Renishaw System Leads Cmm Scanning Out Of 'time Warp'

摘要

Renishaw says early adopters of its ultra-high-speed scanning system for coordinate measuring machines are achieving good productivity gains. At the heart of the Renscan5 system is the infinite-positioning REVO head. The system is being applied to complex parts that take long to manufacture.rnOne example is a jet engine blisk. The manufacturer had experienced a 922% throughput improvement, according to Renishaw. The inspection sequence comprises nine section scans of the airfoil profile, eight longitudinal scans of the blade, two scans of the rootrnprofile, and one scan of the annulus profile.rnWith conventional 3-axis scanning at 10 mm/s, it takes 46 min per blade, or 22 h, 14 min for all 29 blades. With the EVO head, scanning takes place at the rate of 500 mm/s for a per-blade time of 4 min, 30 s-2 hr, 10 min, 30 s for all 29 blades.
