SUMMARY:Webinar: Shop Floor Surface Finish Measurement with 3D Optical Gauges
DESCRIPTION:Join us on Wednesday\, April 2\, 2025\, from 12:00 p.m. to 1:00 p.m. EST\, to learn how you can take advantage of our rugged\, portable roughness system to provide 3D surface finish measurements with nanometer resolution right on the shop floor. \n REGISTER > \nUntil now\, companies have typically relied on 2D stylus-based systems or expensive\, non-portable optical profilers that can be time consuming and extremely sensitive to environmental factors\, typically confining them to extremely quiet vibration-isolated lab environments. Optical profilers have the added burden of being stationary and therefore limited in sample sizes and geometries that can be measured. \nThis exclusive webinar demonstrates how to take advantage of our rugged\, portable roughness system to provide 3D surface finish measurements with nanometer resolution right on the shop floor. \nThe 4Di InSpec® SR employs patented technology for rapid surface measurements unaffected by vibration. \nYou’ll learn how to beat the most difficult metrology challenges: \n\n3D roughness of hard-to-reach areas and large samples\n3D roughness in any orientation – right on the shop floor\nAutomating 3D roughness measurements\nIntegrating 3D roughness systems into process machining systems\n\nSee firsthand how user-friendly the 4Di InSpec® SR is with live demonstrations measuring various industrial samples manually. \nWith a roughness accuracy of better than 0.5% and its small\, portable form factor\, the 4Di InSpec® SR can measure in any orientation on applications including: \n\nAviation & aerospace parts such as engine rotors\, turbine blades\, shafts\, and gears\nAutomotive parts including engine cylinders\, cranks\, bores\, gears\, brake pads\, and EV batteries\nMedical implants\nPrecision machined surfaces\nPrecision bearings\nShot peen surfaces\nIn-situ precision machining (grinding\, polishing\, lapping)\nAdditive manufacturing\nSemiconductor bare and processed wafers\n\nWho should attend this webinar? If you’re in these fields: \n\nAerospace\, aviation\, MRO\, medical device industries\nParts manufacturing\nMachining or 3D printing\nInspection and qualification\nEngine / component repair\nMetrology labs
