In an orthogonal cutting, the depth of cut is halved and the feed rate is double. If the chip thickness ratio is unaffected with the changed cutting conditions, the actual chip thickness will be
doubled
halved
quadrupled
unchanged

I can't understand how it will be doubled?

Will anybody help me out, please?

It will be halved, not doubled. Because it is not a orthogonal turning case.

I am not getting this. Please explain in detail.

Chip thickness ratio=depth of cut/chip thickness
So, as given depth of cut=1/2,
So = 1/2/chip thickness,
= 1/2*1/cipthickness,
= 2*chipthickness.

So, double chip thickness.

@Srilakshmi

The depth of cut/chip thickness =(depth of cut/2)/(chip thickness/2).
So, chip thickness halves.

What is exact formula of Chip thickness ratio?

Harshal said:   7 years ago
I agree @Ashnad.

Vinayak Karma S said:   7 years ago
Wrong answer. Its halved.
r=T1/T2.
T1'=T1/2,
r=T1/T2=(T1/2)/T2'
-> 1/T2=1/(2*T2'),
->T2=2*T2',
->T2'=T2/2,
-> actual chip thickness will be halved w.r.t first.

In orthogonal cutting feed rate=uncut chip thickness answer is right.

Ravik said:   7 years ago
Correct @Mytey.
