...Luanxia Chen; Lizhi Shang; Zhanqiang Liu; Swarnava Mukherjee; Yukui Cai; Bing Wang The cylinder block/valve plate interface is one of the major power loss sources and main failure points in axial piston pumps and motors. Surface micro-texture has been proven to be an effective approach to reduce...

... feed force and shear strength of the work material and was compared with the results provided by an analytical model. The experimental–numerical approach can be considered more accurate due to the fact that it considers the effect of the tool–chip interface temperature on the shear strength of the work...

... interface could further decrease the COF compared to those that are in the plane parallel to the interface. This may be due to the weaker adhesive ability, smaller real contact area, lower temperature, and higher anti-shearing ability on the interface. This work provides guidelines for the extension...
