Aim. Development of mathematical model for process of teeth profiling of spur helical gear by disk cutting tool by the radial and round kinematic modify formation method on the basis conception of forming of teeth flanks by spatial helix coaxial formative lines. Method. Researches are based on methods and substantive provisions of the theory of parts surfaces formation by cutting instruments, in particular formation of spur gear teeth, the tooth system theory, kinematics analysis, analytical and differential geometry.
disk milling cutters
The processes of cutting indents provided functional descriptions of gear-wheels and this process are determine the technical or economic indicators of manufacturing processes by making the large modules gear-wheels. Effective direction by efficiency increase of these manufacturing processes is related to appli-cation the new gear cutting method radial - and - round formation (RRF) the continuous rotation of the cut gear-wheel purveyance.
