railway RRB JE (CBT I + CBT II) Mock Test 2024 Production Engineering (Manufacturing) Machining Processes and Machine Tools Metal Cutting Processes
Which one of the following is the chip thickness ratio?
(where, tc = chip thickness after the cut, to = chip thickness before the cut, f = feed, d = depth and w = width of cut)
1
\(r = \frac{{{t_c}}}{{{t_o}}}\)
2
\(r = \frac{{{t_o}}}{{{t_c}}}\)
3
\(r=\frac{f}{d}\)
4
\(r = \frac{{{t_o}}}{w}\)
