To cut double-start screw threads of pitch 1.0 mm on a lathe, the thread cutting tool should have a feed rate of 2.0 mm/rev.
Thread cutting is the process of creating screw threads on a workpiece using a lathe. The feed rate of the cutting tool determines how fast the tool moves along the workpiece, which in turn determines the pitch of the threads.
Here's an explanation of why the correct answer is option 'C' (2.0 mm/rev):
1. Understanding the pitch of the screw threads:
- The pitch is the distance between adjacent threads on a screw.
- In this case, the pitch is given as 1.0 mm, which means that there is a 1.0 mm distance between the centerline of two adjacent threads.
2. Understanding double-start screw threads:
- Double-start threads have two threads winding around the screw axis instead of one.
- This means that for every revolution of the screw, the thread advances by two times the pitch.
- In other words, the distance traveled by the thread in one revolution is twice the pitch.
3. Determining the feed rate for double-start screw threads:
- The feed rate of the cutting tool is the distance the tool moves along the workpiece for one revolution of the workpiece.
- Since double-start threads have a thread advancement of two times the pitch for each revolution, the feed rate should also be two times the pitch.
- In this case, the given pitch is 1.0 mm, so the feed rate should be 2.0 mm/rev.
Therefore, the correct answer is option 'C' (2.0 mm/rev) because the feed rate of the thread cutting tool should be two times the pitch for cutting double-start screw threads.

Therefore, the correct answer is option 'C' (2.0 mm/rev) because the feed rate of the thread cutting tool should be two times the pitch for cutting double-start screw threads.
