Abstract

The invention relates to a sinusoidal cylindrical surface ultraprecise turning helical cutter path generating method, and belongs to the technical field of mechanical numerical control processing. AnZ axis is subjected to scale division; a sinusoidal cylindrical surface generatrix equation is obtained through derivation or the existing sinusoidal cylindrical surface generatrix equation is used; the sinusoidal cylindrical surface is subjected to radial part number division, so that the sinusoidal cylindrical surface generatrix is subjected to part number division around the axial line in the radial direction and rotates for a circle for obtaining the sinusoidal cylindrical surface; the sinusoidal cylindrical surface is subjected to screw pitch scale division in the radial direction; meanwhile, the screw pitch is subjected to cutter contact point track scale division; a helical cutter contact point cutter path is generated on the sinusoidal cylindrical surface according to the derived cuter contact path generation expression; the cutter radius r and a cutter radius compensating expression are selected; the helical cutter contact point cutter path is subjected to radius compensationto obtain the cutter location point coordinate value; the cutter location point coordinate value is converted into actual numerical control processing NC code. The method has the advantages that the processing efficiency of the sinusoidal cylindrical surface is favorably improved; the processing precision of the sinusoidal cylindrical surface is effectively improved.
