Method for evaluating quality of rough surface of sectile rod for internal combustion engine of car, involves defining set of items on rough surface, and determining slope between points of surface, where items form nodes of grid on surface
The method involves defining a set of items (18) on a rough surface (14), where the items form nodes of a grid on the rough surface. A slope is determined between two points of the rough surface. An irregularity of the rough surface is determined according to the determined slope, where the rough su...
