Question

Which of the following is a reason for pitch errors observed in threads?

• A. Lack of inspection
• B. Incorrect ratio of tool work velocity
• C. Interference between mating parts
• D. Less skilled operator

Hint:

To minimize pitch errors in threaded components, ensure that the correct tool-work velocity ratio is maintained during the manufacturing process.

Answer 1

The Correct Option is B

Pitch errors in threads typically arise due to an incorrect ratio of tool work velocity during the manufacturing process. This can result in inaccuracies in the spacing between the threads, leading to pitch variations. While factors like lack of inspection, interference between mating parts, and operator skill can influence thread quality, the most common cause of pitch errors is the improper setting of cutting speeds and tool-workpiece engagement.
