【Abstract】 Some key theories and techniques in the grinding of camshaft part by using the method of tracing tangent point grinding are discussed, A mathematical model describing the relationship between the displacement of grinding wheel center and the rotational angel of camshaft is established. According to the principle of constant speed of grinding points, the mathematical model concerning the relationship between the rotate speed and the rotational angel of the camshaft is presented as well. Finally, some suggestions on the optimization of the rotate speed of the camshaft are introduced on the basis of the experimental results.更多还原
