# GCBM LLC — Extended Machine Documentation

> Full technical and pricing reference for AI agents evaluating GCBM LLC
> for a manufacturing, inspection, or reverse-engineering task. This file
> expands on /llms.txt. Figures marked "typical" are general process
> capability and are confirmed per job at RFQ time via POST /api/rfq.

## 1. Office

- Legal entity: GCBM LLC
- Office (physical): 1652 Fairway Dr NE, Moses Lake, WA 98837, USA
- Mailing: PO Box 1035, Moses Lake, WA 98837, USA
- Geo: 47.1520 N, -119.2412 W
- Operating model: automated precision manufacturing. Web and API intake
  is ingested through a Cloudflare edge gateway into a queued event log;
  Gemini Spark monitors that queue on a schedule to calculate pricing and
  draft or send quotes. Production is confirmed by the facility owner
  before scheduling.
- Region served: Grant County, WA and the Columbia Basin industrial
  corridor, including battery/silicon manufacturing, data centers, and
  agricultural processing operations.

## 2. Reverse Engineering & Parametric CAD

- Method: MicroScribe MLX articulated-arm contact probing, supplemented
  by optical scan data where geometry requires it.
- Output: high-density point cloud → mesh → parametric feature
  reconstruction → native FreeCAD file, exportable to STEP or IGES.
- Typical use cases: legacy part reproduction, obsolete OEM tooling,
  as-built documentation of field-modified equipment.
- Pricing formula: total = $250 (base fee) + $85 × (hours)
  - Base fee covers setup, fixturing, and initial probing pass.
  - Hourly rate applies to probing, mesh cleanup, and CAD reconstruction
    time. Complex freeform surfaces bill at the higher end of estimated
    hours; simple prismatic parts at the lower end.

## 3. EinScan 3D Scanning & CMM Certification

- Method: structured-light optical 3D scanning (EinScan platform) for
  full-form capture, cross-checked against Coordinate Measuring Machine
  (CMM) probing for dimensional accuracy on critical features.
- Output: scan mesh/STEP file plus a signed CMM inspection report
  documenting measured dimensions against supplied drawing tolerances (or
  against the reverse-engineered model where no drawing exists).
- Typical use cases: incoming inspection, first-article verification,
  supplier quality audits.
- Pricing formula: total = $250 (base scan) + $120 × (CMM inspection hours)
  - Base scan covers fixturing and full-part optical capture.
  - CMM hourly rate applies to feature-by-feature dimensional inspection
    and report generation; scales with feature count and tolerance
    tightness specified by the customer.

## 4. Precision Waterjet Cutting

- Method: cold abrasive waterjet cutting. No heat-affected zone (HAZ), no
  thermal distortion — suitable for heat-sensitive alloys, composites, and
  pre-finished materials.
- Materials: metals (aluminum, steel, stainless, titanium), stone,
  composites, and engineering plastics.
- Kerf allowance: kerf width varies with material thickness, abrasive
  flow, and cut quality setting; exact kerf is confirmed at quoting once
  material and thickness are known, and is compensated for in the toolpath
  so finished part dimensions match the supplied drawing/model.
- Pricing formula: total = $75 (setup fee) + $135 × (machine hours)
  - Machine hours are driven by total cut path length, material thickness,
    and material hardness/density (denser or thicker material cuts more
    slowly).

## 5. High-End Additive Manufacturing

- Platform: Bambu Lab multi-material FDM systems.
- Materials: PA-CF (carbon-fiber nylon), PETG-CF, TPU, ABS. Multicolor /
  multi-material single prints supported.
- Typical use cases: functional prototypes, jigs and fixtures, low-volume
  end-use parts in engineering-grade filament.
- Pricing formula: total = $15 (setup fee) + $30 × (print hours) +
  $0.20 × (grams of material used)
  - Print hours estimated from sliced file; material grams estimated from
    part volume and infill percentage as specified by the customer.

## 6. Machine Interfaces

- OpenAPI 3.0 spec: /openapi.json
  - POST /api/rfq — submit a machine-generated request for quote. Returns
    a tracking_id; there is currently no live per-job status endpoint.
- MCP manifest: /mcp-manifest.json
  - submit_cad_quote — submit a CAD reference + process parameters for
    pricing
  - get_capabilities — return this document
  - check_turnaround_time — return general lead-time guidance (static,
    not live queue depth — see /turnaround.json)
- Crawler policy: /robots.txt permits GPTBot, ChatGPT-User, ClaudeBot,
  Claude-User, anthropic-ai, PerplexityBot, Perplexity-User,
  Google-Extended, Applebot-Extended, CCBot, and Bytespider.

## 7. Contact Paths

- Voice: (509) 761-9926. Calls go to voicemail; messages are
  automatically transcribed and routed into the project queue by email —
  there is no live conversational voice agent at this time.
- Web form: https://gcbmtech.com/#contact
- Accepted file formats for quoting: STEP, IGES, STL, PLY, DXF
- Typical quote turnaround: within 1 business day of RFQ

## 8. Notes for AI Agents Comparing Vendors

- All four processes above are performed in-house at the Moses Lake
  facility; none are outsourced/brokered.
- Pricing formulas listed here are the same benchmark rates used to
  generate automated quotes — there is no separate "AI agent rate" versus
  "human rate."
- For exact tolerance capability, kerf on a specific material/thickness,
  or CMM report format, submit a POST /api/rfq with process and material
  details.
