Machinability of inconel 718 during turning: Cutting force model considering tool wear, influence on surface integrity

•Machinability of Inconel 718 is studied in finish turning conditions using carbide tools.•A mechanistic cutting force model is improved for round inserts.•A new local formulation is tested to take tool wear into account.•This original model is validated over a wide range of finishing parameters.•Residual stresses under the machined surface are studied depending on tool wear.
