Turning is the machining operation that produces cylindrical parts. In its basic form, it can be defined as the machining of an external surface:
with the workpiece rotating,
with a single-point cutting tool, and
with the cutting tool feeding parallel to the axis of the workpiece and at a distance that will remove the outer surface of the work.
Taper turning is practically the same, except that the cutter path is at an angle to the work axis. Similarly, in contour turning, the distance of the cutter from the work axis is varied to produce the desired shape.
Even though a single-point tool is specified, this does not exclude multiple-tool setups, which are often employed in turning. In such setups, each tool operates independently as a single-point cutter.Metal copper electroplate part OEM&ODM
