PDA-DNC File Transfer

Deliver extreme shop-floor mobility by communicating with machine controls using standard ASCII, ISO, and EIA character sets directly from portable handheld Pocket PC hardware devices.

Custom Engineering Services

Integrate specialized SQL databases, PLC systems, industrial communication protocols, and custom user interfaces to capture comprehensive manufacturing process logs, sensor records, and machine audit trails.

Verified Program Integrity

Automated Traceability and Precision CNC Program Control

Our audit trail software eliminates guesswork on the manufacturing shop floor by tying every program transfer directly to an authenticated user, revision level, and exact timestamp. Machinists request files remotely from their machine tool controls, while the system verifies approvals, suppresses outdated code, and logs every scan event into your database to maintain rigorous manufacturing compliance and minimize scrapped parts.

Manufacturing Success Stories

See how leading industrial manufacturers safeguard machine operations with our proven DNC and process monitoring software.

"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

"Our daily activities in the Machine Shop have definitely become more manageable since installing Machine Link™. Machine Link™ has helped us to improve accuracy of records along with increased machine utilization. The bottom line is to say that we have overcome some big, big obstacles in our day to day..."

Steve Lisano

"Machine Link™ was easy to setup and we were able to quickly back-up all of our CNC program files from 46 different machine tools. We also, within minutes, established successful communications to a machine we had never spoken with before. It works great!"

Richard Recker

"Machine Link™ has significantly improved our productivity. We are now spending seconds doing what took us about thirty minutes before, since we had to manually enter each program. Plus, Machine Link™ is so easy to use that anybody in the shop can use it with minimal training."

Greg Scheldberg

"Machine Link™ really works well. We use its 'Search and Replace' capabilities virtually everyday. We can download a program from the control, make some quick changes, then send it right back."

Royce Burton

"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 the audit trail software track CNC program revisions?

The software continuously monitors file requests initiated directly from the machine tool control. When an operator requests a program, the system checks the file against the centralized engineering directory, ensuring only the latest approved revision is transferred. The system logs the scan event, recording the specific program name, revision level, requesting user, and exact timestamp into the database for comprehensive historical accountability.
