Answer: Negative!
Step-by-step explanation:
With brittle tool materials, we first want to prevent chipping, such as by using negative rake angles and reduce vibration and chatter. Also, brittleness of ceramic tools applies to thermal angles and reduce vibration and chatter. Also,
brittleness of ceramic tools applies to thermal
gradients, as well as to strains. To prevent tool
failures due to thermal gradients, a steady supply of cutting fluid should be applied, as well
as selecting tougher tool materials.
