The average mass of material removed per pulse me is related to the depth of material could be worn away per pulse ge as the equation gives where db is the diameter of the electron beam at contact with the machined surface and r is the density of the workpiece material.

Electron beam machining material removal rate. Meaning of electron beam machining ebm. Electron beam machining ebm advantages and disadvantages. Metal removal rate mrr in metalcutting is a volume of chips removed in 1 minute and it is measured in a three dimensional quantity. Out of all the non traditional machining methods electron beam method has the lowest material removal rate. Because the total setup is kept in an enclosure machining zone cant be seen by a machine operator. Turning equations machining time min t m m l f r t machining time min l length of cut f r feed rate inmin material removal rate in. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. 160000 kmsec focused stream of electrons which are focused magnetically upon a very small area. Slow rate of material removal. Mainly used for producing holes in the diesel injection nozzles. It is difficult to produce perfect vacuum. In this post you learn what is electron beam machining how its done with its working principle advantages of ebm accuracy and limitation of electron beam machining. Electron beam machining is the metal removal process by a high velocity focussed stream of electrons which heats melts and vaporizes the work material at the point of bombardment. Current formula 1 for. Working principle of electron beam machining.

Laser beam machining operates by directing the output of a high power laser at the material to be cut. Electron beam machining is a thermal process used for the metal removal during the machining process. Maximum material removal rate can be achieved in electron beam machining. Mrr is also a measure of productivity of metalcutting milling turning and drilling. In this process the material is removed with the help of a high velocity travelling at half the speed of light ie. What are the working principles of laser beam machining. Material removal rate is very low compare to other conventional process. The accuracy in calculating mrr is very important. This will generate high heat energy and melts and vaporize metal from work piece.
