Question

Find part zeros using an _____________ _______________ and the DRO to locate the sides of the part

A) Optical comparator
B) Edge finder
C) Micrometer
D) Protractor

Answer 1

To find part zeros, you can use an Optical Comparator and the DRO to locate the sides of the part.

Step-by-step explanation:

In order to find part zeros, you would use an Optical Comparator and the DRO (Digital Readout) to locate the sides of the part. The Optical Comparator uses a light source, lens system, and a screen to magnify and project the part onto a glass screen. The DRO is used to measure the displacement of the part.
