3. bias curve method described in claim 2, is characterized in that performing step is as follows:
A. consider that face gear grinding process is to use the one-sided processing characteristic that carries out of emery wheel, the emery wheel profile to need finishing, carries out parametric modeling by software, makes the outer bias curve of the 1mm of its side that need repair;
B. on bias curve, by required precision, get series of points, the movement locus of the broken line of usining by these points during as finishing;
C. by software, obtain the coordinate data of these points, and calculate the relative coordinate of every point-to-point transmission, thus the G code of acquisition this section of broken line under relative coordinate.
4. bias curve method claimed in claim 2, is characterized in that technological parameter is as follows:
Trim process parameter is grinding wheel speed 1200r/min, and roller rotating speed 480～840r/min repairs total cutting-in 0.2mm at every turn, single feed cutting-in 0.02mm, feed speed 1.5～2.5mm/s.
5. emery wheel claimed in claim 2 (8), is characterized in that: finishing is R1 by cutting edge part radius of corner, roller diameter 100mm, thick 22mm.
