Chapter 7  Squareness Measurements in a Vertical Plane
Introduction
7-2 Measurements Reference Guide
Introduction
This chapter explains how to make squareness measurements in a 
vertical plane. These measurements allow you to determine if two 
machine axes are oriented, and move, perpendicular to each other. An 
example of a machine with two perpendicular axes is a Coordinate 
Measurement Machine (CMM) with a probe that moves vertically, 
mounted on a bridge that moves horizontally.
Chapter 6, “Squareness Measurements in a Horizontal Plane,” explains 
how to determine if two machine axes that are perpendicular to each other 
in a horizontal plane are oriented, and move, perpendicular to each other.
Before performing the procedures described in this chapter, you must fully 
understand and know how to perform the procedures presented in the 
Agilent 5530 Getting Started Guide.
For operating specifications for squareness measurement optics, see 
Appendix A.
Figure 7-1 shows the required hardware for squareness measurements in 
a vertical plane.
