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.
The number of revolutions the milling tool makes per minute on the spindle. This is a machine-oriented value, which is calculated from the recommended cutting speed value for an operation. Feed per tooth, f z. A value for calculating the table feed. The feed per tooth value is calculated from the recommended maximum chip thickness value.
There are also several factors to be considered when choosing the proper RPM and feedrate. The feed rate used depends upon a variety of factors, including power and rigidity of the machine, rigidity of part hold-down, spindle horsepower, depth and width of cut, sharpness of cutting tool, design and type of cutter, and the material being cut.
Feed rate (IPR) IPR - Also called, feedrate, or called simply feed) is the relative velocity at which the cutter is advanced along the workpiece. ... Back in the days of belt driven milling machines and slide rules, the old school machinists had a simple method of calculating RPM.

The approximate values given in table 8-1 in Appendix A may be use as guide for selecting the proper cutting speed. If the operator finds that the machine, the milling cutter or the workpiece cannot be handled suitably at these speeds,immediate readjustments should be made. Table 8-1 lists speeds for high speed steel milling cutters.
If the tool breaks yet again, try reducing the feed rate to put less stress on the tool. Once you've found a combination of speeds and feeds that's successful, you can focus on surface finish. Try slowly increasing the values you reduced, until the milled area appears smooth and the milling machine's vibration and noise is reduced.

A milling machine is basically used for shaping, routing, boring, and drilling metals and other solid materials. Generally there are two categories of the milling machine which include the vertical type and the horizontal type. In order to optimize the capacity of the milling machine, it is essential to identify the appropriate milling machine type for specific tasks.
