磨料水射流足迹的建模是至关重要的，旨在生成受控的自由曲面。本文报道了无掩模控深铣削应用中射流轨迹（切口）的几何模型。该模型首先需要找到材料特定的侵蚀（蚀刻）率，该侵蚀率通过采用模型的限制条件（高射流进给速率）从射流足迹获得。一旦找到了这一点，就可以准确地预测任何射流进给速度的射流足迹。以SiC陶瓷为靶材料，以90 °射流冲击角为例进行了模型验证。(C)2010年CIRP。
Modelling of abrasive waterjet footprints is of critical importance when aiming to generate controlled freeform surfaces. The paper reports on a geometrical model of the jet footprint (kerf) in maskless controlled-depth milling applications. The model firstly needs to find the material specific erosion (etching) rate that is obtained from the jet footprint by taking the limiting conditions (high jet feed rates) of the model. Once this is found, the jet footprint can be predicted accurately for any jet feed speed. An example of model validation is presented for 90 degrees jet impingement angle against a SiC ceramic as target material. (C) 2010 CIRP.
