Mastercam's Feature Based Machining (FBM) evaluates a part's features and automatically designs an effective machining strategy. With just a few clicks, FBM will detect solid machining features for the chosen FBM operation type, based on selection criteria; machine pockets using 2D roughing, rest mill and finish operations; automatically support closed, open, nested and through pockets and set the right toolpath options; optionally create a separate finish tool path for floors and walls; automatically identify when external machining is required and enable users to activate or deactivate it; automatically identify when facing is required; automatically create drilled, tapped, counterbore and countersink holes; automatically perform deep drilling, spot drilling, pre-drilling, tool selection and tool creation if needed. FBM also provides advanced controls to drill through, co-axis and split holes; select the appropriate tools for all operations, either from your preferred tools list or from libraries specified.

All tool paths are associative and editable after creation. This gives users a flexibility to make changes at any time and ensures that your parts will be cut exactly as you want them.
