The paper deals with the issue of the machining process optimization by using algorithms that proposed for the creation of NC strategies in CAD / CAM systems. The possibilities to create NC strategy in CAD / CAM systems using Feature Based Machining has been analyzed using Edgecam's Strategy Manager Module, Mastercam's FBM Drill, and Machining Knowledge Editor in the Siemens NX10. For experimental use has been suggested Strategy Manager Module of CAD/CAM system Edgecam. Based on the definition of NC strategy creation in this system, algorithms for creating of new NC strategies have been proposed, and database application for this NC strategies have been created. The use of created NC strategies will eliminate the repetitive steps in creating the machining process and will bring shortening the time when creating the NC program.
