Q: Gear lapping: correct stage in the manufacturing sequence At what stage is gear lapping typically carried out to improve surface finish and accuracy? Choose the correct option.

Concept Lapping is a finishing process to correct minor errors and improve finish/quietness. It is commonly done after heat treatment so that final hard geometry is finished to accuracy. Final Answer After heat treatment

Difficulty: Easy

After heat treatment
Prior to heat treatment
Only for gear reconditioning
None of these
