PRECAUTIONS IN USE OF MILLING CUTTER 

The milling machine must be stopped before setting up or removing a workpiece, cutter, or other accessory.



All the chips should be removed from the cutter. A wiping cloth should be placed on the cutter to protect the hands



If cutting teeth are dull, these should be sharpened on a tool and cutter grinder. CH/ONTC/PT

PRECAUTIONS IN USE OF MILLING CUTTER 

Burrs should be removed from the milling cutter with an abrasive stone.



Hole type milling cutters should be stored on a rack. It should be ensure that the teeth do not hit other cutter or metal parts.



The cutter should be rotated in right direction only

MACHINING TIME CALCULATION 

FEED : It is the distance that the work advances in the time when the cutter turns through one complete revolution. The feed is expressed in millimeter per revolution.

Sm = N x Srev = (Sz x Z) x N Where, Sm = Feed per minute. Srev = Feed per cutter revolution. Sz = Feed per tooth Z = number of teeth in the cutter. n = the cutter speed in r.p.m CH/ONTC/PT

MACHINING TIME CALCULATION 

CUTTING SPEED : The speed of cutter is its peripheral linear speed resulting from rotation. It is expressed in meters per minute. v

Where,

πdn m/min 1000

V = Cutting speed in m/min. D = Cutter diameter in mm. N = cutter speed in rpm. CH/ONTC/PT
