Question

8. what precautions would you take in machining with brittle tool materials, especially ceramics? what rake angle (positive or negative) would you choose?

Answer 1

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.
