    This paper deals with performance analysis of disintegration of polymethylmethacrylate using pulsating
    liquids jet with different density with frequency 20 kHz using condition monitoring. The influence of the
    liquid on the cutting depth was studied by using contactless measurement device MicroProf, FRT. The
    cutting depths were compared to studies that used a continuous water jet to assess the volume flow
    reduction. On-line condition measurement was used for controlling the disintegration process without
    compromising the structural integrity of neighbouring materials. With a flow rate of 0.54 l/min, a maximum
    disintegration depth of 1.3 mm and material removal of 0.4 mm3 was obtained using physiological
    saline and 1.1 mmand 0.2 mm3 for water. Continuous jets required approximately 1.0 l/min to reach similar
    cutting depths. Hence, a pulsating liquid jet enhances the cutting capacity with reduced flow rate.
    Signal strength for individual pressures 7–10 MPa is not significant, but signal increases during significant
    bone cement removal. The results open new avenues for research a minimally invasive and nonthermal
    technique for on-line controlled processes for medical purposes.
