A flexible topological flank modification method based on polynomial interpolation function

Topological modification of gear surface is used to achieve better meshing transmission performance and accuracy. However, in the traditional grinding process, topological modified tooth usually simplified control profile lead modification, which difficult coincidence machining design. To solve this problem, a flexible topology flank method based on polynomial interpolation function proposed paper. Based principle technology, realizes by controlling multiple axes’s position machine tool. Firstly, model worm wheel with controllable precision established. Then axial, radial tangential motions expressed as fifth order polynomials, coefficients optimized particle swarm optimization algorithm. Finally, numerical simulation was compare sensitivity matrix method, results showed that had effect. The new can realize motion each axis tool, problem does not match design solved.
