Architecture Screen
Clarify the spindle architecture and proof path before CAD freeze or supplier commitment.
A bounded engineering engagement for a live custom gas-static spindle decision. It makes the operating envelope, assumptions, feasible options, governing risks and next required proof explicit before downstream cost is committed.
At a glance
The decision boundary before detailed engineering.
See the actual output
A bounded engineering decision, not a pile of calculations.
The public sample shows how one controlled case carries the operating state, support result, rotor consequence, evidence boundary and next action in one decision package.
A custom gas-static spindle decision is live.
The architecture or proof path is still uncertain and the next commitment would make change more expensive.
A bounded decision package.
Assumptions, feasible options, governing risks, sensitivities and the next required proof.
Non-confidential machine facts.
Machine/process context, speed, loads, envelope, gas state and the decision to be made.
Not a release or supplier mandate.
No production-release sign-off, certification, manufacturing quote or free numerical design work.
Architecture decision
Which spindle architecture is defensible enough to take forward — and what must be proved next?
The Screen stays upstream of detailed CAE. Its purpose is to reject weak options early, expose the governing operating state and define the smallest downstream proof that can still change the decision.
Process envelope
Loads, speed, accuracy, duty, gas supply and packaging.
Candidate synthesis
Direct calculation or inverse search across feasible support states.
Shaft-line context
Bearing placement, span, material, drive and tool interface.
Robustness
Worst operating corner, margin and rejected alternatives.
Rotor consequence
Mode-family separation, response and stability screen.
Next proof
What detailed CFD, FE, tolerancing or test must establish.
Architecture Screen output
A bounded architecture decision package, not a pile of plots.
Inputs, assumptions, candidate identity, numerical result, rejected states, evidence boundary and next action remain in one controlled handoff.
Selected bearing–shaft state
Geometry, restriction, clearance, supply state, shaft-line context and operating point.
Physical and rotor result
Capacity, stiffness, flow, margins, critical-speed family and response screen.
Risk and next proof
Weak states rejected, open questions named and the next engineering action stated explicitly.
Engagement boundary
Architecture Screen versus Architecture & Evidence Package.
The first engagement decides what is worth carrying forward. The deeper package begins only after an architecture has been screened and a higher-authority proof path is justified.
Architecture Screen
What should continue?- Project state
- Architecture still open.
- Main question
- Which option is defensible enough to take forward?
- Output
- Candidate, governing state, rotor consequence, rejected options and next proof.
- Authority
- Screening / architecture decision.
- Typical next step
- Supplier brief, targeted CAE/test, or deeper engineering package.
Architecture & Evidence Package
What must now be proved?- Project state
- Architecture already screened.
- Main question
- Which evidence must close the remaining decision risk?
- Output
- Controlled deeper analysis, evidence tasks, configuration basis and closure logic.
- Authority
- Scope-defined higher evidence; not automatic product release.
- Typical next step
- Validation, acceptance pathway or controlled design iteration.
Project Fit Check
Start with the decision, not a full specification.
Use the on-site form for high-level, non-confidential context. The first response establishes fit, missing inputs and the appropriate engineering scope before any proprietary files are exchanged.
Machine/process, decision, speed range, stage and work email. No CAD or proprietary files.
Breshev Engineering identifies the right engagement, data gaps and the evidence authority required next.
Expose missing decision inputs before they become supplier or CAE assumptions.
