Hello,
I work with a CNC turret punch and we call this 'repositioning'. The older turrets commonly have 72" X travel and 48" to 50" Y travel, but the machine has the capability to automatically reposition a sheet(the machine moves the sheet under the turret and there are 2 hydraulic hold downs that grab the sheet and hold it while the pneumatic clamps unclamp and move to the repositioned clamp zone and reclamp the sheet, and the punching program will resume from there. At the end of the program the sheet is usually repositioned to the beginning position so it will return to the home position without overhanging the machine.
Yes, on a machine not equipped with an auto-repositioning feature it can be a pain but is one way to accomplish the task with the smaller axis travels. I have done some 3D machining on my small SX3 CNC mill that needed several repositions in the X and Y axis and was quite a task but very rewarding to have accomplished it.
Regards,
