Material selection and product specification

Steel material is supplied in two product forms – 'flat products' (steel plate and strip) and 'long products' (rolled sections either open beams angles etc or hollow sections) For structural use in bridges these products are inevitably cut (to size and shape) and welded one component to another In the structure the material is subject to tensile and compressive forces Get price

Cut the Chatter

Apr 01 2001Milling Cutter Chatter Use cutters with fewer inserts Although it may seem counterintuitive the first step to reducing chatter in milling operations is to switch to a cutter with fewer teeth In general the coarser the cutter pitch the lesser the chance of harmonic vibration Sometimes replacing a 16-tooth cutter with a 12-tooth tool ends Get price
