Motivation:
- a lack of information on what exactly happens during the chip formation at the primary and secondary shear zones as well as effects which take place under different process conditions
- difficulty to get an insight into the process and the mechanical loading due to the high temperature gradients and high plastic strain rates in the machining process
Aim:
- development of an improved methodology for chip formation simulation under ABAQUS/Explicit
- analysis of the influence of process and material parameters on the process values and stability

Results |
- modeling of the orthogonal metal cutting process
- development of remesh procedures
- comparison of simulations with the explicit and implicit solvers implemented in ABAQUS
- investigation of the influence of high friction coefficients by finite element simulations
- application of a new remesh method to the blanking process
