Q. In ASA system, the side cutting and end cutting edge angles of a sharp turning tool are 45° and 10°, respectively. The feed during cylindrical turning is 0.1 mm/rev. The center line average surface roughness (in µm, round off to one decimal place) of the generated surface is
Ans: 3.75
Sol:
Side cutting edge angle (SCEA) =45o
Ending cutting edge angle (ECEA) =10o
Feed (f)=0.1mm/rev
We have to consider nose radius is zero i.e.,
Ideal surface peak to valley surface roughness.
