<p>A sheet of metal (2) is moved through a press (13) to separate components and scrap. The sheet is displaced by a feeder (11) following a predetermined co-ordinate pattern. Machining follows consecutive y-sections (24,26), each y-section (24) being fully machined in the x-direction before the immediately subsequent y-section (26) is positioned for machining. Machining is within areas (33) of length in the x-direction so that, after the first cut, a peripheral unbroken scrap portion remains and is severed by a second cut. A programmable control unit determines tool movement as required.</p> |
