How fast should the blade be spinning when it contacts material being cut?
- A.
Blade must be revolving at full speed before it contacts material being cut.
- B.
Gradually place blade up against material and build up speed towards the end of the cut.
- C.
Maintain a slow and positive cut flow from end to end.
- D.
Blade should be place right against material then brought up to full speed throughout the cut.
Correct Answer
A. Blade must be revolving at full speed before it contacts material being cut.Explanation
The correct answer is "Blade must be revolving at full speed before it contacts material being cut." This is because starting the blade at full speed ensures that it can effectively cut through the material without getting stuck or causing any damage. Gradually placing the blade against the material or maintaining a slow cut flow may result in an inefficient or ineffective cut. Bringing the blade up to full speed throughout the cut may also cause the blade to catch or bind on the material. Therefore, it is important to have the blade spinning at full speed before it comes into contact with the material being cut.Rate this question:
