tResidual stresses have an important role concerning service life of forming tools. The grinding of the toolis one of the major manufacturing steps inducing residual stresses into the subsurface of the tool. Tooland process parameters for grinding with toric grinding pins have been investigated for their influenceson residual stresses and surface finish. Residual stresses were measured using the sin2 method, whilethe surface finish was analyzed using white light confocal microscopy. Results show that the grindingstrategy has a major influence on residual stress generation for both principle directions of the process. Inaddition cutting grain size has the major impact on residual stresses transverse to cutting direction, whilefeed rate has the main influence on residual stresses in cutting direction. A bigger grain size results inmore compressive residual stresses, while a higher feed rate shifts stresses towards the tensile regime. Agood surface finish is achieved with small cutting grain size, low feed rates and frontal grinding strategy.
