| Risk | Consequence | | :--- | :--- | | | CNC machines run on Windows; ransomware can destroy a $500k machine. | | Wrong Kinematics | A post for a DMU 50 (Swivel head) will crash on a Variaxis (Trunnion table). | | No Tool Center Point (TCP) | Will produce incorrect 5-axis moves, gouging the part or fixture. | | No Support | No one to fix it when your machine alarms out. |
