Process Route Fit Check
Machining is a subtractive process, so it is priced by the second. As soon as the shape of a part and the quantity required favour a forming process, the comparison stops being close. This check tells you which side of that line your part sits on — including when the answer sends the work away from us.
Your part
Which factors drove that verdict
Route comparison
| Route | Where it wins | What it costs you |
|---|---|---|
| High-volume CNC machining | Tolerance-carrying features, metals, traceable material, design that may still move | Priced by cycle second, so unit cost falls slowly once setup is amortised |
| Casting or forging | Thousands of pieces of a frozen metal design; near-net shape removes cutting time | Tooling investment and a redesign cycle; machining still needed on critical faces |
| Stamping | Sheet-like profiles at high counts | Die cost, and features that machine easily are not always easy to form |
| Injection moulding | Polymer parts at larger run sizes | Tool cost is the whole argument; machining is only the bridge while the tool is cut |
| Additive manufacturing | Complex or conformal geometry at low counts | Not a volume answer for steel and stainless part families |
If the check says machining, send the drawing and the release pattern. If it says otherwise, we would rather tell you now than two years into the programme. Talk to a Process Engineer About Your Volume →
This is a directional read from the factors that drive process choice, not a quotation. Any switch away from machining needs the redesign checked rather than assumed, because a feature that cuts easily may not form or fill.
