Considerable research studies were carried out to investigate the laser heating process.The analysis of acoustic sensing for laser grooving and cutting was carried out by Sheng and Chryssolouris .They introduced the process control scheme for groove depth and beam breakthrough regulation for laser cutting process.Surface temperature due to a moving laser beam was formulated by Romer and Meijer.They presented two types of approximating functions elating the scanning speed to the maximum surface temperature.Three-dimensional conduction model in relation to laser machining process was introduced by Modest.He predicted the shape of a developing groove that was formed by ablation of material by a stationary as well as moving laser beam.Temperature field during laser forming of sheet metal was examined by Ji and Wu .They employed finite element method when solving the governing equation of heat transfer.They showed that temperature gradient in a depth below the surface increased with increasing of laser power and workpiece thickness while it decreased by laser beam scanning velocity.A dual gas jet laser cutting process involving co-axial and off-axial oxygen gas flows was investigated by Hsu and Molian .They showed the effectiveness of the dual gas-jet in achieving the maximum machining rate without deteriorating the cut quality.The turbulent boundary layer approach allowing chemical reactions for CO2 laser oxygen-assisted cutting process was introduced by Yilbas and Sahin .They showed that heat transfer to the liquid metal decreased with increasing workpiece thickness.The thermal analysis of laser cutting process was studied by Yilbas .He indicated that the mathematical model employed presented the physical phenomena well,with the limit of characteristic distance,striation frequency and striation width,as predicted,agreeing well with the experimental findings.A numerical study for CO2 laser cutting process was carried out by Yilbas .The melting front velocities at different laser output power and workpiece thickness were predicted.
