The lack of constructional and technological knowledge and unsatisfactory marketing activities are the main reasons for refusing laser surface modification processes in production. The use of simulation methods and constructional rules cuts down the costs for designing and prediction of the technology drastically. The constructional knowledge and simulation methods of the laser hardening process have been existing since nearly 10 years. Computer programs using this knowledge can help especially small and middle sized companies to introduce laser hardening and to join new market segments. With the help of the presented simulation program users may predetermine technological parameters for laser hardening in complex cases within a few minutes.
