Abstract

See full text

A method is described in which only oneWorking point or action point on the tool, which in thegeneral can be a grinding wheel with the factoryin contact during the machining processstands. This one working point is also within theSelect the work area on the grinding wheel variablybar and can be predetermined in a zone with a fixedor variable radius of the grinding wheel.This is done by at least one in addition to those per seknown feed movements in the essentiallyMachining process working according to the partial rolling methoddrive performed feed movement in generalthe grinding wheel. I.e. the point of contact betweenThe grinding wheel and workpiece do not move on the grinding wheeldisc according to the rolling feed movements, soncan be kept in a predeterminable rangewill. In addition, however, it is possible to get aoptimal use of tools to achieve this workpoints targeted and preprogrammed, i.e. controlledrelocate. This operating point can be done according to the procedurealong different work lines, for example littleat least approximately from producers or at least approximatelyfrom flank lines, which can be helical lines,be performed. Devices for this process will bespecified.
