Saravanan P 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)
