Abstract:
A laser cutter system, comprising:a laser beam outputting device movably positioned relative to a worksheet for outputting a laser beam to fabricate said worksheet, said device superposing over said worksheet; motor means for driving said device; and processing means for controlling said motor means for moving said device to locations over said worksheet for fabricating said worksheet, said processing means calculating the movements required for optimally moving said device between said locations by a) establishing a focal distance that varies in response to changes in the vertical distance separating said device and said worksheet between said device and said worksheet; b) determining the focal distance separating said device and said worksheet; c) determining the distance separating a location on said worksheet above which said device is and the next location on said worksheet above which said device is to be moved to; d) determining the optimal movement for said device to get from said location to said next location; e) using said optimal movement to move said device to said next location after said location is pierced by said laser beam output from said device; and f) repeating steps a to d until all locations to be pierced on said worksheet are pierced.
