1. Analysis of the Service Life of Cold Forming Tools

   Analysis of the forming process and its parameters (forming force and stress, deformation and strain, temperature, state of stress etc.) is very usefull because these parameters influences not only quality of the produced parts but also the service life of forming tools. The main aim of the works will be focused on experimental verification and forming tool observation in the real forming process. By using of analysis will be determine wear mechanism of forming tools and its influence not only on forming tools service life, but also on its possibility to influence the quality of produced parts. The results of the experimental works will be verified also by computer simulating.

2. Crystallization control of heavy castings

   Manufacture of heavy castings represents a specific field of foundry technology connected particularly with solidification kinetics. The work is aimed at the filed of crystallization control and intensification of cooling and solidification rate with the aim of suppressing the formation of defects related with a long time of heavy casting solidification.

4. Development of new methods and tools in evaluating the quality of die-cast Al alloys

   Preparing complex quality tools based on analytical relations between solidification parameters and microstructure characteristics subsequent to casting (quality index). Mechanical parameters can be predicted via simulation (MAGMA + SIMTEC) and optimized via controlling the casting process; criterial functions can thus be created. Assessment of critical places of stress relations experimentally and by way of simulation. Optimum method of heat treatment with the aim of reducing residual stress. Evaluation of competitiveness by means of quality function deployment and using statistical process control.

6. Optimization of Deep Drawing Technological Process

   The work targets firstly on the measuring of parameters which are used as enter data when modeling technological process of deep drawing and secondly on determination of reliability of their valuation. The next part of the work is devoted to understanding how the changes of the enter parameters influence the results of the simulation. The results of simulations will be compared with experimental values and as the final result will be a practical recommendations for using of studied enter parameters in computer simulation of deep drawing technological process together with the evaluation of values reliability.
