ONE-SIDE MACHINING PRINCIPLE AND NEW
TYPE OF POINT CONTACT OF THE GLOBOIDAL CAM*
Abstract: A new cutter’s control method is produced, which realizes the one-side machining of the globoidal cam. A example is presented, and the result shows the new method has great practical value. A new type of point contact mechanism is presented, a hyperboloidal roller replaces for the cylindrical roller in assembly, the point contact with hyperboloidal roller overcomes the defects of linear engagement and enhances the mechanism’s toleration of and adaptability to error. Using the method can help to improve the positioning and indexing accuracy and whole performance of the mechanism.
