Abstract
A laser cutting machine includes a platform and a motion system. The motion system includes a first prismatic joint facilitating a first motion of the platform along a first direction and a second prismatic joint facilitating a second motion of the platform along a second direction. A galvano arranged on the platform, such that a motion of the platform causes a motion of the galvano, the galvano including a first mirror, wherein a third motion of the first mirror positions the laser beam along a third direction, and a second mirror, wherein a fourth motion of the second mirror positions the laser beam along a fourth direction. A control module controls concurrently the motion system and the galvano, such that a position of the laser beam on the workpiece is a vector sum of the first motion, the second motion, the third motion, and the fourth motion.
