Questions & Answers

Q: What is shear strain in metal cutting?

Shear strain is the ratio of deformation just before fracture to the shortest distance between two shear planes, indicating the extent of deformation in metal cutting.

Q: What are the key properties of tool materials in metal cutting operations?

Tool materials should exhibit properties like hot hardness, wear resistance, toughness, and thermal conductivity to withstand high temperatures and stresses during metal cutting.

Q: How are cutting tools classified in metal cutting operations?

Cutting tools are classified into categories like high carbon steel, high-speed steel, cemented carbides, ceramics, diamond, cubic boron nitride, and more based on their composition and application in metal cutting.

Q: Why are cutting fluids important in metal cutting operations?

Cutting fluids play a crucial role in metal cutting by cooling the tool-chip interface, carrying away heat, protecting surfaces from corrosion, improving finish, and preventing built-up edge formation.
