Solving a Base Bound Problem (21 KB)

Summary
In a base bound situation the movable machine (Motor) is sitting high, but there are no shims under the feet. The problem can be solved by raising the front of the stationary machine (Pump).

Introduction to laser roll alignment (2.3MB)

Summary
Laser roll alignment is one of the high-value applications of lasers in a web process. These materials will cover the basic concepts so you fully understand roll parallelism, as well as the benefits. They go on to clearly illustrate how to use a laser system to perform roll parallel measurements.

Rough Alignment Procedure (33KB)

Summary
Rough alignment is one of the recommended pre-alignment procedures. A straightedge is suitable for the horizontal rough alignment. But to expedite the vertical rough alignment it is recommended that one not make guesses about the amount to shim. This procedure provides an easy method for calculating the amount to shim...

Roll Alignment with Fixturlaser Roll 200 (4.7MB)

Summary
The Fixturlaser Roll 200 was the first complete laser system dedicated to roll parallel measurements. This presentation covers some fundamentals that apply to all laser systems and in a detailed fashion builds up to the more complex roll parallel measurement. Plenty of illustrations and actual pictures bring the measurement and its benefits to life.

Measuring Straightness (1.2MB)

Summary
One of the fundamental geometric constructs is a straight line. Here we define straightness and show how to use a laser to measure deviations from a straight reference (the laser beam).

Measuring Flatness (1.9MB)

Summary
A key requirement for erecting most machinery is that one starts with a flat base. There are also other machine features and production processes that require flatness (eg. Rolls in a machine, forming section in paper making). These highly illustrated materials will define flatness and show how to use a laser system for measuring flatness.

Straightness - rotational center as reference (1.1MB)

Summary
The straightness measurement is one of the most basic measurements that can be accomplished with a laser system. These materials define straightness and illustrate how to use a laser system to make a straightness measurement with a rotational center as the reference. This version of the straightness measurement can be used whenever there is a rotational center to be designated as the reference (eg. Crankshaft of an engine, etc.)

Straightness - 2 points of reference (1.0MB)

Summary
The straightness measurement is one of the most basic measurements that can be accomplished with a laser system. These materials define straightness and illustrate how to use a laser system to make a straightness measurement with 2 points of reference. This type of measurement has wide application in industry.

Roll alignment presentation at American Institute of Steel Engineers meeting (3.5MB)

Summary
This is the PowerPoint presentation used at the Southwest regional meeting of the American Institute of Steel Engineers. It covers the use of lasers for performing roll parallel measurements. In addition, it has good information on early roll parallel methodologies such as tram rods and optical transits.

Accurately Measuring Machinery Movement (2.1MB)

Summary
All machinery moves as they go from off-line to on-line. Most of this movement is usually attributed to thermal growth but in fact restraining points and process forces can contribute significantly to these changes as well. This presentation will explore the phenomena of dynamic movement and how to properly measure the total movement of machines in order to perform true precision alignment.

Straightness - bore center to a rotational axis (289KB)

Summary
The straightness measurement is one of the most basic measurements that can be accomplished with a laser system. These materials define straightness and illustrate how to use a laser system to make a straightness measurement with a rotational axis as the reference. This version of the straightness measurement can be used whenever there is at least one rotational centerline involved (eg. Bearing pockets in an engine, bores on a compressor, etc.)

Straightness - center of bores as reference (1.1MB)

Summary
The straightness measurement is one of the most basic measurements that can be accomplished with a laser system. These materials define straightness and illustrate how to use a laser system to make a straightness measurement with a bore as the reference. This version of the straightness measurement can be used whenever there is a machined bore to be defined as the reference (eg. Bearing pockets in an engine, bores on a compressor, etc.)

New laser technique for measuring dynamic movement (1.4MB)

Summary
Laser shaft alignment was introduced over a decade ago. Since then there have been incremental improvements to laser shaft alignment systems. The OL2R Fixtures represent the most profound innovation in the field of precision alignment since the introduction of laser alignment. The OL2R Fixtures (patent pending) employ virtual centerlines to precisely measure the total movement of machinery.
