3D laser surveying and utility mapping London are known to benefit manufacturing companies during the engineering and reverse engineering processes. But laser surveying also benefits manufacturers by allowing them to perform top of the line quality service inspections. Although the primary focus of manufacturing is engineering and producing flawless products, defective products can result from more than defective design; they can also result from defective manufacturing equipment whose flaws are hidden to the eye.

One way that a company determines whether product design, or flawed production equipment is responsible for defective product is to compare a product’s as-built data to its solid CAD model data. If the as-built data is the same as the design data, the fault lies within the design; if the as-built data differs from the design data, the fault likely lies within the production process. In either case, laser surveying presents Gwalia Surveyors with at least three quality inspection report types which include,

1. Color map Deviation

Color map deviation presents a computerized product model that uses various colors to indicate product defects. Often, these flaws don’t present a danger to consumers, but they can mean that a product won’t live up to its warranty. For example, color-map deviation is often used to reveal part war page, a phenomenon where products don’t function as indicated due to one or more warped parts. An example of how part war page could compromise product quality is a smoke detector that doesn’t close properly.
2.Cross Section Analysis

Cross section analysis can be performed anywhere on a product and compares cross sections of as-built objects and as-designed CAD models. Cross section analysis performs 2D analysis on certain locations of a model and reveals deviations using a color gradient reference system. Cross section analysis is commonly used when part thickness must be verified, when a certain cross section shape is desired and to further incorporate design intent into an as-built model.

3.Geometric Dimensioning and Tolerancing

Geometric dimensioning and tolerancing is commonly used to compare as-built models to as-designed CAD models to test concentricity, angularity and circularity. Geometric dimensioning and tolerancing is ultimately concerned with the tolerance elements of a product’s design with regard to safety and durability, and is expressed as a symbolic language in engineering drawings and solid CAD models. In scientific terms, geometric dimensioning and tolerancing determines the allowable variation of product geometry in terms of maintaining design durability.
