Maximum and Average Chip Thickness in Milling

Q. During a conventional milling operation, if depth of cut gets doubled where as the cutter diameter reduces to half, then what will be the percentage change in maximum uncut chip thickness ?

1. 0 %
2. 50 %
3. 100 %
4. 200 %

Q. Common Data for Q 6.124 and Q.6.125
Data for plain milling operation are given below:
Length of work piece = 200 mm,
Cutter speed = 100 rpm,
Feed = 200 mm/min, Depth of cut = 2 mm,
Tota clearance (entry and exit) = 5 mm

Mean un-deformed chip thickness (in microns)

1. 142
2. 100
3. 71
4. 50
