Abstract:
In the manufacturing process of cylindrical cams with numerically controlled milling machines, the programming as well as the machining of accurate profiles normally turn out to be problematic. In an effort to overcome some of these problems the machine tool builder, MAHO (Germany), had during 1990, supplemented its numerically controlled units with an option with which cylindrical interpolation is made possible. With this option programming is considerably simplified in some cases, but serious limitations necessitate in many instances that the option cannot be applied at all. The limitations of the option and how to overcome them, are illustrated and discussed in a typical programming example.
