WHAT IS CUTTING SPEED ?

HOW IT WORK

                               TODAY I WILL GIVE U INFORMATION ON HOW TO USE CUTTUNG SPEED WHICH IS GIVEN BY INSERT MANUFACTURER ON THE BACK SIDE OF INSERT BOX IF U WORKING ON CNC MACHINE THEN YOU KNOW WHAT I AM TALKING ABOUT

SO LETS GET START

Speed of the tool with respect to job when the job (work piece) is cut is called the cutting speed.

FOR MILLING MACHINE -

milling machining

suppose we machining work piece with a tool 120mm in diameter at a cutting speed of 80 m/min

The spindle speed is approximately 212 min-1, we can calculate from N=1000*v/3.14*D

 

N=spindle speed

D=diameter of cutter

V=cutting speed

        N=1000*80/(3.14*120) = 212.3

now you understand how to use cutting speed in milling machine

FOR LATHE CUTTING:

LATHE MACHINING

when a job 200mm in diameter should be machined at a cutting speed of 300m/min

the spindle speed is approx. 478min-1  which is obtained from N=1000*v/3.14*D

               N=1000*300/(3.14*200)= 477.07

NOTE:-

                   when the workpiece diameter is changed, the cnc changes the spindle speed 

so that the cutting speed remains constant
