JETmill - Pre-contouring of hard to machine materials using abrasive waterjets

本研究的目的是扩大基础知识，创造一个高的纵横比和小的不规则性，在创造自由形式的切口基地的切口基地。研究的重点是二次射流的影响。挑战在于，这种效应的大小取决于所制造的几何形状。此外，将根据第一个资助期获得的知识创建与工件表面成一定角度的凹口。此外，该角度将在工件上的移动期间改变，从而产生作为位置的函数的角度。这种角度的变化将对后刀面的形貌产生重大影响。将开发经验模型，利用实验设计，从第一个供资期开始扩展现有模型。实验将在先前研究中使用的材料钛铝化物Ti 45 Al-5 Nb-0.2C-0.2B（TNBV 5）上进行。

The goal of this investigation is to expand the basic knowledge for creating notches with a high aspect ratio and small irregularities in the notch base in terms of creating freeform notch bases. The focus of the investigation is on the effect of the secondary jet. The challenge is that the magnitude of this effect depends on the geometry that is manufactured. In addition, notches with an angle to the workpiece surface will be created based on the knowledge that was gained in the first funding period. Furthermore, this angle will be changed during the movement over the workpiece resulting in an angle as a function of the location. This change of angle will have a major effect on the topography of the flank surface. Empirical models will be developed to expand the existing models from the first funding period using design of experiments. The experiments will be conducted on the material titanium aluminide Ti 45Al-5Nb-0.2C-0.2B (TNBV5) which was used in the previous investigation.
