激光辅助喷射电化学加工（LAJECM）是一种混合工艺，它将激光束与电解液射流相结合，从而产生通过电化学溶解去除金属的非接触工具电极。激光束有效地提高了LAJECM的精度，因为它能够将溶解引导到特定的目标区域。这防止了由于杂散电流而导致的不需要的区域的加工。激光束与电解液射流的这种并行应用使得能够提高加工精度以及生产率。LAJECM已经表明，激光辅助加工可以有效地促进材料去除20，25，33和54%的哈氏合金，钛合金，不锈钢和铝合金，分别。由于更集中的加工（约20%），孔和腔的形状精度也有显著提高，表面粗糙度略有降低。对于铝合金、不锈钢、哈氏合金和钛合金，测得的锥度减小量分别为38%、40%、41%和65%。(c)2006年爱思唯尔公司All rights reserved.
Laser assisted jet electrochemical machining (LAJECM) is a hybrid process, that combines a laser beam with an electrolyte jet thereby giving a non-contact tool electrode that removes metal by electrochemical dissolution. The laser beam effectively improves the precision of LAJECM as it is able to direct the dissolution to specifically targeted areas. This prevents the machining from unwanted areas due to stray current. This parallel application of a laser beam with the electrolyte jet enables an improvement of machining accuracy, also productivity. LAJECM has shown that machining with laser assistance can effectively facilitate material removal of 20, 25, 33, and 54% for Hasteloy, titanium alloy, stainless steel and alummium alloy, respectively. There is also a noticeable improvement in the shape accuracy and slight decrease in surface roughness of the holes and cavities produced due to more focused machining (the order of 20%). The measured reduction in taper is of the order of 38, 40, 41, 65% for aluminium alloy, stainless steel, Hasteloy and titanium alloy, respectively. (c) 2006 Elsevier Inc. All rights reserved.
