Problem 7:

Consider a slab milling operation.  Milling machine holds the tool horizontally.

The length and the width of the part are 850 mm and 30 mm respectively.

Tool diameter is 40 mm The number of the installed inserts was 10.

Feed per tooth is 0.3 mm/tooth. Cutting speed is 1 m/sec.

Depth of cut is 2 mm.  Specific energy is 2 W.s/mm3

a)  Find the machining time?

 

b)  Calculate the MRR

 

c) What would be the required power?

 

d) Find the necessary torque?
