【Abstract】 The principle of a new grapnic method for solving the radius of curvature of planar cam con-tours is studied in this paaper.Based on this principle,the radius of Curvature of a cam contour can be easi-ly solved throuhg graphic methed.Several examples are also presented to illustrate how to use the methed. According to the geometric and kinematic relationships in thphic solution,a set of eqtiaitons for numetrical solution can be derived .更多还原
