On This Page

This set of Manufacturing Processes Multiple Choice Questions & Answers (MCQs) focuses on Sawing and Broaching Machines

Q1 | What is the main advantage of broaching over shaping process?
  • Use of single point cutting tool which are inexpensive and can be grounded to any shape
  • Thin or fragile jobs can be conveniently machined because of lower cutting forces
  • Surfaces with obstruction can also be machined
  • Removal of the whole material in one stroke
Q2 | For which of the following operations, broaching can be used?
  • Threading
  • Grinding
  • Spline cutting
  • Increasing the size of the existing hole for a certain length
Q3 | Why push type broaches are made shorter in length?
  • To reduce machining time
  • To increase the efficiency
  • For easy handling of the tool
  • To avoid buckling
Q4 | Why chip breakers are provided on the broach?
  • To reduce machining time.
  • To increase the cutting force by breaking the chips
  • To reduce the friction between tool surface and the workpiece by breaking the chips
  • To break up the wide curling chips
Q5 | Why neck section provided in the pull type broaches are made shorter in diameter?
  • To provide better surface finish
  • To remove chips easily
  • To allow failure in case of overloading
  • For holding purpose
