Research of Crankshaft Grinding Wheel Dresser Based FANUC NC System

We used to crank connecting shaft neck in the center of the neck as the origin of work piece coordinate system. Through the offset of the work piece coordinate, we made use of the method of the coordinate value in keeping with the real coordinate diameter or the relative location value of the work piece center. We designed a kind of crankshaft NC dresser which consists of the Siemens servo semi-closed loop control system, imported servo motor drive and double axle linkage. In the process of machining, by coordinate origin migration to solve the change of coordinate for grinding wheel off after grinding wheel and decreased diameter. It realized the constant speed grinding wheel through the numerical control programming and NC grinding parameter Settings to realize the rotating speed of infinitely variable speed. Practice proves that the NC dresser simplifies the NC programming of the wheel molding, avoids the complex digital control and computational analysis software, and prevents the interference of dressing tools and grinding wheels.
