Abstract
The surface contours generated in laser grooving by a compound jet nozzle on mild steels have been characterized experimentally and theoretically in this study A sidejet grooving nozzle was designed with various attacking angles to achieve the optimum conditions on the material removal rate and surface roughness for this technique The grooving depth was estimated through the formulation of the energy equations with the consideration of exothermic heat and the grooving contours were measured by the laser displacement sensor The results show a close agreement between the theoretical prediction and experimental testing The process characteristics and the parametric analysis were also discussed
