CUTTING ANGLE AND SHAPE ANALYSIS TO INCREASE PRODUCTIVITY IN ROLL SHEET METAL CUTTING

Abstract

Today, the use of rolled sheet metal materials in the automotive industry is quite common. These sheets are subjected to many processes such as cutting, bending and drawing. However, in order for these processes to be realized, first of all, the coil sheet metal must be cut to form the desired dimensions. The unusable part of the coil sheet metal that remains after the process is called "scrap". During the pressing of the coil sheet metal, the sheet metal is required to be placed in the press mold in the desired dimensions and position. In the cutting process of the coil sheet metal, the amount of scrap caused by the cutting geometry is of great importance, because less scrap indicates that the cutting process is performed efficiently. In this study, the efficiency of coil sheet metal cutting process was investigated. The optimization of the coil sheet metal cutting geometry designed with the help of CAD (Computer Aided Design) program was carried out in a virtual environment with CAE (Computer Aided Engineering) programs and compared with the cutting method used in the enterprise. As a result of the study, it was concluded that it is appropriate to perform the cutting process at 60° and in the infill pattern cutting geometry, where the least amount of scrap is released. This research provides important information to improve the efficiency of sheet metal coil cutting. Performing cutting operations with less scrap can save costs and reduce environmental impacts in the industry.
