Cutting Parameters Saravanan P
Cutting Speed(v) This is the speed at which work-piece travels against the tool’s 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. Saravanan P
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” Saravanan P
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) Saravanan P

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 Saravanan P
