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 toolpath for floors and walls; identify when external machining is required and enable users to activate or deactivate it; identify when facing is required; create drilled, tapped, counterbore, and countersink
holes; perform deep drilling, spot drilling, pre-drilling, tool selection, and tool creation if needed; provide advanced controls to drill blind, through, co-axial, and split holes; and select the appropriate tools for all operations.
