 Lathe is a machine that helps in shaping several material

pieces in the desired shapes.


 Shaping up different materials and performing various functions such as
sanding, deformation, cutting, facing, knurling, drilling, turning and much more
is done with the lathe machines
 The general operations done with the lathe
are grooving, turning, cutting, sanding , etc
TYPES OF LATHE OPERATION
1. facing/turning tools:
 Facing is the process of removing metal from the end of a work
piece to produce a flat surface
 This tool should be used if we need to shorten the length of the
stock or make the diameter smaller.
 Its main function is to face the stock so we can have a nice smooth
surface to work with.
 Chamfering is the operation of beveling the extreme end of the work piece.

 Chamfering is an essential operation after thread cutting so that the nut may pass
freely on the threaded work piece.

 This tool should be used if we need to make a chamfer on the edge of a work
piece Or to break an edge.
 Knurling is the process of embossing a diamond shaped
pattern on the surface of the work piece.

 This tool should be used if we need to put a knurling on


our stock. This is normally used on knobs where better
grip is needed.
 Parting or cutoff is the operation of cutting a piece off by slicing a
groove all the way through it with a special parting or cutoff tool

 This tool should be used if we need to cut some of the stock off to
shorten it.
 These tools are generally thin blades of HSS
This tool should be used if we need to cut a
channel into the stock. Such as O-ring
groves or any other small depth groove.
 These can cut outside surfaces and edges.
 There are versions that consist of a piece of
carbide brazed onto a rectangular steel bar.
