Real-time collision prevention

The patented CrashGuard collision prevention system is a real-time software extension of the CNC control system. Based on an internal 3D-model of the machine, it prevents collisions between machine components both in automatic and manual operation.

Thanks to a 3D collision forecast, which takes into account the acceleration limits of the NC-axes, CrashGuard therefore rules out collisions between the various machine components.

The users are free to define their own minimum safety distances between the various collision pairings, e.g. top slide - bottom slide.

CrashGuard permits only movements which have been tested for collisions, so that the uncertainty factor “reaction time” does not apply.


CrashGuard at a glance

Software for real time collision prevention, integrated in the interpolator of the CNC system

For the machine operator

  • Effective protection against collisions in automatic and manual operation
  • Collision-free operation even after program interruptions and manual intervention
  • At any time, the CNC system is aware of current positions of axes and speeds, PLC signals are also taken into account
  • Current settings of the control such as zero offsets, coordinate transformation, etc. are taken into account
  • „Reaction time“ = 0 !!! (breaking distances are taken into account in the NC interpolator in advance, so that the result is not just near real time, but real time!)
  • All 3D geometry data (tools, clamping devices and workpieces) can be used for both CrashGuard and CrashGuard Studio. The two systems complement each other!
