b.on what factors does the tool life depend?
c.how the thread are made on lathe
d.what are the different kinds of automatic lathes in the multi-spindale category?
e.what is interrupted cutting

b.explain broaching with the help of figure and example?(5)

patr b
ques. no 3.
elaborate the differences ranging from automatic lathe and capstan lathe ?give an example component suited for capstan lathe with dimension?(15)

Part C
ques. no 4

the subsequent observations were made during an orthogonal cutting operation

Tool rake angle=10 degree ,co-efficient of friction=.85,chip thickness=2.5mm,width of cut=15mm,cutting speed =40m/min,feed=1.5mm/rev,shear strenght=650N/mm2(15)

Determine the subsequent
1.chip thickness ratio
2.shear angle
3.shear force
4.friction angle
5.cutting force
6.power consumed at the cutting tool.


Questoin no 5
