... grains on the grinding wheel are subjected to heavy load during the grinding process, and the effective life of the grains is an important affecting factor in the performance of the grinding wheel. Fig. 4 demonstrates the grinding wheel wear characteristics under the two grinding processes when grinding wheel speed v s = 25 m/s and MRR = 2 mm 3 /(mm·s). As shown in Figs. 4a-c, a mechanical clogging pore with a lot of chips is obvious in area under CG, and continuous chip adhesion can be observed on the surface of the abrasive grains in ...

This study is a continuation of previous studies; therefore, the idea is to determine the influence of surface roughness and hardness on the bendability of a UHSS grade, and it is investigated with 3-point bending tests, utilizing Digital Image Correlation (DIC) for measuring the strain distributions on the outer curvature. Investigated bending sam...
The purpose of induction-heating-assisted ultrasonic surface rolling process is to introduce the temperature field into the ultrasonic surface strengthening process of materials and use the influence of heating temperature on the mechanical properties and microstructure of the material so that a surface-modified layer with improved performance can...
Nickel-based high-temperature alloys (Inconel 718) are considered to be difficult-to-machine materials with high yield strength and high-temperature strength properties and are widely used in the aerospace industry. Due to the low thermal conductivity of Inconel 718 material, it leads to severe machining hardening and easy to cause tool wear. In th...
