Care should be exercised when grinding and measuring the following on the Acme threading tool. Which is correct? A. Back rake, thread angle, and relief angles B. End flat width, relief angle, and thread angle C. Side rake angle, thread angle, and relief angles D. Side rake, back rake, and relief angles

Respuesta :

Answer:

B). End flat width, relief angle and thread angle

Explanation:

Special care should be taken when grinding and measuring the Acme threading tool because after machining the Acme threading tool, the end flat width, relief angle and the thread angle can change the dimensions of the work piece. So precision measures should be observed while machining as altering these parameters can result in the product with a dimension other than the required dimensions.
