In-line measuring system designed to can measure surface roughness

摘要

U.S.-based FocalSpec has introduced an automatic in-line roughness measurement system for wire, cable and filament extrusion applications in North America. A press release said that the company, which supplies optical high-precision 3D scanning sensors and solutions, now offers its Micro-Profiler MP 900 model. The non-contact model is based on FocalSpec's patented Line Confocal Imaging (LCI) technology that enables accurate in-production roughness measurement from a fast moving surface of any type and color. The system scans and analyzes a product's actual surface profile at the rate of 512,000 points per second. The maximum line speeds is 150 m/min (500 ft/min) and products with diameter of 1 mm (0.04 in.) to flat can be measured. The minimum reported Ra is 0.2 μm (8μ in.) and other standard roughness parameters, such as Rz, can also be calculated. Roughness of the product is displayed in real-time and operators are automatically alerted for abnormal process changes enabling instant corrective actions. All roughness results from the entire length of each produced reel are stored in the system's database for quality certification and production reporting purposes.
