Control method for reducing errors prosessing of the SLS machine

Abstract

This article presents a method of the error reducing control in SLS machine. When using SLS machine, there are many factors that cause the errors such as: temperature, trajectory, velocity and laser intensity. Therefore, we need to have a precise method control in order to have an accurate processing sample. This one presents the Fuzzy Control Method to help we achieve highly accurate results when process with SLS machine. We propose control method that establishs the criteria based on many influence processing parameters previously mentioned (*) rather than merely control position, velocity, trajectory as the CNC machines. The processing by SLS machine basse on the control MIMO model. Therefore, estimating and parameterizing control parameters to reducing.
