STATIC STIFFNESS CALCULATION OF A LATHE HEADSTOCK
Keckstein T., Pušman Š., Hynek M.
pages 289 - 292, full text

Checking and calculation of the headstock static stiffness for every machine tool is important because it directly influences the machine accuracy, which is one of the most important factors. This paper describes the calculation and results of the static stiffness of a bearing housing in different areas of the headstock of a universal centre lathe. To determine the stiffness, we performed a calculation using the finite element method (FEM). The computational model was loaded by maximum forces that were calculated via analytic calculations. Displacement of several important areas of the headstock was found by using this FEM calculation. Stiffness was calculated from displacements and loading forces by using well known formula.
