Additive manufacturing and post-processing simulation: laser cladding followed by high speed machining

摘要: Additive manufacturing (AM) is a promising technology for many industrial sectors, from aerospace to personal care goods. However, when it comes high-quality components, CNC machining still the most reliable solution. A lot of research has been conducted modeling and predicting quality an additive manufactured or machined part. state art clearly indicates that short-term future will be mostly comprised process chains, which combine both subtractive processes. Taking this into account, paper presents methodology chain consisting laser cladding, as AM process, high speed (HSM), usually used finishing operations. The methodology, based on finite element method utilizes level set define cutting tool path, able predict results such residual stresses part distortion. proposed approach applied in simulating HSM steel tube fabricated by cladding. are showing can partially eliminate distortion caused
