A thread die will be easier to start if the end of the shaft to be threaded is slightly _______________.
AI Explanation
The correct answer is D) chamfered.
Chamfering the end of the shaft to be threaded makes it easier to start the thread die. Chamfering involves creating a small, angled edge or bevel on the end of the shaft, which helps guide the die onto the threads and facilitates the initial engagement. This is an important technique in threading processes to ensure a smooth and accurate start to the threading operation.
The other options are incorrect because they do not directly address the need to facilitate the initial engagement of the thread die. Center drilling, peening, and reaming do not provide the same benefits as chamfering for starting a thread die.
