1. A machine for tool working of plate-like metal workpieces, comprising a) a frame, b) a carriage mounted for movement on said frame along an X axis, c) a cross-member mounted transversely of said carriage for movement therewith, d) metal working means mounted for movement on said cross-member along a Y axis, e) first and second motive means for selectively driving said carriage and said metal working means along their respective axes, f) a support for receiving a template thereon, g) template tracing means disposed adjacent said support and having an output corresponding to the followed contour of the template, h) a coordinate drive control operatively connected to said template tracing means for actuating said motive means in accordance with the said output wherein i) a computerized numerical control (22) having a programmable memory, j) and feedback means (23, 24) connected to said motive means and outputting to said computerized numerical control (22) for loading said memory with positional coordinate information originating with said tracing means (13) and coordinate drive control (40) during following of a template (16), k) said memory having a selectively actuatable output to said coordinate drive control (40) to actuate said motive means (5, 11) and thereby work said workpiece (9) in accordance with the previously followed contour of the template (16) and independent of said tracing means (13) and with digitizing means (27) operatively connected to said template tracing means (13) for causing the latter to stop and sample the positional coordinates of the template contour (17) at selectively variable discrete spaced points depending upon the curvature characteristics of the said contour (17). |
