PLAIN MILLING (Malayalam)

Plain milling, also known as slab or surface milling, is a milling operation that uses a rotating milling cutter with an axis parallel to the workpiece. Here the cutter is positioned so that its cutting edges on the periphery grind at the workpiece rather than its tip. The cutter is mounted on an arbor, which is a shaft that holds and drives the cutter. The arbor is supported by an overarm, which is attached to the column of the machine.
The workpiece is clamped on a table, which can move in three directions: vertical, cross, and longitudinal. The table is mounted on a saddle, which slides along the guideways of the knee. The knee is a rigid casting that supports the saddle and table, and can be moved up or down by an elevating screw. The knee, saddle, and table are collectively called the feed mechanism, which controls the relative motion between the cutter and the workpiece.
The purpose of plain milling is to produce a flat and horizontal surface on the workpiece. The surface finish and accuracy depend on several factors, such as the type and size of the cutter, the speed and feed rate of the machine, the depth of cut, and the material properties of the workpiece.
There are two types of plain milling cutters: plain or cylindrical cutters, and side or face cutters. Plain or cylindrical cutters have teeth on their circumference only, and are used for narrow or shallow cuts. Side or face cutters have teeth on both their circumference and face, and are used for wide or deep cuts.
Plain milling can be performed in two ways: up milling and down milling. Up milling, also known as conventional milling, is when the cutter rotates against the direction of feed of the workpiece. This causes more friction and heat generation, resulting in lower surface quality and tool life. Down milling, also known as climb milling, is when the cutter rotates in the same direction as the feed of the workpiece. This causes less friction and heat generation, resulting in higher surface quality and tool life.
However, down milling requires more rigid and accurate machines, as it tends to pull the workpiece into the cutter. Therefore, up milling is preferred for less rigid machines or when there is backlash in the feed mechanism.
Plain milling is one of the most common and versatile milling operations. It can be used to produce flat surfaces on various parts, such as plates, brackets, covers, frames, etc. It can also be combined with other milling operations to create more complex shapes.
