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.

Research on Welding Process Simulation Training Technology Based on Virtual Manufacturing

“…Computer-aided manufacturing welding (CAW) technology, too, has gradually been able to effectively help design welded structures and joints, develop reasonable welding process plans, and manage the welding process using computer management software to improve production efficiency and quality. Kristian Arntz et al [4] used a computeraided manufacturing system to meet the processing needs for special laser process deposition welding, and provide solutions for the process chain of complex manufacturing and repair tasks for small quantities of high-value parts. While virtual simulation is mainly divided into Virtual Reality (VR), which is immersed in a virtual world to interact with virtual objects to achieve operations, and Augmented Reality (AR), which combines the real world with virtual objects to interact with operations.…”

Knowledge-Based Assistance System for Part Preparation in Additive Repair by Laser Powder Bed Fusion

“…Several authors address the process planning for additive repair using DED. For example, Arntz et al (2015) developed a system for computer aided manufacturing process planning for wirebased laser deposition welding. Therein, the laser path is determined based on the geometry of the machined part, which is digitized by a laser scanning process.…”
