This paper presents a method for calculating the surface roughness in the direction of the workpiece rotation and the grinding wheel cross-feed when grinding carbide punches by diamond wheels with a multi-layer composite electrolytic coating. Relationships between the longitudinal and transverse components of the surface roughness and the cutting conditions are considered: grinding wheel rotational speed, workpiece rotational speed, cutting depth, and cross-feed of the wheel. A method is proposed for determining the cutting modes that provide a reduction in roughness in the longitudinal and transverse directions. Cutting conditions for diamond grinding of a carbide punch are defined and experimentally tested. The surface roughness parameters Rmax = 0.12 mkm and Ra = 0.03 mkm are confirmed.
