Our 5-axis CNC machining services are considered for parts with features on several faces, compound angles, undercuts, or contoured surfaces. Drawing review considers tool access, datum relationships, workholding, material, tolerance callouts, and the requested inspection scope. We typically provide a quotation within two business days after complete drawings and project requirements are received; complex parts or missing information may take longer.
- Simultaneous 5-axis milling — undercuts, deep pockets, and compound angles in one clamping
- 3+2 indexed milling for angled but simple parts, where simultaneous motion buys nothing
- Drawing and manufacturability review based on the supplied project requirements
- Inspection methods and requested dimensional records agreed for the project
- Material traceability and certificates reviewed when requested and included in the agreed scope
- Surface finish requirements reviewed against the drawing and agreed finishing scope
Key Advantages
5 axis machining CNC and simultaneous 5-axis milling describe the same motion; what changes the bill is how many faces you dimension from and how many times the part has to be re-clamped. Every re-clamp adds a fixture, a datum shift, and an operator decision — so the gains below are measured in setups rather than spindle hours.
| Approach | Setups for a five-face part | Datum error risk | Where it fits | What drives the cost |
|---|
| 3-axis milling | Three to five re-clampings | Stacks with every re-clamp | Prismatic parts machined on one to three faces | Fixtures, handling, and labour |
| 3+2 indexed (same centers) | One or two | Low — the part stays clamped while the table indexes | Angled but simple faces, drilled and milled | Indexing time plus one fixture |
| 5-axis simultaneous | One | Lowest — datums never leave the machine | Undercuts, compound angles, contoured five-face geometry | Machine hourly rate |
Specifications
Machine configuration and setup are selected after reviewing the part model and drawing. Rather than publishing a general tolerance or size promise, we check the geometry, access, stock, workholding, and inspection requirements for the specific inquiry.
| Review item | What is checked |
|---|
| Geometry | Multi-face access, compound angles, undercuts, and contoured surfaces |
| Part envelope | Dimensions reviewed against available machine travel and workholding |
| Tolerances | Critical dimensions and datum relationships assessed from the drawing |
| Materials | Material grade, stock form, and availability confirmed for the project |
| Inspection | Measurement approach and requested records agreed within project scope |
For process comparisons, see our CNC machining services overview. Material suitability, stock availability, and any secondary finishing are confirmed against the drawing and project requirements.
Complex Part Geometry
Parts with features on several faces, angled passages, or contoured surfaces may benefit from a 5-axis setup when tool access and workholding permit. The drawing review determines whether simultaneous 5-axis machining, indexed machining, or another process is suitable.
For features with critical relationships across faces, the setup plan considers datum strategy and how dimensions will be inspected after machining.
