ABSTRACT:
A method for laser machining parts from a strip comprises providing a strip of material from which parts are to be made, feeding the strip into a laser station having first and second lasers, and positioning the first laser with respect to the strip. With the first laser, the method then includes laser machining substantially all of an outline of a plurality of parts in sequence along the strip, leaving at least one tab portion connecting each part to the strip. The second laser is then positioned with respect to the strip and, with the second laser, the method then includes laser machining tab portions connecting parts to the strip in sequence along the strip, and separating the laser machined parts from remaining portions of the strip. Preferably, the first laser and the second laser move simultaneously in the same direction with respect to the strip during laser machining.
