Process: 5-axis CNC milling for a complex illustrative component. Machine: multi-axis machining centre category selected after drawing review. Envelope: confirm stock, workholding, tool reach, and machine travel against the released model. Tolerances: identify datum scheme, critical features, and inspection frequency before quoting. Materials: aluminum, stainless, and engineering plastics shown as editable examples. Geometry: compound surfaces, angled bores, pockets, and sealing features drive the process plan. Finishes: record deburr, surface-finish, coating, and masking requirements. Inspection: define first article, in-process checks, final reporting, and CMM needs. Drawing requirements: provide revision-controlled 2D drawing, 3D model, quantity, material condition, finish specification, and acceptance criteria.
