Abstract
The control system of laser engraving machine based on ARM processor realize the precise control of the two-dimensional stepping motor and the laser head. This article focuses on the proposed stepping motor speed and trajectory control algorithm, and meanwhile, the speed control adopt linear acceleration and deceleration control algorithm; Trajectory control, based on the traditional point by point comparison arc interpolation method, puts forward the improved algorithm which can effectively improve the interpolation speed and interpolation accuracy. The experimental results show that the method can improve the machining precision and machining efficiency of laser engraving machine, and also can realize the high precision carving.
