Working pieces by laser beam
First Claim
1. Process for machining a workpiece by the use of a cutting tool having a cutting edge and an adjacent leading face which lifts shavings from the workpiece material, the process including the localized heating of the workpiece material about to be removed by means of a laser beam arranged to heat two distinct local areas of the workpiece adjacent the cutting tool:
- a first area immediately in front of the cutting edge of the tool and a second area adjacent the leading face of the cutting tool in a part of the workpiece material which is deformed plastically by the tool in the formation of a shaving.

Abstract
A laser-assisted machining process for the machining of materials which are normally difficult to work employs a laser source and associated reflecting means which focus the laser beam onto two distinct areas of the workpiece material to effect localized heating thereof and assist the formation of shavings by a cutting tool: one area is immediately in front of the cutting edge of the tool and the other is adjacent the leading face of the tool, in part of the workpiece material which is deformed plastically by the tool in the formation of a shaving.

3. Apparatus for the machining of a workpiece, comprising:
-
a tool holder, a cutting tool carried by the holder and having a cutting edge and an adjacent leading face which in use of the tool lifts shavings from the workpiece material; support means for a workpiece to be machined; means for effecting relative movement between the workpiece and the cutting tool, a laser source for generating a laser beam, reflecting means in the path of said laser beam for converging the beam to two distinct local areas in the workpiece material to be removed by the tool, in proximity to the cutting edge of the tool. - View Dependent Claims (4)
