CATEGORIESCNC PROCESS GUIDE / DRAWING-BASED MANUFACTURING
Choose the Right CNC Process for Your Part
Milling, turning, hole-making, multi-axis machining, grinding and EDM address different features and manufacturing requirements. A finished component may use several of these operations.
Start with the part geometry, material, tolerances and surface requirements. Use this guide to explore the operations and prepare your drawing for review.

CNC milling uses rotating cutters to remove material from a secured workpiece. Controlled movements create flat, pocketed and complex non-cylindrical geometry.
CNC turning rotates the workpiece while a cutting tool removes material. It is commonly used for rotational and cylindrical part geometry.
Hole diameter, depth, tolerance, finish and thread requirements help determine the necessary tools and operations.
Additional axes help the tool reach more sides and approach directions. The appropriate configuration depends on geometry, tool access and the required setups.
Common for standard milling features and multi-face components using conventional setups.
Useful when rotational positioning or machining around a component is required.
Supports suitable complex geometry and features requiring different tool-access directions.
Grinding uses an abrasive wheel to remove small amounts of material. It is often applied after machining to refine dimensions, flatness, roundness or surface finish.
Typical uses: shafts, tooling components, hardened parts and precision finishing surfaces.
EDM removes electrically conductive material through controlled electrical discharges.
Typical uses: narrow slots, intricate internal features, hard conductive materials and tooling components.
Common methods include wire EDM and sinker EDM.
| Part Feature or Requirement | Process to Review |
|---|---|
| Flat surfaces, pockets, slots and complex profiles | CNC Milling |
| Cylindrical or rotational geometry | CNC Turning |
| Round holes, controlled bores and internal threads | Drilling / Boring / Reaming / Tapping |
| Complex multi-face geometry and tool-access directions | Multi-Axis CNC Machining |
| Refined dimensions, flatness, roundness or surface finish | Grinding |
| Difficult features in electrically conductive material | Electrical Discharge Machining |
EXAMPLE / A SHAFT WITH FLATS AND CROSS HOLES
The main shape and individual features can be produced through a sequence of operations.
Produce the required diameters, shoulders and other rotational features.
Add flats, cross holes or other features defined on the drawing.
Add grinding or surface finishing where specified, then inspect the critical dimensions.
Project support can include deburring, finishing, machining after fabrication and assembly when specified. Inspection follows the agreed drawings and project requirements.
