REM’s industry-leading isotropic superfinishing technology, the ISF ® Process, is the specified surface finishing/surface polishing process for a wide range of aerospace power transmission and aero-engine applications because of its exceptional performance benefits; its proven process reliability and repeatability over decades of processing. The technological feasibility of the isotropic superfinishing (ISF) process, applied to Ti-6Al-4V parts produced by electron beam melting, is investigated in this paper by considering the dimensional and geometrical deviations induced by the finishing treatment, and from observations of the surface morphology. With applications in Formula 1, NASCAR, Indy Racing, SCCA Racing, Open Wheel Cart Series, and many other racing series, REM is the pioneer of surface finishing/polishing for the Racing/Motorsport industry and the company you should trust to. The surface finish of gear teeth is directly related to the service life and overall quality of aerospace gearing. Isotropic superfinishing was applied to the third stage spur bull gear and mating pinions along with the second stage bevel gears of a Sikorsky S-76C+ main gearbox. The gear was processed to achieve an isotropic finish by using the chemically accelerated vibratory finishing technique. Step three: Return the instrument to shop-floor. In-depth temperature measurements were made across the face width and at the axial end of the gear mesh. “The Effect of Superfinishing on Gear Tooth Profile” Report 2284; contract N68171-96- C-9043 (1997) 9.
