Transition from Stable Laser Fusion Cutting Conditions to Incomplete Cutting Analysed with High-speed X-ray Imaging

High Speed Thin Metal Cutting using Fiber Laser Technology

There are several methods available for precision cutting of thin metals less than 0.06-inch thick used for these applications, which include materials such as stainless steel, titanium, nickel, and aluminum. The major options, lasers, electric discharge machining (EDM), water-jet, and chemical machining each have a role to play. However, precision fiber laser cutting technology is now emerging...

Manipulator motion planning for high-speed robotic laser cutting

Recent advances in laser technology, and especially the essential increase of the cutting speed, motivate amending the existing robot path methods, which do not allow the complete utilisation of the actuator capabilities as well as neglect some particularities in the mechanical design of the wrist of the manipulator arm. This research addresses the optimisation of the 6-axes robot motions for c...

High Speed Laser Cutting of Electrodes for Advanced Batteries

Lithium-ion batteries are at the forefront of current advanced battery technology development for Hybrid-Electric Vehicles (HEV). While first vehicles with Li-ion batteries have entered the market, it is understood that significant technology advancements are still required to establish consumer confidence in the new battery technology and to reduce battery cost for serving a broader market. Th...
