CNC Manufacturing Documentation Reviewer

Job Title

CNC Manufacturing Documentation Reviewer / CNC Job Pack Expert

About the Role

We are looking for experienced CNC manufacturing professionals to review real-world CNC job packs submitted by manufacturing companies, CNC shops, machinists, or production teams.

The role involves checking whether submitted CNC documentation is authentic, technically relevant, complete, and suitable for use in an AI evaluation / manufacturing workflow research project.

The submitted materials may include engineering drawings, CAD/CAM files, G-code, setup sheets, tooling lists, process plans, inspection reports, material certificates, control plans, job cards, and other manufacturing documentation.

This is a reviewer role, not a design or programming role. The main responsibility is to evaluate the quality and completeness of submitted CNC job packs.

Responsibilities

The expert will be expected to:

1. Review submitted CNC job packs and confirm whether they appear to come from real CNC manufacturing work.
2. Check that files are not publicly available, AI-generated, generic, or artificially created.
3. Verify whether all files belong to the same part, job, drawing number, customer part number, or production workflow.
4. Evaluate technical completeness of each job pack.
5. Review engineering drawings, ballooned drawings, tolerances, material specifications, setup sheets, tool lists, process flow charts, control plans, and inspection documents.
6. Check whether CNC production artifacts such as G-code, CAM output, toolpath documents, or setup instructions are meaningful and connected to the job.
7. Identify missing or weak artifacts.
8. Flag confidential, personal, customer, or company-sensitive information that should be redacted.
9. Provide a short quality assessment and recommendation: accept, accept with minor issues, request more information, or reject.

Required Experience

Candidates should have practical experience with at least some of the following:

1. CNC milling and/or CNC turning
2. Reading engineering drawings and GD&T/tolerances
3. CNC setup sheets and machining instructions
4. CAD/CAM workflows
5. G-code / NC files
6. Tooling lists and cutting tools
7. Process routing / job cards / travelers
8. Inspection reports, QC checklists, CMM reports, or control plans
9. Material certificates / mill test reports
10. Real shop-floor manufacturing documentation

What You Will Review

A strong CNC job pack may include:

1. Customer request, RFQ, PO, or internal work order
2. Job card / route card / traveler
3. Engineering drawing or ballooned drawing
4. CAD files such as STEP, IGES, DXF, DWG, or native CAD
5. CAM files, toolpath exports, operation sheets, or setup sheets
6. G-code / NC files
7. Tooling list
8. CNC setup instructions
9. Process flow chart or control plan
10. Material specification or mill test certificate
11. Raw material inspection report
12. In-process inspection report
13. Final inspection report / CMM report
14. Photos of the part, setup, fixture, or machining process

Candidate Requirements

Applicants should:

1. Have direct experience in CNC manufacturing, CNC programming, machining, or manufacturing quality control.
2. Be comfortable reviewing technical drawings and manufacturing documents.
3. Understand what real CNC job documentation looks like.
4. Be able to identify incomplete, fake, public, or low-value files.
5. Be detail-oriented and able to provide clear written feedback in English.
6. Be available for part-time, project-based review work.
