In series production with CNC machines, tool-to-machine collisions drive up maintenance costs fast. 
In most cases, the cause isn't mechanical — it's operator input:

• An incorrect tool length offset entered after a tool change
• A faulty zero-point shift
• Restarting the program at the wrong line after an interruption

EWS COP (Collision Prevention) checks for exactly these kinds of errors automatically, in the background, and stops program execution the moment it flags an unauthorized change — before the machine moves an inch. All the data matching happens on a dedicated industrial computer, the EWS COP BOX.

What this means for your shop floor:

• Collision damage from operator error gets prevented, not just logged after the fact
• No extra sensors needed — monitoring runs entirely on existing control data
• Low overhead: quick setup, no ongoing data maintenance
• Full traceability, with every input and override logged

EWS COP is built for established series production (Siemens 840D SL, Sinumerik ONE, and FANUC controls). 
Please notice:
It doesn't cover manual setup mode (JOG) or the first run-in of new NC programs — that's where the EWS FLEX BOX comes in.
