使用液体射流切割的主要优点是灵活性和一致的锋利刀具，可以加工大量材料和复杂形状。不幸的是，部件的加湿对于某些应用是一个问题，并且抑制了喷射技术的传播。相比之下，使用液态二氧化碳（CO2）的喷射在干式和无残留物切割工艺领域提供了新的潜力。在最近的过去，一个原型系统的开发，它允许一个稳定的液体CO2射流的产生和分析。由于这一点，可产生的射流力，射流速度和切割切口取决于加工参数，如喷嘴直径，射流压力和喷射距离进行了研究。通过本出版物，将介绍为了实现具有竞争力的工业制造过程而进行的喷射修改和优化。在高达300 MPa的高压CO2射流的研究中，将分析不同材料的射流性能，并与普通水射流加工进行比较。因此，将特别研究工作距离的影响。主办单位：WJTA-IMCA
The main advantages of cutting with liquid jets are the flexibility and consistently sharp tool, which allows the machining of a large number of materials and complex shapes. Unfortunately, the humidification of the components is a problem for certain applications and inhibits the spread of jet technology. In contrast, jetting with liquid carbon dioxide (CO2) offers new potentials in the field of dry and residue-free cutting processes. In the recent past, a prototypical system was developed which allowed the generation of a stable liquid CO2 jet and its analyzation. Due to that, producible jet forces, jet velocities and cut notches depending on machining parameters like nozzle diameter, jet pressure and jet distance were investigated. With this publication the jet modification and optimization in order to achieve a competitive industrial manufacturing process will be presented. In the investigation on the jetting with highpressure CO2 with up to 300 MPa the jet performance on different materials will be analyzed and compared with the plain waterjet machining. Therefore especially the impact of the working distance will be investigated. Organized and Sponsored by WJTA-IMCA
