Luggage on the laser's edge.

LVD Co NV, a Belgium-based manufacturer of CNC press brakes and shears, hydraulic presses, laser cutting systems, and turret punch presses, has designed and built a laser system for cutting magnesium alloy extrusions used for luggage frames.

The SAM 1000 laser system was supplied to Samsonite's Oudenaarde, Belgium plant for production of frames for the company's premium Spectrum line of suitcases. The magnesium alloy frames posed a special metalcutting problem because of the large size of holes and grooves relative to the thin magnesium extrusion. Production was further complicated by delicate slots and holes that had to be cut in the frame.

On first sight, the five-axis machine seems to have little in common with LVD's traditional large, flat laser cutting systems. An upright C-frame with a rotary head on top is mounted on the worktable. The piece being worked can be positioned and turned, but the cutting head also moves vertically, using sensors to follow the outline of the frame.

The machine's working envelope measures 40" X 40" X 36". The unit is equipped with a 1500-watt C|O.sub.2~ laser, and has a positioning speed of 23 ips on X, Y, and Z axes with precision of 0.004" in 20".

LVD's latest addition to laser cutting of flat sheet is the Impuls 3020, a flying-optic machine with X, Y and Z travel of 80", 120", and 10", respectively. the Impuls 3020 uses a 1500-watt C|O.sub.2~ laser, and can handle sheet and plate materials up to 0.5" thick.
