GATE 2021
Easy
The correct sequence of machining operations to be performed to finish a large diameter through hole is
- drilling, boring, reaming
- Bboring, drilling, reaming
- Cdrilling, reaming, boring
- Dboring, reaming, drilling
Explanation
Drilling creates the initial rough hole; boring enlarges and corrects concentricity/straightness for a large-diameter hole; reaming provides the final precision finish.
