Do CNC machine shops need CMMC?

CNC machine shops and precision machining contractors that receive DoD contracts or subcontracts involving CUI — particularly controlled technical information (CTI) in the form of engineering drawings, manufacturing specifications, or technical data packages — are subject to CMMC requirements. If your shop receives ITAR-controlled or EAR-controlled technical data to manufacture parts for the DoD supply chain, CMMC Level 2 likely applies.

What CUI do machine shops handle?

Machine shops in the defense supply chain commonly handle CUI including: technical data packages (TDPs) with controlled engineering drawings, manufacturing process specifications marked as CUI, material certifications tied to controlled contracts, and inspection and quality records for controlled parts. CUI received electronically (via email, file transfer, or portal) is often the primary driver of CMMC scope for machine shops.

How does CMMC affect CAD/CAM systems in a machine shop?

If your CAD or CAM systems receive, store, or process controlled technical drawings or CNC programs derived from CUI technical data, those systems fall within your CMMC assessment scope. This means the computers running CAD/CAM software, the file servers or cloud storage holding CUI drawings, and the network connecting them all require NIST 800-171 controls. VIS LLC's enclave design approach isolates these systems to minimize scope.

What is the minimum CMMC level for a machine shop with technical data?

A machine shop that receives Controlled Unclassified Information (CUI) — such as controlled technical drawings or specifications — typically requires CMMC Level 2 (110 NIST 800-171 controls). If the shop only receives Federal Contract Information (FCI) with no CUI markings, Level 1 (17 basic safeguarding practices) may be sufficient. The key determination is whether the technical data you receive is marked or designated as CUI.

CMMC Compliance Designed for Machine Shops and Precision Machining Contractors

Machine shops receive Technical Data Packages (TDPs) — drawings, specifications, and manufacturing instructions for defense components. These TDPs are CUI. VIS LLC helps machine shops scope their CUI environment, implement the NIST 800-171 controls required to protect TDPs, and prepare for C3PAO assessment without disrupting shop operations.

Most machine shops don't have an IT department — they have a shop manager and a few computers running CAD software. VIS LLC designs CMMC compliance programs that are right-sized for small and mid-size machine shops: minimal complexity, minimal disruption, maximum defensibility.

Key Features

TDP and technical drawing CUI scoping

We scope the CUI environment around the systems that receive, store, and process Technical Data Packages — minimizing your assessment footprint.

CUI-handling workstation hardening

We harden the workstations and systems that handle TDPs — implementing access controls, MFA, and endpoint protections required by NIST 800-171.

Minimal-footprint CUI enclave

We design a right-sized CUI enclave for machine shops — isolating TDP-handling systems from shop floor networks and general IT.

NIST 800-171 for small manufacturing IT

We implement NIST 800-171 controls scaled for small and mid-size machine shops — without requiring an IT department to maintain them.

C3PAO assessment preparation

We prepare your machine shop for formal C3PAO assessment — evidence packages, pre-assessment walkthrough, and mock assessor questioning.

Right-sized for small and mid-size shops

Every control implementation decision is made with your shop's size and operational realities in mind — no enterprise overhead, no unnecessary complexity.
