TREATMENT-COMPLEX PARTS SUCH AS BODIES OF ROTATION ON THE CNC MACHINES

Abstract

One of the most common complex profile parts such as bodies of rotation are the details from the screw surface. Typical of this type of parts are rotors of screw pumps. Existing methods of manufacturing rotors of screw pumps can be divided into two groups: methods based on the use of a turning tool, and methods based on the use of the axial cutting tool. For methods using a lathe tool, is characterized by low productivity and high wear of the cutting edge in comparison with an axial multiblade tool. However, most of the methods that implement the processing axis milling tool, based on the use of mechanical devices with sophisticated kinematics, which limits their application. This lack is not using CNC milling machines. The most time-consuming part of the process in the pre-production of screws in this equipment is the preparation of control programs
