This book presents an innovative approach for piercing materials and shows how the application of computer software and correct setting of technological parameters in production are important tools for achieving the required production quality. Piercing of material is performed in practice for all types and thicknesses of materials, always within the residual material. This book shows how the AWJC piercing in material can be performed in a more productive way as is currently the case, bringing ultimate reduction of cutting costs, especially for cut material saving.
