Fluid Jet Polishing (FJP) and Slurry Jet Micro-Polishing use low-pressure premixed micro-abrasive slurries. Because the tool is compliant fluid, there is zero tool wear or thermal damage.
Prestonian Removal & Gaussian Footprint:
v_{jet} = C_v \cdot \sqrt{\frac{2 P_{slurry}}{\rho_{fluid}}}E(r) = E_0 \cdot \exp\left(-\frac{r^2}{2 \sigma_{spot}^2}\right)Sa(t) = Sa_0 \cdot \exp(-K_{decay} \cdot t_{dwell}) + Sa_{limit}
5-axis CAM toolpaths compute deterministic deconvolution dwell matrices to polish freeform aspheric optical glass, silicon wafers, and cobalt-chrome orthopedic joints.
