Effect Of Preheating On The Thermal Microstructural And

Ebm can be used for very precise cutting or boring of a wide variety of metals.

Parameters of electron beam machining. In this process a laser beam. The welded assembly exhibited a minimum amount of distortion but a better understanding of the effects of several key welding parameters on the structural integrity of the weld was required. Electron beam machining ebm ebm equipment equipment is contained in vacuum 10 4 mm hg or more in order to ensure cutting energy. This is why machining fragile and brittle materials is obtainable using this method. Surface roughness heat affected zone haz recast layer etc. Rayate pg student kkwagh institute of engineering education and research nasik maharashtra india. Parameters are determined to yield the desired product quality and also to maximize the process performances. In lbm there are many factors such as beam parameters material parameters and machining parameters which affects the various quality characteristics eg. Abstract laser beam machining lbm is one of the most widely used thermal energy based non contact type advance machining process. A pulsating stream of high speed electrons produced by a generator is focused by electrostatic and electromagnetic fields to concentrate energy on a very small area of work. Power consumption is exceptionally high but applications at the moment are very specialized and the normal machining parameters have little significance. An electron gun is basically a triode consisting of. Control parameters optimization of laser beam machining using genetic algorithm ruben phipon1 bbpradhan2 1 mechanical engineering department smit sikkim india. Multi objective optimization of laser beam machining process parameters pj. As electron beam machining is grouped under the thermal category it is natural to have thermal damages as part of the result.

The electron beam can be controlled very accurately and machining tolerances of 0005 mm are possible. Electron beam machining ebm electron beam machining is a thermal nontraditional process uses electrical energy to generate thermal energy for removing material. Electron beam machining does not apply any cutting force on the workpiece thus very simple work holding is required. Electron beam welding was used for joining al6061 t6 precision machined cylindrical sections. Electron beam machining ebm is a process where high velocity electrons concentrated into a narrow beam are directed toward the work piece creating heat and vaporizing the material. Electron source is an electron gun several times the intensity of a tv gun.
