Safety on the manufacturing floor is always a critical consideration but for some reason, it is not an uncommon practice to market split axis machines with work envelopes larger than the footprint of the machine. This means that the moving pallet which is typically on the Y axis moves past the front (and rear) edge of the machine. Operators are then potentially in the path of the pallet as it moves back and forth.
In any reasonable machine design, no motion component should project beyond the footprint of the machine. A machine with a 500mm travel in the Y axis should have a base 1000mm from front to back at least. Of course the pallet can be design limited to not extend beyond the footprint, but this then shrinks the dispensable area in the Y and so purchasing a machine that doesn't have twice the footprint as the travel in the Y is not an effective use of funds!
In short, for any split axis design such as our CP16, CP2416, and our newly designed CP2420, the Y axis travel should be no more than half of the Y machine base footprint.
