Novel machining technique reduces distortion in thin-walled parts by two-thirds.
Distortion in thin-walled bearing rings during machining can be controlled by using adapted non-circular finishing cuts. By adjusting the depth of cut based on geometric irregularities, deviations can be reduced significantly. The process helps compensate for material removal-induced deformations and uneven residual stress, leading to improved part shape and thickness consistency. The study found that the adapted cutting technique mainly affects axial residual stresses, without causing unexpected changes in part roundness during heat treatment. The compensation potential is highly influenced by how material removal alters the workpiece's deformation during cutting.
