be covered is analyzed and the influence of coefficient of judgment is studied through changing the design parameters. Key words: face-gear; surface contact area; singularity of worm; integrity of tooth..., the worm within the effective width cannot cover the whole working surface of the face-gear, that is, only part of the working surface of the face-gear is covered. Hence, the grinding integrity of face......

Key words: Si3N4; silicon nitride ceramic; laser surface processing; surface integrity; flexural strength; fracture origin 1... by a CO2 laser to remove the machining-induce defects. The surface integrity (henceforth, this refers to cavities and fracture areas), flexural strength, and fracture origins of the Si3N4 samples after......
Effect of shot peening and grit blasting on surface integrity: Influence on residual stresses K.TOSHA1, LU Jian2 1. Department of Mechanical Engineering, Meiji University, 1-1-1...: The influences of factors such as particle size (0.55-2.2 mm), particle velocity (15-35 m/s) and thickness of work material on the surface integrity were investigated. The residual stresses induced by shot......
