Abstract

Abrasive Water Injector Jet Cutting (AWIJC) is a flexible machining process for manufacturing high-performance materials, such as titan- and nickel-base-alloys. Due to the low ductility and thermal conductivity of these materials, conventional machining is struggling with high tool costs and wear. The tool wear in AWIJC is independent of the machined material, and the process has the potential to provide a cost-efficient solution in machining high-performance materials. Trimming, a near-net-shape pre-contouring with multi-stage AWIJC, requires a detailed knowledge of cutting paths for all steps in advance. In order to enable a geometrical flexible manufacturing process, an automatically cutting path generation is necessary. This article presents an application developed with NX Open using Visual Basic. The application TrimCAD is able to provide all necessary geometries for trimming based on the geometries of initial and finished parts. Furthermore, it is possible to adjust the number of cuts and the degree of pre-contouring. All geometries are automatically exported as a standardized three-dimensional STEP-file. The STEP-geometries can be processed to the CAM-processor of the waterjet machine. TrimCAD is an innovative possibility to machine three-dimensional parts made of high-performance materials.

水射流切边三维预轮廓切割路径的自动生成

磨料水喷射切割(AWIJC)是一种灵活的加工工艺，用于制造高性能材料，如泰坦和镍基合金。由于这些材料的低延展性和导热性，传统的加工正在与高刀具成本和磨损作斗争。在AWIJC中，刀具磨损与加工材料无关，该工艺有可能为加工高性能材料提供经济高效的解决方案。修剪，与多阶段AWIJC的近净形状预轮廓，需要提前所有步骤的切割路径的详细知识。为了实现几何柔性制造过程，需要自动生成切削路径。本文介绍了一个使用Visual Basic开发的NX Open应用程序。TrimCAD应用程序能够根据初始和成品零件的几何形状提供所有必要的几何形状。此外，还可以调整切割的数量和预轮廓的程度。所有几何图形都自动导出为标准化的三维step文件。step几何图形可以加工到喷水机的cam处理器上。TrimCAD是一种创新的可能性，可以加工由高性能材料制成的三维零件。
