Novel negative lattice point engraving process

The invention discloses a novel negative lattice point carving process, and relates to the technical field of carving. The novel negative lattice point engraving process comprises the following steps of 1, adjustment, specifically, oblique lattice points are deformed into positive engraved parts of negative lattice points by adjusting the angle SA of engraving oblique line job, the pulse length of PL and FOC vector control parameters; step 2, partial carving: parameters of LAC and DC are adjusted, and when a numerical value needing to be carved is adjusted, the negative carving part of the negative lattice point is carved; 3, readjustment is conducted, specifically, the light emitting angle AJ of the carving machine is adjusted to the smooth degree of the bottoms of the lattice points, and new negative lattice points are obtained; and 4, carving is conducted, specifically, a place needing to be carved is subjected to work through a carving machine, after carving is completed, the surface is polished to 6 u th
