Precision gear manufacturing is the process of producing gears whose spatial dimensions require an infinitesimal degree of accuracy. Consequently, the gears are typically produced with the help of elite technologies that ensure the parts attain the highest degree of accuracy.
One of these technologies is laser scanning, which uses laser scanners to capture the spatial data of an object, and implements processes such as CGI motion to ensure that integrated pieces work harmoniously.
For many types of gears, using laser scanning in the production process is a necessity and not a luxury.
If the parts are manufactured based on improper data, they may cause a safety hazard that exposes the producer to a lawsuit or results in a massive recall, not to mention the financial loss that comes from waste pieces and rework. Laser scanners help keep these problems from occurring and make them easy to identify and correct when they happen.
The Impact of Laser Scanning
In precision gear manufacturing, laser scanners are typically used in one of two capacities: for reverse engineering heritage parts, or for gathering the data of a newly designed part by scanning a model of the part. In either case, the scan data is translated into computerized data models to analyze the spatial data of the part.
With the help of three data models that represent scan data – polygon mesh models, surface models, and solid CAD models – engineers can ensure that gears are flawless on the first production run.
Polygon mesh models are used for contemplating the design of an object; surface models are used to model the object's surface, and solid CAD models — whose parametric features can be edited by changing a data value – are used to finalize design parameters.
