Special Issue Information

Dear Colleagues,

CAD/CAM/CAE technologies are finding more and more applications in today’s industry, i.e. in the automotive, aerospace and naval sectors. CAD-based applications have taken advantage of the application programming interface (API) available within the CAD/CAM/CAE systems and to move these research activities to a higher level. A number of difficult-to-perform manufacturing processes can be simulated using more methodologies available via advanced integrated CAD systems.

CAM technology has expanded beyond the creation of the appropriate CNC code needed for manufacturing unusual geometries with multi-axis machining centers. The trajectory optimization and time needed for manufacturing improvements have become extremely important issues.

CAE technologies deal with a number of simulations i.e. linear/nonlinear finite elements analyses, multi body dynamics and reverse engineering. The tools available become have more sophisticated and the engineers/researchers consider this challenge as an opportunity for more accurate simulations.

This Special Issue provides an opportunity for researchers to present recent advances and technologies in the aforementioned fields and indicate the future trends for CAD/CAM/CAE technologies.

Suitable topics for this Special Issue include, but are not limited to:

  • CAD based applications
  • CAD/CAM systems
  • Finite element simulations
  • Machining and manufacturing applications
  • CAM optimization methodologies
  • Design simulations
  • Computational design
  • Graphics algorithms
  • Geometric modeling
  • Reverse engineering
  • Prototyping
  • Robotics
  • Medical/biomedical applications
  • CMM applications
  • Automotive applications
  • Aerospace applications

The ball-burnishing process is a particular finishing treatment that can improve selected properties of different materials. In the present study, the ball-burnishing technique was used to investigate the effect of input parameters of processes on selected surface layer features like surface roughness and residual stresses of the 42CrMo4 steel surfaces. The burnishing process was conducted on Haas CNC Vertical Mill Center VF-3 using a tool with tungsten carbide tip. A further objective of our research was to improve tribological properties of the aforementioned steel by the ball-burnishing process. The results of the investigations showed that it was possible to reduce the root mean square height of the surface Sq from 0.522 μm to 0.051 μm and to increase wear resistance compared to ground samples.

This paper presents the results of a conducted topology management optimization study based on the finite element analysis on a two-stage spur gear reducer housing body and cover using the SOLIDWORKS Simulation module. The main goal of the study is to optimize the overall weight of the reducer by thinning specific areas of the casted gearbox housing elements according to the calculated minimal strain energy. The topology optimization algorithm that is used in current research gives an optimal structural shape of the housing elements of the reducer with the largest stiffness, considering the given amount of mass that will be removed from the initial design space. The complete sequence of steps for conducting the topology management optimization study is shown, taking into account the constraints arising from the construction features and the method of manufacturing the housing elements of the gear reducer. Conclusions on the use of the topology optimization results are given and potential directions for further development of the approach are also identified. Full article

This paper presents a numerical simulation chain covering induction hardening (IH), superimposed stroke peening (StrP) as mechanical post-treatment, and a final fatigue assessment considering local material properties. Focusing on a notched round specimen as representative for engineering components, firstly, the electro-magnetic-thermal simulation of the inductive heating is performed with the software Comsol®. Secondly, the thermo-metallurgical-mechanical analysis of the hardening process is conducted by means of a user-defined interface, utilizing the software Sysweld®. Thirdly, mechanical post-treatment is numerically simulated by Abaqus®. Finally, a strain-based approach considering the evaluated local material properties is applied, which reveals sound accordance to the fatigue tests results, exhibiting a minor conservative deviation of only up to two per cent, which validates the applicability of the presented numerical fatigue approach.
