As shown before, many parameters other than the nano-hexapod itself do influence the plant dynamics:

• The micro-station compliance (studied here)
• The payload mass and dynamical properties (studied here and here)
• The experimental conditions, mainly the spindle rotation speed (studied here)

As seen before, the stiffness of the nano-hexapod greatly influence the effect of such parameters.

We wish here to see if we can determine an optimal stiffness of the nano-hexapod such that:

• Section sec:spindle_rotation_speed: the change of its dynamics due to the spindle rotation speed is acceptable
• Section sec:micro_station_compliance: the support compliance dynamics is not much present in the nano-hexapod dynamics
• Section sec:payload_impedance: the change of payload impedance has acceptable effect on the plant dynamics
