ABSTRACT:
Method of removing stock from difficult to machine workpieces comprising directing a first laser beam (LB.sub.1) at a workpiece along a first axis to produce a first kerf. A second laser beam (LB.sub.2) is directed at the workpiece along a second axis which intersects the first axis to produce a second kerf. Relative motion is effected between the workpiece and the laser beams whereby the intersecting kerfs produce a separate solid removable portion (14) from the workpiece.
