Notes:
The surface characteristics of Si3N4 ceramics milled with abrasive waterjet millingtechnology is studied. The milled surface characteristics and the effect of process parameters onmilled surface roughness are analyzed. The results show that the milled surface roughness rangesbetween 0.55 and 1.1um at the milling conditions under consideration and is changed with thechange of process parameters. The milled surface roughness will be significantly decreased at themilling conditions of lower water pressure and larger lateral spacing. The effect of nozzle traversespeed on milled surface roughness is complex, but a traverse speed of 1000mm/min is the optimumspeed for AWJ milling Si3N4 ceramics. The milled surface roughness first decreases then increaseswith an enhancement of standoff distance from 10mm to 30mm, and it also significantly decreaseswith the increase in abrasive mesh. Therefore, the medium standoff distance of 20mm and finerabrasive are the optimum conditions for AWJ milling Si3N4 ceramics with the process parametersunder consideration
