Which statement accurately compares the efficiency of broaching machines to shaping machines for producing complex internal profiles in workpieces?
1
Broaching machines are less efficient than shaping machines because they require custom-made broaches for each profile.
2
The efficiency of both machines is comparable as they both use a single-point cutting tool for material removal.
3
Shaping machines are more efficient for mass production due to their versatility and adaptability to different profiles.
4
Broaching machines are more efficient than shaping machines for mass production due to their single-stroke operation.
