摘要： The momentum look into researches the thermal stress investigation and temperature distribution of laser power 10.0w and 20.0w in aluminum oxide ceramic. Additionally, this paper explores the impact of thermal stress analysis and temperature distribution on material removal prepare. At the point when laser is connected for machining process for making smaller scale groove, temperature distribution assumes an imperative part for that since large amount of heat release by the laser which is influenced the material and deliver a heat affected zone thus material gets melted and vaporize. Thermal Stress is likewise being done because of nearness of thermal impact in material at the time of heat generation and it additionally assumes a decent part to achieve the great material removal handle. Accomplishing a fancied score of particular measurements is conceivable by having control over process parameters of a laser grooving machine which thus represents the measure of material removed. To handle with this, and concentrating on current trend where laser machining is exceptionally Demanded and connected in industry like like bio medical engineering, aerospace, automobile etc., and so on., it is particularly fundamental to concentrate the temperature distribution in the heat affected zone of the material where heat is created (due to heat energy released by laser beam) and equivalent thermal stress in the material body that is in charge of material removal, Achieving a desired groove with great precision. Limited component examination technique utilizing ANSYS is utilized to to simulate and analyze this temperature distribution and equivalent thermal stress of different laser power. In this paper temperature distribution FEM chart with diagrams for 10.0W and 20.0W, Material removal for 10.0W, 20.0W, Equivalent stress FEM diagram with graph for 100W, 200W are appeared furthermore the correlation of laser power in the vicinity of 10.0w and 20.0w are available.
