Cutting Speed

Cutting Speed

1 Answer

Answer :

Cutting Speed: - It is the speed at which the metal is removed by the tool from the work piece. In lathe it is the peripheral speed of the work past the cutting tool expressed in meter per minute. Cutting speed is directly proportional to the surface or peripheral sped of the work. It considerably effects on the tool life and efficiency of machining. It affects on machining time there by productivity and the production cost 

Feed: - It is the distance the tool advances for each revolution of the work. Feed is expressed in mm/ rev. It is influenced by the material being machined, geometry of the cutting tool, required degree of surface finish, rigidity of the machine tool being used, and type of coolant being used.
