CMMC compliance for precision machining
CMMC Compliance for Precision Machining
Precision machining shops handle the tightest-tolerance work in the defense supply chain, often on export-controlled platforms. We get your Swiss, multi-axis, and EDM operations to CMMC Level 2 while protecting the CAD and metrology data that make your shop competitive.

Precision machining shops live and die on tolerance, repeatability, and intellectual property. The CAD models, inspection routines, and process notes that deliver sub-micron results are the most valuable digital assets in your company, and when the work is tied to a DoD contract, every one of those files is almost certainly CUI under NIST SP 800-171.
Swiss-type lathes, five-axis mills, wire and sinker EDMs, and micro-grinders each produce their own flavor of process data, from CAM setup sheets to probing cycles to compensation tables. That data rarely stays on a single machine; it moves between CAM seats, DNC servers, metrology rooms, and quality inspection systems. Every one of those hops is a point where a CMMC assessor will look for access control, audit logging, and encryption.
Export-controlled work compounds the risk. A foreign-person machinist, a USB drive carried home, or a cloud-based CAM license that stores files outside the US can all create an ITAR violation on top of a CMMC finding. Primes including Lockheed Martin, Raytheon, Pratt & Whitney, and General Dynamics are already enforcing CMMC flow-down on new precision machining subcontracts.
We build CMMC programs that respect how precision shops actually work. We scope the CUI enclave to protect the engineering, CAM, and metrology data without dragging every pallet pool and bar feeder into scope.
Controlled Unclassified Information We Protect in Precision Machining
Tight-Tolerance CAD & PMI Models
Fully dimensioned MBD models with PMI annotations; almost always CUI when received from a defense prime.
CAM Setup Sheets & Posts
Custom post-processor outputs, setup photographs, and work-offset records that reveal how the part is produced.
Probing & Inspection Programs
On-machine probing cycles, CMM routines, and vision-system macros tied to CUI drawings.
Process Capability Data (SPC)
Cpk and Ppk records, control charts, and gauge R&R data linked to defense part numbers.
Material Traceability Records
DFARS specialty metals compliance documentation, heat numbers, and lot histories.
First Article & PPAP Packages
AS9102 FAIRs, PPAPs, and CoCs that aggregate drawings, data, and process details into a single CUI artifact.

Precision Machining: CMMC questions
What CUI does my precision shop handle?
Your CAM files, CMM routines, setup sheets, PMI-annotated CAD, material certs, and FAIR packages are almost always CUI when tied to a DoD contract. The prime PO and DFARS 7012 flow-down are the definitive markers.
Does CMMC replace ITAR?
No. CMMC is a DoD cybersecurity framework; ITAR is State Department export control. Both apply simultaneously to most precision defense work.
Do I need to encrypt every CMM and CAM workstation?
Any endpoint that stores, processes, or transmits CUI needs FIPS-validated encryption at rest. For seats that never touch CUI we scope them out of the enclave.
