Laser beam machining is a thermal energybased advanced machining process in which material is removed by focusing the laser beam on the work surface at a constant distance to melt and vaporize the unwanted work material. The main advantages of laser beam machining are ease of automation for complex cutting patterns absence of tool wear and.

Laser beam machining lbm is a non conventional machining manufacturing process a form of machining in which a laser is directed towards the work piece for machining.
Tolerance of laser beam machining. In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. It is used to machine both metallic and non metallic material. In this process a laser beam of high energy is made to strike on the workpiece the thermal energy of the laser gets transferred to the surface of the wp workpiece. It is based on unconventional machining techniques using laser beam electron beam electric arc etc. In this post you learn what is laser beam machining its working principle parts advantages applications and limitations. Precision may be better since the laser beam does not wear during the process. The laser is electromagnetic radiation. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. It is a non conventional machining process in which no tool is used. If you are going to invest in a laser cutting machine you should not only consider that process step but also how you embed the machine in your factory to get the best results from your investment as indicated in the previous section laser beam power shouldnt be your only metric in deciding. Laser beam machining is a thermal machining process which uses laser beam to produce heat. Dalam kehidupan sehari hari lbm biasa digunakan sebagai alat untuk memotong atau melubangi material dengan akurasi yang tinggi. It produces monochromatic light which is in the form of an almost collimated beam that can be focussed optically on to very small spots of less than 0002 mm dia. Laser beam machining lbm is a form of machining process in which laser beam is used for the machining of metallic and non metallic materials. Laser beam machining lbm yang akan kami bahas dalam makalah ini.
Advantages of laser cutting over mechanical cutting include easier workholding and reduced contamination of workpiece since there is no cutting edge which can become contaminated by the material or contaminate the material. Laser beam machining lbm state of the art and new opportunities johan meijer university of twente enschede the netherlands abstract an overview is given of the state of the art of laser beam machining in general with special emphasis on applications of short and ultrashort lasers. Lbm menggunakan sinar monokromatik berkekuatan tinggi sehingga alat ini hampir bisa digunakan pada segala jenis material. Non conventional machining is a recent development in machining techniques.
