Chapter 6 Squareness Measurements in a Horizontal Plane
Positioning the Laser Head and Target Machine
Before you begin to assemble and mount the optics, you must position the
laser head and move the moveable part of the target machine to its start
position. Follow these steps:
This chapter uses a machine with a spindle as an example for making
squareness measurements. Although your machine may be different, the
general procedures described here still apply.
1
Position the laser head for the first axis measurement (Figure 6-4 or 6-5).
The way you position the laser head depends on whether the machine has
a vertical or horizontal spindle.
2
Adjust the laser head to the approximate height at which you will mount
the optics.
3
Determine how to position the optics. See Figure 6-4 or 6-5 for sample
setups, and use the following guidelines:
•
A machine with a vertical spindle typically has room to mount both
the reflector and the optical square on the table (Figure 6-4). If yours
does not, you will need to improvise some kind of table extension.
•
Typically, a machine with a horizontal spindle allows you to position
the laser head and optics as shown in Figure 6-5.
You are now ready to assemble, mount, and align the optical square and
interferometer assembly for the first axis measurement.
