Abstract

Segmented chips are often found in high-speed-cutting. This type of chip formation can be traced back to adiabatic shear bands. The reference workpiece material is the Nickel-based alloy Inconel 718, which shows an affinity to segmented chip formation. A realistic simulation of the chip formation and of the related cutting forces and chip temperatures serve to better process understanding. By implementing a material model into the FE-simulation which besides strain, strain rate and temperature includes ductile damage, a realistic description of the material behavior becomes possible. The results of the experiments and of the 2D- and 3D-simulations correlate well.

    In addition, an initial analysis of the global model in Fig. 13 (a) was performed by applying the node-based submodeling technique provided by ABAQUS to consider the overall stiffness of the hydraulic manifold block in the simulation results, and then repeated simulations were implemented by applying the previously estimated 30 J-C model parameter sets to the submodel corresponding to a major region of interest where the plastic deformation and cutting occur as shown in Fig. 13 (b) [93]. In the removable region expressed in the green part in Fig. 13 (b), the cutting of the hydraulic manifold block by the staking tool was realized by applying both the J-C constitutive model and failure criterion with the element deletion option [94–96]. A fracture energy of 40 N/mm was applied taking into account a minimum element size of 0.05 mm to reflect the damage evolution of the material in the removable region.
