Paper Abstract

This paper is devoted to the arrangement of trajectory of the laser beam by scanner and plotter systems. The problem appears only when the trajectory changes from one direction to the other. The motion along direction 1 to point A and along direction 2 after point B can be provided by the same speed V1 equals V2 equals V*. But between the points A and B it is necessary to make some manipulations to provide the same quality of the irradiated zone -- the width d, the accuracy (Delta) (maximum deviation from the desired trajectory), momentary values of energy intensity q, W/cm2, etc. The general way to hold the constant value of q, which defines the temperature of irradiated zone for laminated objects manufacturing (LOM) and selective laser sintering (SLS) and photons density for stereolithography (SL), is to control speed of motion of scanners and plotters. We discuss an approach for optimization of control algorithms for both types of delivery systems.
