Computer aided manufacturing supported process planning of additive manufacturing by laser deposition welding

Abstract

Laser additive manufacturing technologies have to be integrated into sophisticated process chains including the computer aided manufacturing (CAM) process planning to achieve best overall performance. But currently, additive manufacturing processes are developed to their limits without regards to the CAM process planning. Based on integrated CAM software, which handles specific laser process needs, successful implementations focus on individual geometries and offer solutions for the entire process of complex manufacturing and repairing tasks in laser deposition welding. Due to the change of process conditions and requirements, adequate process strategies need to be developed. Therefore, the capability for controlling these process parameters is considered within the CAM system. Hence, the shortcoming of laser deposition welding, the machining strategies can be fitted to the part's geometry.
