You may have heard of the machining process, called turning, in which a cutting tool is used to creates lines and grooves in a piece of metal. The finished pieces are often considered subjects of turning operations. If you are in an industry that uses lathe turning, you should know what these operations are.
Turning
Turning refers to cutting a piece of metal while it is being rotated perpendicular to a cutting tool. It can be applied to both internal and external surfaces. The workpiece is what is being turned.
Facing
Facing involves starting on the edge of a workpiece and pushing the cutting tool forward to remove material from the end. This is generally performed on the lathe like standard turning. It is often the first and last thing to be done to a workpiece.
Parting
Parting means cutting deep grooves into a piece. This is most commonly used to break materials into multiple pieces.
Grooving
Grooving also involves cutting deep grooves into a workpiece, although these are not designed to sever materials. It can be performed on internal and external surfaces.
Drilling
Machine operators use drilling to remove the inside of a workpiece. If using a lathe, this will involve a stationary drill bit and turning workpiece. However, this process is typically done on a separate drilling machine.
Boring
Boring involves enlarging an existing hole made by drilling. This is most commonly done on a lathe. However, some pieces will be too awkward for a machine and need to be done elsewhere. For instance, you may need a long bed lathe and special adaptations to bore certain items. This is often left to skilled machinists.
Turning is the process of remove material from a workpiece that is rotating. If you are in the machining industry, you must understand the different operations you may encounter.
