How to avoid production errors and detect equipment wear in time
Manufacturing errors are expensive, especially when manufacturing parts that require high precision. A Nizhny Novgorod company that manufactures automotive components has found a way to detect wear on production equipment in advance. The methods described in this article are relevant for all segments of the automotive industry.
Since 2013, Antolin Avtotechnika Nizhny Novgorod has been manufacturing ceiling sound insulation elements for cars of world brands: Volkswagen in Nizhny Novgorod, Ford Sollers in Tatarstan and General Motors in Tashkent. Periodic monitoring of forming surfaces is part of a set of routine maintenance work to monitor and restore wear on technological or production equipment.
Geometry control can be carried out on contact CMMs, but this is a resource-intensive process. Specialists need to measure the curved surfaces of machines with a length of more than 2 m with a large number of control points. It takes several days to complete the task and receive reports, which is the time when the production line is stopped.
It is possible to get a quick and accurate equipment status report more efficiently with a Russian-made RangeVision PRO 3D scanner.
Algorithm for scanning large objects
Before starting the measurement, a matting spray must be applied to the object to eliminate the effect of glare from reflective surfaces. The use of self-adhesive contrast labels improves the accuracy of scanning and automatically aligns model fragments when digitizing objects with a uniform surface.The final STL model in the ScanCenter NG software is compared with the loaded reference design model. The result of the process is a color deviation map between the two models, which can be exported to a convenient format: JPEG, PNG, BMP or PDF.
RangeVision PRO is designed with specific production conditions in mind and uses blue backlight technology to offset the effects of bright ambient lighting. The 3D scanner allows you to obtain three-dimensional images of objects of various dimensions: from coins to the body of a car.
Advantages of professional scanning in the automotive industry
The introduction of the RangeVision PRO 3D scanner into the production process saves resources needed for product quality control. Scanning and processing of data on professional equipment is possible both in isolated cases, such as reverse engineering or custom manufacturing of parts, and in serial production of products.
Prototyping, development of new models, manufacture of interchangeable components and car parts, assembly line work and car tuning — 3D technologies are used at many stages of modern automotive production. Using the example of Antolin, we showed how RangeVision PRO saved time and optimized the solution to the problem.
