Question

CM GIVES THE VALUE *

Answer 1

Answer:

The higher the value of Cm, the better the machine. Example: if Cm = 2.5, the spread fits 2½ times into the tolerance width, while Cm = 1 means that the spread is equal to the tolerance width.

Answer 2

The Cm index describes machine capability; it is the number of times the spread of the machine fits into the tolerance width. The higher the value of Cm, the better the machine.
