Methods Employed In Laser Tooling

It was not too many years ago when lasers, and their associated electronic targets did not exist. Alignment then was achieved by sighting between a near point and a distant point and then deciding if something placed in this line of sight was off either to the left or to the right or up or down from the sight line. Laser alignment in Texas is now common, and the answers to these critical questions are far more accurate.

The process of choosing two reference points is still the most important aspect of making a survey for straightness. A simple example is the survey of a big machine. The reference points which are used to determine the line of sight are taken off the machine, with these reference points, should the machine ever move position; all the measurements would be wrong.

In the past, a transit or alignment levels were used, the problem is the human interpretation of the results. The measurements were taken by putting a scale on the machine and reading the results off this scale. The scale, often called a rod is held by one man while the other man sights the transit and reads from the scale marked on the rod. It is a two-man job, difficult to teach the skills needed and not all that accurate.

Laser alignment in Texas has not only solved the problem with straightness, it also has solved the problems associated with squareness. Often during machine installation or calibration, it is necessary to establish a 90-degree angle. With laser alignment methodology, a penta-prism is used. This unique prism can be mounted anywhere because it has a very useful property; rotation around the axis of the prism does not turn aside the beam which is reflected.

The next application for laser alignment is to determine any error in alignment between two unique line of sight datum’s. The typical application for this test is the alignment of two shafts. The shafts can be offset laterally and angular. The shafts are considered as the two LOSs, the light source is set on one shaft and the target set on the other. Readings are taken and the shafts are rotated a full half turn, or 180 degrees. A second survey is done and the difference between the two results is twice the shaft offset. Once the out of alignment is known, getting it right is a simple task.

There is little room left for doubt. Laser alignment in Texas reduces errors during the installation, maintenance and calibration of large machines, including numerically controlled machine tools that must sit accurately on their base to provide the precision required in modern manufacturing.
