Laser bending is a promising technique utilised in order to deform metal sheets that offers the advantage of requiring no hard tooling and no external forces, thus reducing cost and increasing flexibility. Laser forming involves a complex interaction of many process parameters, ranging from those connected with the irradiation of the laser beam to those regarding the thermal and mechanical properties of the workpiece material. The present work is focused on the laser bending of AISI 304 steel sheets by using of a diode laser. The influence of process parameters, such as the power of laser beam and the scanning speed as well as the metal sheet thickness on the bending angle has been taken into account. The investigation has also analysed the effect of rolling direction of the metal sheets and the conditions of cooling on the bending process.

The present paper describes an experimental study on influence of process parameters on dross properties in laser machining of AISI 304 material. Process parameters namely laser power, cutting speed and gas pressure are considered in the present work. Design of experiments is done using response surface methodology and analysis of variance is performed in order to identify significance and influence of process parameters on dross height. It is found that laser power and gas pressure are most significant parameters followed by cutting speed. Dross height increases with increase in laser power and decreases with decrease in gas pressure. On the basis of experimental analysis, a second order mathematical model is developed to predict dross height. Model predictions and experimental results are found in reasonable agreement. Further, optimization of process parameters is also performed to minimize dross height
