Updated on: September 25th, 2023
A single-point thread-cutting tool should ideally have______.
- Positive rake
- Negative rake
- Normal rake
- Zero rake
Answer: d. Zero rake
A single-point thread cutting tool should ideally have zero rake angle.
Solution:
A single point thread cutting tool should ideally have zero rake angle. The angle of inclination of the rake surface from the reference plane is known as the rake angle. It’s a crucial factor in a variety of cutting and machining processes. Positive, negative, and zero rake angles are the three types of rake angles.
Positive rake angle: It is utilized when a lower cutting force is required and for low-strength materials such as mild steel.
Negative rake angle: It is used on hard metals that demand a lot of cutting force and are machined at a rapid rate.
Zero rake angle: It is utilized in gear cutting and thread production. Zero rake is used to mill brass and cast iron.
Threading is done by a form tool. The rake angle of the forms tool should ideally be zero.
