Questions and Answers

Which of the following is true about chip formation in machining?

  • Chips are formed as a cutting tool is pulled out of the work material.
  • Chips are formed as a cutting tool is pushed into the work material. (correct)
  • Chips are formed due to the friction between the cutting tool and the work material.
  • Chips are formed due to the heat generated during machining.
  • In which direction does shear occur during chip formation?

  • Shear does not occur during chip formation.
  • In a random direction.
  • In the opposite direction of the cutting tool motion.
  • In the same direction as the cutting tool motion. (correct)
  • What is the extent of plastic deformation during chip formation?

  • Plastic deformation is minimal.
  • No plastic deformation occurs.
  • Plastic deformation is significant. (correct)
  • Plastic deformation is not related to chip formation.
