An interesting video on using sliding wedges and rubber bands with a dowel grid for workholding:
Tiling is the term used to describe the process of working on a workpiece larger than your available work area. Usually it is used to cut pieces that are longer (Y axis) than your available area, since you are only limited in length by space available behind and in front of your machine.
The method involves using indexing pins in the workpiece and spoilboard to ensure that you can shift the workpiece an exact known amount. Then, within your CAD software, you define a restricted area to work on that matches each segment of the workpiece. You can use a toolpath to do a whole job, say define the outside contour cut of a workpiece, and then you duplicate that and limit it to a specific cutting area. Then you do the same thing from the second cutting area and so on. Stopping the machine and physically moving the workpiece in between jobs.
