Decreasing the FRF peak magnitude, via increasing the tool damping, yields an
               enhancement in its stability limit. The SLD’s of ISCAR's anti-vibration tools and corresponding
               conventional tools are compared in the figure below, where ISCAR's anti-vibration
               tools show a considerably higher stability limit than that of conventional tools.

               Tool stiffness and mounting rigidity also affect the FRF and the stability limit of the tool.
               Increasing the mentioned stiffness will cause improvement in the FRF and stability limit.
