CNC milling is suited to components whose function depends on accurately related faces, holes, pockets, and external profiles. The machining plan considers tool access, workholding, wall stiffness, and which datums must remain stable between setups.nnThree-axis, indexed, and simultaneous multi-axis paths are selected according to the part shape. Finishing and inspection requirements are included early so the part is ready for assembly rather than only for machining.
