Question

technician a says that the increments on the cut depth dials for the standard cutting head, are in increments of 0.0025\. technician b says you can take up to 0.200\ off each side while still maintaining the optimum surface ra. who is correct?
technician a
technician b
both technician a and technician b
neither technician a nor technician b

Explanation:

Step1: Analyze Technician A's statement

In many standard cutting - head systems, the increments on cut depth dials are often in increments of 0.0025". This is a common and valid specification.

Step2: Analyze Technician B's statement

It is also common in machining operations that a certain maximum amount (such as 0.200") can be taken off each side while maintaining an optimum surface roughness (Ra). This is a practical consideration in manufacturing to ensure surface quality.

Answer:

C. Both Technician A and Technician B
