Surface quality and production costs for sheet metal forming tools are the main factors with which a company can achieve competitiveness on the world trade market. With the use of newly developed materials such as gradient materials and new cutting techniques, companies are trying to achieve optimal tool and machine exploitation and in doing so gain an advantage over other companies. Cutting parameters have a major effect on the altogether productioncosts. For that reason, the majority of the researchers conduct off-line optimization of the cutting parameters. But the off-line optimizationis not suitable for newly developed work piece material such as graded materials. To machine such a material and to conduct monitoring of the whole process we developed and applied a new intelligent system for correctionof cutting parameters during milling of tool engravings into standard and gradient materials. The introduced system enables on-line optimization of cutting parameters and at the same time excludes the negative impact of human error into production. With the use of visual control and measurements of chip shape, tool wear and cutting forces, the system autonomously performs changes and corrections to both the cutting speed and feed rate. The research presents the introduction of the main problem, searchfor a suitable solution, assembling the system and experiments to verifythe usefulness of the system. A human interface is also developed for a faster reaction time to undesired events. In the conclusion of the research, the main results are presented and suggestions for further work and improvements are given.
