Abstract:
A data generating device for generating numerical control data for controlling the operation of a cutting tool when machining an article, comprising:geometric data input means to which a set of geometric data representing a shape of said article to be machined is input; partial geometric data generating means for dividing the set of geometric data into a plurality of sets of partial geometric data each representing one of a plurality of article parts constituting said article to be machined; a plurality of partial numerical control data generating means for generating from said sets of partial geometric data sets of partial numerical control data for machining article parts represented by the partial geometric data; and numerical data unifying means for generating a set of numerical control data for machining the whole of said article to be machined by unifying the plurality of sets of said partial numerical control data; wherein each of said article parts to be machined is formed as a layer extending in a direction perpendicular to a cutting depth direction of said cutting tool.
