Analyse of Possibility of Form Tools Manufacturing Using Wire Cutting EDM

This paper presents an attempt to apply wire cutting EDM for manufacturing of form tool edges with cemented carbide. Was made the experiment of comparing edges made using wire cutting EDM techniques and conventional made in the grinding process. As a result of edge life research were found to be reduced of life wire cutting EDM edge by 50% compared to the conventional edge. Pointed to the possibility of creating a CAD-CAM system for form tools, the application of which will accelerate the production of these tools.
