 hp motor, operated at a fixed speed of 53.8 rpm. This speed was 78.5 percent of the critical speed. The normal operating ball load was set at 230 pounds, and was comprised of 2.5, 2.0, 1.5, 1.0, and 0.75 in. diameter cast iron balls. The maximum size ball was determined by the equation

CoroMill® 216 is a robust ball nose end mill for roughing and semi-finishing of curved surfaces. The tools are easy to apply in machining centers, CNC milling machines and copy-milling machines for die and mold, aerospace, automotive and associated industries.
When milling or drilling, or creating a tool path for a CNC machine the feed rate must be determined. Materials have rated surface speeds for a given type of cutter. The harder the material the slower the speed. Given the diameter of the tool and the surface speed, the RPMs of the spindle can be calculated. Then if the tooth load for the cutter is know, and the number of teeth, the feed rate

Many times the industry you work in will dictate how you calculate design safety factors. More often than not fatigue is your biggest problem not yield. Eric Lee (Austal) In my opinion, safety factors are really only important in certain cases. In the industries that I've worked in (shipbuilding/offshore) safety factors are hardly the criteria we work to. We do have our allowable stresses

The Milling ProcessDefinitions 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 insert cutters

Milling Speed and Feed Calculator Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill.
How to use Choose a type of operation (drilling, reaming, boring, counterboring, face milling, slab milling/side milling, end milling, or turning), select your stock material, choose a material for the tool (high-speed steel or carbide), input the quantity of teeth for the tool and the diameter of the workpiece/cutter. Hit the "Calculate
For side milling the same cutting speed as for slot milling can. Axial depth of cut, a p = 1.5 x D be used, but the feeds must be adjusted in order to obtain asuitable average chip thickness. Correction factor for side milling Divide the cutter diameter with the radial depth of cut. See in the chart below which correction factor, Cf, this corresponds to, and multiply the chosen feed

Which Drill Point Angle Should I be Using?Regal Cutting
The selection of an appropriate drill point angle for your bit should be informed by questions about your application. Yes—a hole is a hole is a hole—but what is the purpose of the hole, what type of metal are you cutting into, and what are the specifications for the finished hole? In addition to the drill point angle, factors that can affect successful drilling include

In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.As the speed of rotation approaches the object's natural frequency, the object begins to resonate, which dramatically increases system vibration.
