Manufacturing and automation as a recovery path toward sustainable growth

It is a process performed with a rotating cutter to subtract the material from a rectangular/square bar. Unlike the lathe machine, where the workpiece is rotated against the tool, a milling cutter spins against the workpiece. Important steps to be followed to avoid any mistake during milling operation are detailed in Annexure-IV.
Aluminum-Manufacturing Methods

A turning operation is an operation where the workpiece or the tool is rotated to remove material to manufacture a finished component (usually performed with a lathe or mill). Mills and lathes are very suitable for aluminum alloys. Milling uses a rotating tool that continuously brings fresh edges into action. Lathes use a stationary tool that cuts a rotating workpiece where the same cutting edge is continuously in use. For both mills and lathes, the feeds and speeds are incredibly important.
Turning Operations and Machines
Published in Zainul Huda, Machining Processes and Machines, 2020
The lathe is one of the basic machine tools for industrial applications since a wide variety of shapes and forms can be created by turning and related operations. In industrial practice, lathes produce a wide range of machined parts; these include drive shafts of cars, gun barrel, crankshaft, screws, locomotive wheels, legs for tables, and many other engineering components. Heavy-duty large-scale lathes can be used to machine a giant metal cone or disc, while small-scale machines can cut out even a chess piece. A lathe revolves the workpiece on its axis for performing a wide range of machining operations; these turning-related operations include straight turning, taper turning, cutting, knurling, boring, reaming, grooving, chamfering, facing, threading, and the like. There are various types of lathe machines to meet the diversified industrial needs (see Section 5.3).

Ostwald and Muñoz (1997) explained that machine tools provide a driving force that creates relative motion between the tool and the workpiece. A wide variety of relative motions exist. For instance, a lathe rotates the workpiece and moves the tool, whereas a milling machine rotates the tool and moves the workpiece. By controlling this relative motion, precise cutting can be achieved to remove the unwanted parts of a metal workpiece.
