Abstract

See full text

A laser machining system (20) employs a fast positioner (68), such as a pair of galvanometer mirrors (70), that directs a beam axis (24) at a specified velocity to a start position of a cutting path (92) in coincidence with one of multiple laser pulses emitted from a laser (28) a constant laser pulse repetition rate, which runs independently of the relative position of the beam axis (24) with respect to the workpiece (26).
