Question 43
MENAT2 marksNeeds review
A cylindrical bar with 200 mm diameter is being turned with a tool having geometry 0° - 9° - 7° - 8° - 15° - 30° - 0.05 inch (Coordinate system, ASA) resulting in a cutting force
. If the tool geometry is changed to 0° - 9° - 7° - 8° - 15° - 0° - 0.05 inch (Coordinate system, ASA) and all other parameters remain unchanged, the cutting force changes to
. Specific cutting energy (in J/mm
) is
, where
is the specific energy coefficient, and
is the uncut thickness in mm. The value of percentage change in cutting force
, i.e.
, is ______ (round off to one decimal place).Log in to check the answer
