Special Issue Information

Dear Colleagues,

In order to improve manufacturing productivity, product quality, and to reduce cost, the use of cutting process simulations represents a real alternative to the empirical experimental approaches (trial/error) often used in the industry. The introduction of new products requires the development of an appropriate production solution. Process models can be particularly important for use in process planning systems for machining processes. Predicting how the material removal affects tool and workpieces in machining processes is an efficient way to assist manufacturing industries to optimize the cutting conditions and to guide the tool design.

Modeling of tool–chip interaction allows analyzing the coupling between the work material behavior, the tribological conditions at the tool–workpiece interfaces, and the process parameters (cutting speed, tool geometry, tool coatings, material removal rate, etc.). The aim is to offer a good estimation of several thermomechanical parameters: temperatures, strains, strain-rates, stresses, tool wear, surface and subsurface integrity, burr formation, etc. To achieve this goal, advanced predictive and multiphysics models need to be developed. Cutting models can be based on different approaches: analytical, numerical, mechanistic, experimental, and hybrid modelling. Another important aspect of machining modelling is process stability and chatter. In industry, to avoid chatter vibration, the material removal rate is often reduced. Consequently, prediction and control of chatter require modeling of coupling between the thermomechanical process of chip formation and different sources of cutting instability as regenerative and frictional chatters. This Special Issue will cover recent advances in modeling of machining operations.

The topics include but are not limited to:

  • Multiphysics modelling of machining process: turning, milling, drilling, broaching, grinding, etc.
  • Thermomechanical process of chip formation
  • Tribology of machining process
  • Thermo-viscoplastic behavior
  • Tool wear: diffusion, abrasive, etc.
  • Surface and subsurface integrity
  • Burr formation
  • Cutting process stability
  • Optimization of the machining process: cutting conditions and tool geometry
  • Machining of traditional and new advanced materials (composite, ceramics, honeycomb, bulk metallic glasses, additive manufacture, etc.)
  • Micro-machining modelling
  • Machining-assisted process: cryogenic-assisted machining; ultrasonic vibration-assisted machining, laser-assisted machining, etc.

When assessing the effect of metal cutting processes on the resulting surface layer, the heat generated in the chip formation zone that is transferred into the workpiece is of major concern. Models have been developed to estimate temperature distributions in machining processes. However, most of them need information on the heat partition as input for the calculations. Based on analytical and numerical models, it is possible to determine the fraction of shear plane heat transferred into the workpiece for orthogonal cutting conditions. In the present work, these models were utilized to gain information on the significant influencing factors on heat partition, based on orthogonal cutting experiments, experimental results from the literature, and a purely model-based approach. It could be shown that the heat partition does not solely depend on the cutting velocity, the uncut chip thickness, and the thermal diffusivity—combined in the dimensionless thermal number—but the shear angle also has to be taken into account, as already proposed by some researchers. Furthermore, developed numerical models show that a more realistic representation of the process kinematics, e.g., regarding chip flow and temperature-dependent material properties, do not have a relevant impact on the heat partition. Nevertheless, the models still assume an idealized orthogonal cutting process and comparison to experimental-based findings on heat partition indicates a significant influence of the cutting edge radius and the friction on the flank face of the tool.
