Face milling can be achieved with an end mill, but is often done with a face mill, shell mill or a fly cutter. Face milling can be done in both manual machining and CNC machining. To obtain a smoother surface finish it is best to let the machine feed the table. Newer manual milling machines and CNC machines will have this option, but older ...
Mill: Translates programs consisting of specific numbers and letters to move the spindle (or workpiece) to various locations and depths. Can either be a Vertical Milling Center (VMC) or a Horizontal Milling Center, depending on the orientation of the spindle. Many use G-code. Functions include: face milling, shoulder milling, tapping, drilling ...
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
Contouring/Profiling: this is a process used to mill different surfaces such as flat or irregular ones. This type of process can be done during the roughing or finishing phase of the overall operation. [3] Facing: is an operation used to face the part down to specified dimension. Facing can be done using end mills or a special face mill. [4] [5 ...
In face milling, the cutting action occurs primarily at the end corners of the milling cutter. Face milling is used to cut flat surfaces (faces) into the work piece, or to cut flat-bottomed cavities. In peripheral milling, the cutting action occurs primarily along the circumference of the cutter, so that the cross section of the milled surface ...
Milling operations are operations where the cutting tool with cutting edges along its cylindrical face are brought against a workpiece to remove material in the profile of the spinning tools shaft and lower edge. [7] Milling machines are the principal machine tool used in milling. Advanced CNC machines may combine lathe and milling operations.

Inserts used for turning and milling are often numbered according to ISO standard 1832. This standard aims to make the naming, specifying and ordering of inserts a simple, consistent and traceable process. This standard takes into account both metric and imperial systems of units, although certain elements differ for each unit system.
