A quality controlled laser-chemical process for micro metal machining

Abstract: A laser-chemical process combines advantages of both laser ablation and electro-chemical machining and is used to produce free form micro forming tools. The desired geometry results from a sequence of overlapping removal paths with different cross section. Due to the high requirements of geometry accuracy and surface roughness, a three-level quality control system is developed for this process. Based on causal analysis between removal profile and process parameters a post-process controller designs the positio… Show more

“…Factors such as laser-energy absorption dynamics, heat accumulation, chemical reactions, and hydrodynamic transport phenomena cause various disturbances during the material removal process of laser chemical machining (LCM) [Zha15]. In order to achieve competitive shape and surface quality in applications such as rectangular micro-forming dies, where the produced bottom surface requires a certain flatness and roughness, control of the workpiece manufacturing is imperative.…”

“…Thus, laser chemically machined geometries can reach structure sizes between 10 and 400 lm, depending on the laser-focus diameter, with steep slopes and a surface roughness of up to 0:3 lm [14]. The fluctuating process environment however, caused by chaotic thermal interactions between fluid and workpiece geometry, complicates the determination of optimal process parameters to produce a desired geometry [19]. To avoid time-intensive preliminary experiments, a closed-loop quality control has been designed to improve both the manufacturing speed and quality of laser chemical machining [18].…”
