Creep-feed grinding developed about the same time as high-speed grinding. Conventional grinding uses high work speeds and very small depth of cut. The concept with creep-feed grinding is to slow the work speed right down to allow deep cuts to be machined. Typical values of work speed are lower than 1 mm/s.Web
