Dry Machining Tool Design via Chlorine Ion Implantation Atsushi Mitsuo1,Shinji Muraishi2,Shigeo Yamamoto1,Tatsuhiko Aizawa3,Taro Sumitomo3 (1.Tokyo Metropolitan Industrial Research Institute, Tokyo... of lubricous oxide films is found to be effective for dry machining. Through the chlorine ion implantation to tools, titanium base oxides are in-situ formed on the tool surface.This oxide deforms elasto......
pin profile has resulted superior mechanical properties in the welds. MUGADA and ADEPU [24-26] studied the role of tool shoulder profile and pin profiles and identified that each shoulder has... of high compatibility of shoulder-driven flow and pin-driven flow developed by knurling shoulder tool and square pin profile. Figure 9(d) shows a mixed flow region along the welding line due......
and forging load were investigated on the thixoforging of non axis-symmetric parts of steel grade X210CrW12. The experimental and numerical study of the material flow and tool temperature load reveal the areas of intensive tool wear, thus being useful for further tool design. Hardened hot working steel X38CrMoV5-1 as a tool bulk material with protecting thin films of TiAlN/g-Al2O3 shows good......

New Tool Coatings for Light Metal Cutting Wei-Ming Sim1,Quanshun Luo2,Dave Doerwald3,Papken Hovsepian2,Thomas Krug3,Roel Tietema3 (1.Airbus, Bristol, United Kingdom;2.Sheffield Hallam University.... These coatings can be used either directly on the tool or as topcoating combined with another hard base coating. Cutting tests show that the coating gives good performance for materials that tend to stick......

by surface-resolved computational fluid dynamics (CFD) simulations. To obtain this information, an efficient bubble profile reconstruction method based on an improved agglomerative hierarchical... obtained by a surface-resolved CFD simulation. Application results indicate that the proposed method is effective even when the data include some non-uniform and distortion. Key words: bubble profile......
A novel friction stir diffusion bonding process using convex-vortex pin toolsS.D.Ji1,Q.Wen1,Z.W.Li21. College of Aerospace Engineering, Shenyang Aerospace University2. State Key Laboratory..., excellently bonded at the lap interface and without hook, were obtained. The lap interfaces on the joints welded using the T-tool and F-tool almost remained intact, thereby indicating that they were formed......
