Specific cutting energy increases with increasing the cutting speed. a) True b) False

b) false

Explanation:

Specific cutting energy:

Energy required to remove unit volume of material is called specific energy. In other words we can say that the ratio of energy to the volume removal rate is called specific cutting energy.

When cutting speed is increases then specific energy goes to decrease. As well as when depth of cut and feed of tool is increase then specific cutting energy will decrease.
