Karabulut, AfyonKocatepe University, Faculty of Technology, Mechanical Engineering, Turkey Since competition has risen in the manufacturing methods of present conditions, the chance of competition has lost in the situations which new or high technologies aren’t exactly known. The proper selection is important for competing in the market conditions. In this study, the aim is to present the most advantaged cutting method for obtaining quality products by using high technology for gaining a better chance of competition. In the test, St 50 alloyed steel is used as sample. This sample is cut with the methods of laser, erosion and abrasive water jet (AWJ) among the cutting operations made with the high technology. The micro structure photograph of surface of sample, which is cut, are taken and the eff ects of diff erent methods of cutting on the metallurgical structure of material are compared. Also, changes are examined by performing the measurement of rigidity to the core from the edge of cutting. The most advantaged cutting method is presented by considering these examinations.
