R&D on Laser Scanning Manufacturing Control System

The paper presented the actions and data communication among the components of LSM. There was nonlinearity mapping between output coordinates and scanner sphere coordinate and scanner driver in LSM. And it brings about nonlinearity errors of manufacturing geometry model. The control system was founded based on analysis of LSM technological speciality. The control system concerns the distance of the two swaying mirrors, the distance between the swaying mirror and convex lens, the mirror swaying angle, the lens focal length, the lens central height, the lens convex radius and the medium refractive index. It improved the precision and reduced the errors in LSM system. Modularization design ideology was adopted in the control system of LSM system. It reduced the difficulties of programming, shortened the design recycle while enhancing the stability of control system and the speed of manufacturing process. And complexity of software was predigested, program structure was perspicuity and easily comprehended, link-port was simply.
