Feasibility and execution framework for micro-scale MIM gear classes used in dexterous robotic hand modules and compact actuator stacks.
Core bottleneck: Dexterous-hand programs require tiny, repeatable gear geometries that become expensive and slow when sustained only by micro-CNC routes.
| Decision Axis | CNC-First Route | Transition Route | Use Rule |
|---|---|---|---|
| Feature size and wall thickness | Preferred for ultra-thin or highly asymmetric prototypes | Micro-MIM candidate when minimum-section and repeatability gates are met | Reject transition if geometry fails agreed minimum feature stability criteria. |
| Backlash-sensitive mating interfaces | Machining-first for critical interface tuning | Transition only for non-critical repeated gear classes | Keep interface-critical elements under tighter verification control before route migration. |
| Volume and ECO frequency | Best for frequent geometry revisions and short pilot loops | Best for stable revisions with repeated lot demand | Delay route lock when engineering-change frequency remains high. |
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Micro-feature feasibility gate | Pass/fail by geometry, thickness, and tolerance stack | Micro-scale failures are usually geometry-bound, not solved by generic process claims. |
| Pilot acceptance repeatability | Inspection criteria locked before lot release | Unstable acceptance criteria create churn and block scale-up decisions. |
No. Route fit depends on geometry class, tolerance stack, and target volume; we screen these before route commitment.
Yes. Pilot-first validation with explicit fallback gates is part of the standard workflow.

Typical 5-9 working day CNC sample timing applies only after scope, material, inspection, partner route, and schedule are qualified. Pilot support is scoped separately after prototype assumptions are clear.
