Collision Protection Method

A method for the mitigation of damages in case of accidental collisions in a machine tool comprising a computer numerical control (CNC) and a plurality of axes, wherein the occurrence of collisions is monitored, the method comprising:

• identifying a first axis being an axis at which a collision is first detected;
• identifying a second axis being an axis parallel to said first axis;
• determining if both or one or none of the axes are resting, and
• if it is determined that said first and said second axis are resting, then either only said first axis is unlocked or both, said first and second axes are unlocked, and/or
• if it is determined that one of said first and second axis is resting, and that the other of said first and second axis is moving, then the moving axis is defined as the collider axis and is braked, and simultaneously the resting axis is unlocked or is made to step away or is held, and/or
• if it is determined that said first and said second axis are moving, then the first axis is defined as the collider axis and is braked, and simultaneously the second axis is braked or is unlocked or stepped away.
