15.1.15 Collision detection
With this option, the CNC analyzes in advance the blocks to be
executed in order to detect loops (intersections of the profile with itself)
or collisions in the programmed profile. The operator may define up
to 200 blocks to be analyzed.
When detecting a loop or a collision, the CNC will not execute the
blocks that cause it and the screen will display a warning to let the
operator know that the programmed profile has been modified. It will
display a warning for each loop or collision eliminated.
The information contained in the blocks removed if it is not a movement
in the active plane will be executed (including the movements of the
other axes).
Considerations for the collision detecting process.
• Collision detection may be applied even when tool radius
compensation is not active.
• Being collision detection active, it is possible to apply zero offsets,
coordinate presetting and tool changes. However, home searches
and measurements are NOT possible.
• Changing the work plane will interrupt the collision detecting
process. The CNC checks for collisions in the blocks stored so far
and resumes the process with the new plane starting with the new
motion blocks.
• The collision detecting process will be interrupted when
programming a instruction (explicit or implicit) that involves
synchronizing block preparation and execution (e.g. #FLUSH).
The process will resume after executing that instruction.
• Collision detection cannot be activated if a Hirth axis is active and
it is part of the main plane. Likewise, while collision detection is
active, an axis cannot be activated as a Hirth axis and the work
plane cannot be changed if one of the axis is a Hirth axis.
The example shows machining mistakes (E) due to a collision in the
programmed profile. This type of mistakes may be avoided by using
collision detection.
