- Platform integration: The new capability will be delivered through MAIT’s existing PTC Creo and Siemens NX environments.
- Early‑stage insight: Engineers can now run tolerance and variation simulations during concept design, cutting downstream re‑work.
- Lifecycle alignment: The partnership bridges engineering and manufacturing, helping firms hit quality, cost and time‑to‑market targets.
Introduction
MAIT Group, a global engineering services firm, has announced a partnership with Sigmetrix, a specialist in mechanical variation analysis. The collaboration expands MAIT’s digital‑product development portfolio by adding a dedicated Mechanical Variation Management (MVM) service line aimed at improving product quality, controlling costs, and streamlining development schedules.
Why Mechanical Variation Matters
The challenge
During machining, stamping, and assembly, parts inevitably deviate from their nominal dimensions. Even a 0.02 mm shift can cascade into assembly mis‑fit, increased scrap, or costly redesigns. Traditional tolerance stacks often rely on worst‑case assumptions, inflating safety margins and part costs.
The Sigmetrix solution
Sigmetrix’s MVM platform uses statistical tolerance analysis, Monte‑Carlo simulation, and model‑based definition (MBD) to predict how real‑world variation impacts assembly performance. The company’s toolkit has been refined over 25+ years across aerospace, automotive, and heavy‑equipment sectors.
| Feature | Traditional Stack‑up | Sigmetrix MVM (via MAIT) |
|---|---|---|
| Analysis method | Deterministic worst‑case | Probabilistic Monte‑Carlo & RSS |
| Result type | Single “max‑min” envelope | Probability distribution (e.g., 95 % confidence) |
| Design iteration impact | 2–3 extra cycles on average | Up to 30 % fewer iterations (per internal case studies) |
| Cost impact | 5–10 % higher part cost due to over‑tolerancing | 3–6 % cost reduction by optimized tolerances |
| Tool integration | Stand‑alone spreadsheets | Embedded in PTC Creo & Siemens NX |
Integration into MAIT’s Solution Stack
Platform coverage
MAIT will embed Sigmetrix’s algorithms directly into its PTC Creo and Siemens NX solution portfolios. Engineers working in these environments can launch variation analyses from the same CAD session, eliminating data‑transfer steps and reducing the risk of version mismatch.
Workflow benefits
| Stage | Current workflow | Post‑integration workflow |
|---|---|---|
| Concept design | Manual tolerance speculation | Real‑time statistical tolerance preview |
| Design validation | Physical prototype or static FEA | Virtual “variation‑aware” simulation |
| Manufacturing hand‑off | Separate GD&T review | Unified MBD‑driven documentation |
| Production monitoring | Post‑mortem quality audits | Early‑stage predictive quality metrics |
Business Impact
- Reduced time‑to‑market: Early detection of tolerance bottlenecks can shave 2–4 weeks off typical product development cycles.
- Cost savings: Optimized tolerances have shown 3–6 % part‑cost reductions in pilot projects.
- Quality uplift: Probabilistic analysis improves first‑pass yield by an estimated 5–8 %.
- Design iteration cut: Companies report up to 30 % fewer design revisions when using integrated MVM tools.
How MAIT Will Deliver the Service
- Consulting kickoff: MAIT engineers assess the client’s current GD&T practices and MBD readiness.
- Tool deployment: Sigmetrix’s MVM modules are installed as plugins within the client’s PTC or Siemens environment.
- Training & enablement: Hands‑on workshops teach design teams to run Monte‑Carlo simulations and interpret probability‑based results.
- Ongoing support: MAIT provides continuous analytics, model updates, and cost‑impact reporting throughout the product lifecycle.
Bottom Line
The MAIT‑Sigmetrix partnership injects a mature, statistically‑driven variation management capability into MAIT’s already robust PTC and Siemens platforms. By moving tolerance analysis upstream and embedding it within the CAD environment, manufacturers can expect faster development, lower part costs, and higher first‑pass quality. For organizations pursuing Model‑Based Definition or Model‑Based Enterprise initiatives, the combined offering delivers a clear, data‑backed path to tighter engineering‑manufacturing alignment.
