Dressing strategy and grinding control for cylindrical microstructural surface

Abstract

Surface structural texture is designed to achieve specific functional performance for many advanced applications. After a brief review of current manufacturing methods for textural surface, this paper focuses on the study of microstructural surface creation by grinding. The axial and peripheral cross-sections of textured wheels under different dressing overlap ratios Ud are illustrated. A set of microstructural texturing models are proposed and the influences of dressing and grinding parameters are discussed. The texture formation is analysed in considering each cutting point in grinding kinematic movement. A significant effect of the grinding contact length on the texture formation is noticed, which defines a texture pattern limitation for grinding to manipulate. Typical surface texture characteristics are introduced to assess the structural surface features and the corresponding theoretical models are validated by experimental results. The relationships between the textural gouge size and the kinematic conditions of dressing and grinding have been delineated for the guidance of grinding texturing strategy. The component waviness on textured components clearly shows the importance of rotational ratio on the layout of microstructural texture. The paper lays down an important foundation for surface microstructural texturing by grinding.
