In this paper a model of the feed drive system with disturbance force for High
Speed Cutting (HSC) linear motor machine tool tool is given. The dynamic stiffness for the
proposed model is analysed. A simulation of the influence of some parameters on feed drive
dynamic stiffness is performed with the simulation program MATLAB & SIMULINK.
Correctness of the proposed model is verified with an experimental measurement of the dynamic
stiffness of the feed drive on the prototype HSC linear motor machine tool (HSC 11)
