<p>A method of removing material from a workpiece by directing a laser beam onto an area of the workpiece and at the same time injecting substantially continuously a stream of high speed (5-300 m/s) solid particles onto the area of the vicinity thereof. The solid particles may be aluminum oxide or zirconium oxide particles having a size in the range of 1-50 mum. The particle stream is preferably formed coaxially around the laser beam, the particles being accelerated by means such as an inert gas or electrostatic charge which does not work the material. The laser beam melts the material and the solid particles are directed into the molten material before exiting from the face of the material opposite that to which the stream is directed.</p>
