TOOL LIFE PROBLEMS
, PROBLEM-1
If in turning of a steel rod by a given cutting tool
(material and geometry) at a given machining
condition (so and t) under a given environment
(cutting fluid application), the tool life decreases from
80 min to 20 min. due to increase in cutting velocity,
VC from 60 m/min to 120 m/min., then at what cutting
velocity the life of that tool under the same condition
and environment will be 40 min.?
