Question

What is the load condition when a relative alignment of machine parts and accuracy of control devices measured?

(a) No load condition

(b) Half load condition

(c) Full load condition

(d) One-fourth load condition

I had been asked this question in my homework.

The doubt is from Alignment Tests on Milling Machine topic in section Machine Tool Metrology of Engineering Metrology

Answer 1

Correct option is (a) No load condition

To explain I would say: The relative alignment of all machine parts and the accuracy of the driving mechanisms and control devices are measured under the condition of no load. The result of these measurements must lie within the prescribed limits.
