Computer-Aided Manufacturing of Laminated Engineering Materials (CAM-LEM), developed at Case Western Reserve University, is a layered-manufacturing approach utilizing automated stacking of parts laser-cut from sheet materials. This paper presents the design of a materialhandling system and its integration with a modular lasercutting system, completing the most recent version of CAM-LEM. Our mat...

This paper reports a statistical analysis of the laser wood cutting process. The laser cutting of wood is a multi-factor process and correct combination of the parameters involved is needed to achieve high quality and optimum process efficiency. In this paper a design of experiments and statistical modelling approach is used to investigate the significant process parameters by consideration of ...

Quality improvements in laser cutting of mild steel have been achieved. by a newly developed model-based optimisation strategy. The specific aims of such efforts are to assure quality of cut when cornering. Such routines encompass a large proportion of all features processed on laser curting systems, and therefore their successful production is paramount. Associated with cornering is the elevat...

A potassium-titanyl-phosphate (KTP) laser through robotic endo-wrist instrument has been evaluated as an ablative and hemostatic tool in robotic assisted laparoscopic partial nephrectomy (RALPN). Ten RALPN were performed in five domestic female pigs. The partial nephrectomies were performed with bulldog clamping of the pedicle. Flexible glass fiber carrying 532-nm green light laser was used thr...

AImtrm--The quality of a laser-made cut is of the utmost importance in laser processing. Any improvement in this area would be of considerable significance, in that it would lead to an elimination of post-machining operations. Currently the mechanisms governing the laser cutting process are not fully understood, partially due to the fact that laser cutting is a highly complex thermal process. I...

The main goal of this thesis is to document the design and testing of various components for use in a low cost laser cutting mechanism for hobbyists and recreational designers. Different electronics were used to assess the cutting potential of a laser diode, a small silicon chip based laser light producing unit. A test rig was constructed to evaluate the cutting potential of the laser diode, an...
