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
Q6 | In broaching, generally the broach remains fixed and the workpiece travels providing cutting velocity.
- True
- False
- none
- all
