K stands for the maximum of error when achieving equilibrium state.It has something to do with the weight and foundation materials of machine tool. α1,α2，α3 stand for changing rates of foundation.
Material ageing analysis The effects of material ageing on perpendicularity error can be expressed by the function as follows:

A framework for optimization of process parameters in material processing and production is described.
Several requirements must be met in order that the process runs smoothly and without defects in output material.
Together with chemical composition, this affects the final mechanical properties of produced material.
