Chapter 5 Straightness Measurements
Introduction
5-2 Measurements Reference Guide
Introduction
This chapter explains how to make straightness measurements that allow
you to determine if a machine’s moveable part is moving along a straight
path. 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
straightness measurement optics, see Appendix A.
Straightness and squareness measurements are usually done together,
since a squareness measurement is actually two straightness
measurements perpendicular to each other.
The procedures in this chapter explain how to make straightness
measurements only. Follow them in the event that you are not going to
combine straightness and squareness measurements.
If you plan to make straightness and squareness measurements, you can
perform the straightness measurements as part of a squareness
measurement. Depending on whether your measurements are in a
horizontal or vertical plane, go to either Chapter 6, “Squareness
Measurements in a Horizontal Plane,” or Chapter 7, “Squareness
Measurements in a Vertical Plane.”
Figure 5-1 shows the required hardware for straightness measurements.
