Thermal error regression modeling of the real-time deformation coefficient of the moving shaft of a gantry milling machine Adv. Manuf. (IF 2.568) Pub Date : 2020-02-21 Wen-Hua Ye, Yun-Xia Guo, Heng-Fei Zhou, Rui-Jun Liang, Wei-Fang Chen
This paper describes a novel modeling method for determining the thermal deformation coefficient of the moving shaft of a machine tool. Firstly, the relation between the thermal deformation coefficient and the thermal expansion coefficient is expounded, revealing that the coefficient of thermal deformation is an important factor affecting the precision of moving shaft feed systems. Then, thermal errors

Sensitivity analysis of the surface integrity of monocrystalline silicon to grinding speed with same grain depth-of-cut Adv. Manuf. (IF 2.568) Pub Date : 2020-02-15 Ping Zhou, Zi-Guang Wang, Ying Yan, Ning Huang, Ren-Ke Kang, Dong-Ming Guo
Mechanisms for removal of materials during the grinding process of monocrystalline silicon have been extensively studied in the past several decades. However, debates over whether the cutting speed significantly affects the surface integrity are ongoing. To address this debate, this study comprehensively investigates the effects of cutting speed on surface roughness, subsurface damage, residual stress

Parametric relationship between hypoid gear teeth and accurate face-milling cutter Adv. Manuf. (IF 2.568) Pub Date : 2020-02-06 Mahmoud Rababah, Muhammad Wasif, Syed Amir Iqbal
The cutter systems of hypoid gear cutting machines contain groups of inside and outside blades. In these cutter systems, the side cutting edges of the blades machine the convex and concave gear teeth while rotating about the cutter rotation axis. The side cutting edges lay on the rake face formed through the blade, rake, and relief angles; hence, the normal cross-section of the cutter swept surface

Fabrication and shape detection of a catheter using fiber Bragg grating Adv. Manuf. (IF 2.568) Pub Date : 2020-02-04 Xiang-Yan Chen, Ya-Nan Zhang, Lin-Yong Shen, Jin-Wu Qian, Jia-Ying Fan
Considering the spatial position and shape detection properties of the fiber Bragg grating (FBG) curve sensor used in the human body, the positioning accuracy of the FBG curve sensor plays a major role in the pre-diagnosis and treatment of diseases. We present a new type of shape-sensing catheter (diameter of 2.0 mm and length of 810 mm) that is integrated with an array of four optical fibers, where
