Evalaution and optimization of laser cutting parametersfor plywood materials

Abstract

Laser process parameters influence greatly the width of kerfs and quality of the cut edges. This article reports experiments on the laser plywood-cutting performance of a CW 1.5 kW CO 2 Rofin laser, based on design of experiments (DOE). The laser was used to cut three thicknesses 3, 6 and 9 mm of plywood panels. The process factors investigated are: laser power, cutting speed, air pressure and focal point position. The aim of this work is to relate the cutting edge quality parameters namely: upper kerf (UK), lower kerf (LK), the ratio between upper to lower kerfs and the operating cost to the process parameters mentioned above. Mathematical models were developed to establish the relationship between the process parameters and the edge quality parameters, and special graphs were drawn for this purpose. Finally, a numerical optimization was performed to find out the optimal process setting at which both kerfs would lead to a ratio of about 1, and at which low cutting cost take place.

“…Terkait parameter multi respon tersebut beberapa penelitian telah ditujukan untuk material plat logam (metal sheet) [9], logam yang lebih spesifik berjenis stainless steel [10], dan bahkan lebih spesifik lagi berdasarkan ketebalan stainless steel tersebut [11]. Selain logam, material lain dalam penelitian terkait optimasi proses cutting adalah kayu [12], plastik polimer [13], bahan polimer yang lebih spesifik yaitu polikarbonat [14], dan bahkan material komposit seperti Al6061/SiCp/Al2O3 [15].…”

Analysis of the influence of cutting parameters on surface roughness in laser cutting of tungsten alloy using control charts

“…Laser cutting parameters such as power, speed of cutting, pressure of assist gas and focus position are examined while cutting different type of materials using CO 2 laser system. Optimization is done using numerical and statistical methods [7,8]. The use of the CO 2 laser ensures better process characteristics during cutting of low-carbon steel sheets, while the use of the fibre laser is more effective for cutting stainless steel sheets with nitrogen used as a process gas [9].…”
