In response to the problems of high axial force and severe edge collapse at the outlet during the drilling process of zirconia ceramics,a diamond coated drill bit with a diameter of 0.2 mm was used to drill fully sintered zirconia ceramic micropores.Through a single factor experimental method,the effects of spindle speed,feed speed,and step distance on axial force were studied.Based on this,a comparative experiment of pecking drilling technology was conducted,preliminary exploration was conducted on the influence of variable feed pecking drilling process on the size of outlet edge collapse.The results show that the axial force increases with the increase of feed speed and step distance,and first decreases and then increases with the increase of spindle speed.The use of variable feed pecking drilling can effectively improve the hole export processing quality.
