Ww. Mcknight et al., UTILIZATION OF CNC MACHINING CENTER AS A 3-DIMENSIONAL COPY MILL, Journal of materials processing technology, 43(1), 1994, pp. 61-64
This paper describes manufacturing procedure utilised by Crossen Engin
eering for the manufacture of non-geometrically defined three dimensio
nal components. The requirement was to produce a press tool for the ma
nufacture of a three-dimensional sheet-metal component identical to a
hand-produced sample. No geometrical drawing specification was availab
le for the component.
