Cut Depth

An experimental investigation was conducted using a CO2 laser to cut fibrous insulation blankets for the Space Shuttle and high speed aircraft. This investigation was unique in identifying important factors for controlling the cut depth, thus, allowing the laser to be used for making partial cuts in a composite quilt. The investigation determined an algorithm for essential physical parameters used in automating the laser machining of these materials.

Laser has been employed for producing the complex specimens very efficiently and magnificently. The use of acrylic components is becoming prevalent day by day. Hence it is required to study the various machining techniques for engraving or cutting of acrylic material. The one of the non-traditional machining processes which can be employed efficiently for machining of acrylic is CO2 laser machining. The parametric study of acrylic materials by using CO2 laser machining is discussed in this paper. The scanning speed and the laser power were considered as process parameters and the influence of these parameters is studied on the depth as response measure. The engraving depth is observed to be increasing with increase in power and noted to be decreasing with increase in the scanning speed.

Laser beam cutting is a non-contact, production-flexible and highly productive technique that allows accurate profiling of a wide range of sheet materials. To these and further benefits, laser machining is increasingly being adopted by industry. This paper investigates the effect of material type, workpiece thickness, cutting speed and assistant gas pressure on cut quality for industrial-relevant applications using a CO2 laser. AlMg3 aluminum alloy, St37-2 low-carbon steel and AISI 304 stainless steel were selected to represent the most established materials in many industrial fields and gain insight into different processes (i.e., inert-assisted fusion cutting and oxygen cutting) and absorption behaviors with respect to CO2 laser wavelength. The aim was to enhance the understanding of the mechanisms through which laser cutting parameters and workpiece parameters interact in order to identify general criteria and well-optimized process parameters which guarantee the kerf quality. The quality of laser cut was analyzed in its basic terms: kerf geometry, surface roughness and cut edge quality. The experiments were performed by using a systematic experimental design approach based on Design of Experiments, and the results were validated via Analysis of Variance. Quality assessment was presented and discussed. The visual inspection of cut sections confirms good overall quality and limited presence of laser cut imperfections. The experimental investigation demonstrates that the different materials can be successfully processed within a wide range of the tested values. In addition, optimum cutting conditions which satisfy the straight requirement of the quality standard adopted are identified for each material. This study involves an analysis of both phenomenological and practical issues.
