Title The Scanning Control Method and Development of Forming Device by Selective Laser
Abstract
Selective Laser Melting(SLM) was proposed by the German fraunhofer institute in the mid-1990s.It is an important part of the rapid prototyping technology.SLM shows favorable prospects in the aerospace, automotive, medical, mold and other fields. Due to the high requirement on the accuracy and stability, the control system of the scanning selective laser melting forming device is always a hot research at home and abroad.
Based on the development demand of new SLM materials such as ceramic, composite and others, this issue developed a SLM forming control software. The software is compatible with the forming equipment of our lab. The main research work including:
(1) The SLM forming principle, the working principle of vibrating mirror system and need of the conventional ways of scanning for new materials research’s need were mastered;
(2) We did the requirement analysis for the SLM control software, planned out the function modules, and designed the program interface;
(3) We coded according to the designed interface, realized the function of software modules respectively, and then realized the function of the entire program required of all;
(4) We did a connection test for the program and the forming device, and used a simple experiment to verify the validity of this software.
