hello some travels need to be monitorized for safety reasons, and here are 2 cases :
... something must be detected during that travel, thus colision is desired
... nothing must be detected, thus colision is not desired
in both cases, if all is fine, the machine must continue; solutions :
... colision is desired : basically, this is the feed skip, like when measuring a tool, using a renishaw, or spindle transfer with contact detection ( all functions that require G29 should suffice )
... colision is not desired : thus overload must be avoided, and here are 2 scenarios :
...... travel starts in air, thus there is a clearance until collision occurs, and for this case the basic vlmon, monitoring, is ok
...... travel starts in colision, thus there is contact when travel should begin, and here, the basic monitoring will fail, as it requires in imune time, and even without it, may trigger a too high overload and be to stressful for the axis, so an aproach based on diff error, which is type A alarm, can be used / kindly
