Waterjet Machining and Peening of Metals | Part 4 Summary and Conclusions

Summary and Conclusions An experimental study was conducted to determine the influence of material properties on the surface integrity and texture in WJ and AWJ machining of metals. Based on experiment, it can be concluded that waterjet peening with high-pressure jet is capable of inducing surface/subsurface work hardening. The resulting compressive residual stresses were comparable […]

Waterjet Machining and Peening of Metals | Part 3 Results and Discussion

Waterjet Peening. Figure 2 shows the typical erosion surface photomicrographs of water-peened specimens with different jet conditions. The erosion region resulting from the jet obviously varied with respect to the standoff distance ~SOD!, with it being narrowest and deepest at the minimum SOD. Removal characteristics within the impact zone were found to be predominantly dependent […]

Waterjet Machining and Peening of Metals | Part 2 Experimental Procedures

Materials. A number of common structural metallic alloys were used in this study, including Al 7075-T6, AISI 4340, AISI 304, Monel 400, molybdenum, and Ti6Al4V. These materials are used extensively within the aerospace industry and provide a large distribution in mechanical properties for study. The pertinent physical and mechanical properties of the metals are listed in […]

Waterjet Machining and Peening of Metals | Part1 Introduction

The development of high-performance materials, such as composites and advanced ceramics, presents a variety of manufacturing challenges. Many of these materials cannot be effectively or economically machined by conventional methods, and therefore require methods of shaping and/or postmold processing with unique sources of material removal. Various methods are currently used in machining and surface treatment […]
