High precision machines cannot move without the permission of the manufacturer
a CNC mill Mori NV5000A
On the Practical Machinist forum turned enchanting discussion how to unlock a CNC mill, which refuses to function after moving to a new place.
The manufacturer equips the machine with a GPS-sensor and/or gyroscope. In case of moving of the machine is automatically locked until the unlock code.
The topic starter on Practical Machinist explains that their company has purchased eight CNC milling Mori/Ellison NV5000A, and soon transferred them to another plant. After that, the equipment is out of order. The manufacturer explained that this is a new requirement of American law and all future models of the CNC-milling of the highest class will be blocked when moving to a new location.
The user expresses indignation at this "salochki" machines at specific coordinates. He believes that after the purchase of the machine can do what you want with it.
Other colleagues on the forum confirmed that this same functionality with a GPS lock is present on other CNC milling high class Japanese production, including the mill Citizen. Say, changes in legislation adopted after one of the Japanese producers caught in the illegal export of precision equipment in Iran and North Korea, in violation of the embargo. Some even remembered scandal with the supply in the USSR machines Toshiba in the mid-80s, which allowed us to manufacture high-quality propellers for submarines, dramatically improving their acoustic profiles.
One way or another, but the history of milling is a very interesting example of how DRM-like schemes to penetrate into the real world.
