1. A laser assisted machining apparatus, comprising:

  • a lathe having a workpiece holder that spins about a rotational axis and a cutting tool holder that moves along a path parallel to said rotational axis of said workpiece holder;

    a first laser unit connected to said cutting tool holder so as to emit a first laser beam impinging upon a workpiece in said workpiece holder at a circumferential position about said rotational axis that is substantially ahead of that of a cutting tool in said tool holder;

    a second laser unit connected to said cutting tool holder so as to emit a second laser beam impinging upon the workpiecefrom an axial position behind the cutting tool relative to its travel direction along said path, andat a circumferential position close to and ahead of that of the cutting tool and substantially behind that of the first laser beam on the workpiece; and

    control means for independently controlling output of each of said first and second laser units.
