CNC machines can often be seen sporting a piece of paper covering the control screen. This is an attempt to alert shop workers to “stay away” while a maintenance function is being performed. The problem is, paper is not a very effective means of communicating why others should not touch the control, and under whose authority. It can easily be ignored, “overridden” (torn off), and sometimes the paper simply falls off during the course of a busy shop day. When operations such as CNC machine testing, maintenance procedures and backups are disrupted, this can be very disruptive to your productivity.
A High-Tech Piece of Paper
The Screen Blocker app was developed as a replacement for what service technicians and others have been using for decades. Screen Blocker is essentially a high-tech piece of paper. It’s better than paper though, because its contents are more highly customizable and can be saved and restored. Screen Blocker does more than merely cover the screen; it prevents people from accessing the control screen by using password protection.
Get Started With the Screen Blocker App
The Screen Blocker app is available as a free download from the Okuma App Store. Microsoft .NET Framework 4.0 is required, which means it’s capable of running on THINC®-OSP P100 to P300 series controls. If the CNC machine control is running Windows® XP, a prerequisite to installing .NET 4 is that the Windows version has Service Pack 3 (SP3). For complete details on using the Screen Blocker app, please review the User Manual.
To simplify installation of any machine tool app from the App Store, we recommend first installing the SCOUT app, which quickly identifies if your CNC machine is compatible. If you need help getting started with apps for your CNC machines, please contact your local distributor or Okuma America.
