Repeatability in Measurement – Why is it Important?

When speaking of measurements, accuracy is the topic that is most often discussed. But in fact, there is something equally important that is often overlooked – repeatability, otherwise known as precision. When measuring in industrial conditions, a service company can take alignment measurements with less than perfect instruments and achieve a specification of accuracy. Yet, [...]

Machine Alignment Increases Paperboard Mill Performance

A large paperboard mill in Ontario, Canada was having issues with baggy edges, wrinkles and lateral tracking problems (in cross-machine direction), particularly in the board machine’s coater area. These problems regularly caused sheet breaks 2 or 3 times a week, every time resulting into stopping the production for 2-4 hours. With each down hour costing between five [...]

The Versatility of Modern Metrology Devices

It is often a preconceived notion that precision is the defining strength of a measurement device.  While it is true that many applications require extreme precision and accuracy, other applications can simply benefit from the versatility of such devices. Laser trackers are portable coordinate measurement devices where in most applications their precision is called upon [...]

Location, Location, Location- Establishing Proper Alignment Foundations

One of the most common tasks involving machinery alignment is locating machine components during installation. The erection process of a large or complex machine can be a daunting task. In some cases, the process involves thousands of components that fit perfectly together on the design engineer’s CAD software, but in reality are subject to real [...]

Thermal Growth Studies Help Troubleshoot Issues in Turbo Machinery

Large and small machinery is susceptible to the effects of temperature variations due to fundamental properties of materials at the molecular level.  Basically, when various materials change temperature, they change dimensionally.  When the size of the components affected is considerable, the coefficient of thermal expansion of the material is high, and if there is enough [...]
