Building a Non-CUI Request Mechanism for CMMC

Maintain tight cybersecurity boundaries by establishing a secure, non-CUI request mechanism for manufacturing operations. Our automated DNC software enables shop-floor machinists to request and receive engineering-approved CNC programs directly at their machine tool controls without exposing regulated data environments. Streamline production workflows, reduce scrap, and deliver files efficiently while preventing scope expansion across your CNC machining network.

Our Program Delivery Services

Explore reliable DNC software and engineering services designed to deliver CNC programs securely across your machine shop floor.

Machine Link™ QUICK Serve

Shop-floor automation software that continuously monitors CNC machines for remote file requests and serves engineering-approved files directly back to machine controls, boosting productivity and eliminating manual PC interactions across the facility.

Machine Link™ QUICK Serve PLUS

Supports up to 20 simultaneous communication sessions from a single computer, allowing operators to remotely request files while engineering maintains full control over program changes and floor efficiency.

Machine Link™ QUICK Serve PRO

Remotely service up to 64 CNC machine tools simultaneously from a single workstation, eliminating shop-floor walking time and delivering approved files directly to controls with email or text message support.

Engineering Services

Custom engineering solutions for CNC communications, process monitoring, PLC hardware integration, and relational databases, backed by over 25 years of machining and systems integration experience.

Machine Link™

Reliable CNC and DNC file transfer software supporting standard RS-232 serial communications to easily edit, print, upload, and download programs directly to machine tools across your shop.

Machine Link™ BINARY

Specialized file transfer software equipped with binary file upload and download capabilities, designed for service technicians commissioning older controls and sending executive tapes in field environments.

Scope Isolation Architecture

Secure Program Delivery Without CMMC Scope Expansion

Delivering CNC programs to shop machines should never force your entire production floor into regulated CMMC scope. Our software allows machine operators to request and download engineering-approved programs at the machine tool control using simple keywords. This mechanism isolates file transfers, protects sensitive data boundaries, minimizes shop downtime, and eliminates unauthorized modifications across your manufacturing environment.

Customer Success Stories

See how manufacturing facilities and machine shops optimize CNC communications and file delivery efficiency.

"Machine Link™ is easy to use, was easy to setup, and worked the first time with no problems and I don't even know how to operate Windows. It is far superior to any other communication software I have ever tried. I love it!"

Ken Havard

"Machine Link™ is great! It's reliable and very easy to use. We manufacture high precision molds and use Machine Link™ to download very large files. We have never had a problem with it."

Frequently Asked Questions

How does a non-CUI request mechanism prevent CMMC scope expansion?

A non-CUI request mechanism allows machine operators to request CNC programs using simple, non-sensitive identifiers or keywords from their machine tool controls. By decoupling the shop-floor machine tools from direct access to Controlled Unclassified Information environments, the CNC equipment does not store or process regulated data. This architecture keeps shop-floor machines outside your primary CMMC boundary, significantly reducing compliance overhead and audit complexity.

How do machinists request CNC programs directly from the machine tool?

Can Machine Link QUICK Serve support multiple CNC machine tools simultaneously?

How are program edits at the machine returned to engineering?
