Cutting Parameters
16
Cutting Speed(v)
This is the speed at which work-piece travels
against the tools Cutting edge. Formula to
find out this is V?DN Where V Cutting
Speed in mm/min. D - Diameter of the
work-piece in mm. N - Rotation of the spindle
in rpm. rpm Rotations per minute.
17
Feed(f)
Feed is the distance traveled by the tool cutting
edge into the work-piece during one rotation of
the work-piece in the longitudinal direction(
Parallel to the lathe axis). It is in
mm/revolution
18
Depth of Cut(d)

• Depth of Cut is the amount of penetration of the
  tool tip
• into the Work-piece in the transverse(
  Perpendicular to
• the lathe axis) direction.
• It is in mm
• d can be more for rough turning,( 2 to 4mm)
• d should be very less for the finish turning
• ( .25 to 1mm)

SHAPER
Shaper is a Machine Tool which is power operated
and removes the metal in the form of chip with
the Cutting tool attached to a reciprocating
ram. Basic Motions are Work piece
Stationary Cutting Tool Reciprocating.

Use of Quick Return Mechanism
Quick Return Mechanism in shaper reduces the
un- Productive time by speeding up the return
stroke. Forward Stroke Cutting takes place
Return Stroke - Un-productive
