The minimum stiffness of machine tools for ensuring the desired roughness of the machined surface of the workpiece

In the article the method of calculating the optimum modes of processing of working surfaces of machine tool parts. Submitted by the expert quality parameter, which allows you to calculate the discrete values of machine tool surfaces quality parameters details. It is shown that mathematical formalization of finding the minimum stiffness of machine tools on the set altitude parameters treated workpiece surface roughness. These techniques allow the article to design the machine accessories and other items of industrial equipment with minimal cost of their production.
