Title: Software development for Laser Engineered Net Shaping

Conference ·
OSTI ID:656769

Laser Engineered Net Shaping, also known as LENS{trademark}, is an advanced manufacturing technique used to fabricate near-net shaped, fully dense metal components directly from computer solid models without the use of traditional machining processes. The LENS{trademark} process uses a high powered laser to create a molten pool into which powdered metal is injected and solidified. Like many SFF techniques, LENS{trademark} parts are made through a layer additive process. In the current system, for any given layer, the laser is held stationary, while the part and its associated substrate is moved, allowing for the each layer`s geometry to be formed. Individual layers are generated by tracing out the desired border, followed by filling in the remaining volume. Recent research into LENS{trademark} has highlighted the sensitivity of the processes to multiple software controllable parameters such as substrate travel velocity, border representation, and fill patterns. This research is aimed at determining optimal border outlines and fill patterns for LENS{trademark} and at developing the associated software necessary for automating the creation of the desired motion control.
