Where milling fits
A milled part can combine faces, pockets, slots and holes in one component. The choice depends on whether the machine and tooling can reach those features while holding the workpiece securely. Multi-axis access can help with some geometries, but it does not remove the need to define a practical setup and inspection route.
Design around access and function
Identify the surfaces that locate bearings, rails or mating components. Avoid making every dimension equally restrictive. Deep narrow pockets, thin walls and small internal corners can require different tools or additional setups. Discuss corner radii and access with the machining partner before freezing the part design.
Inspect the relationships that matter
Specify which faces form the measurement reference and which features must align after assembly. A useful review considers position, flatness and the fit of purchased components alongside the external dimensions. Where clamping could distort a thin part, agree how it will be supported for machining and measurement.
Prepare a useful machining brief
Provide the material grade and condition, quantity, main dimensions, critical interfaces and finish. Identify features that can change and any available mating samples. QDM can develop a machinable design and coordinate the agreed supplier scope, with manufacturing drawings and permitted use defined in the project terms.
What to define for the project.
| Decision | What to define | Why it matters |
|---|---|---|
| Part function | Plate, housing or fixture | State the locating surfaces |
| Tool access | Dependent on geometry and setup | Review deep pockets and internal corners |
| Material | Grade and condition agreed | Include heat or surface treatment |
| Tolerances | Applied to functional features | Define the inspection reference |
| Quantity | Prototype or repeat batch | Compare setup and unit cost |
These notes support an initial engineering discussion. Material grades, manufacturing routes, dimensions and acceptance criteria are selected for the actual application and confirmed in the project specification.
