To answer the question regarding "Feed in tapping," let's analyze the relationship between the feed rate and the types of thread pitch.

Key Concepts

1. Thread Pitch: This is the distance between threads on a screw, typically measured in millimeters for metric screws or threads per inch for imperial screws.
2. Tapping: This refers to the process of cutting a thread inside a hole to allow a screw to be inserted.

Answer Explanation

In tapping, the feed rate is typically related to the thread pitch. The common rule is that feed in tapping is equal to the pitch of the thread being used. However, when considering different types of threads, it becomes essential to identify how feed relates to them:

1. Triple Thread Pitch: This does not match the regular pitch for standard tapping.
2. Double Thread Pitch: Similar to triple, it does not provide the correct matching of feed.
3. Quarter Thread Pitch: This also does not align.
4. Half Thread Pitch: Instead, this would imply a longer feed but is also incorrect.
5. Thread Pitch: This is typically the direct relationship we would assume for a standard tapping operation.

Final Answer

The correct option is Thread Pitch.
