Abstract: A design is formed in a carpet secured to a table with a carriage controlled and moved over the table by a computer. A carver is mounted to the carriage and is computer-controlled to carve a design into the secured carpet. Also, a separator is mounted to the carriage and is computer-controlled to separate the carved carpet into a plurality of pieces. The secured carpet has a grain extending in a first particular direction, and carving in a second particular direction produces an actual result offset from an intended result by a quantified offset. The first direction and second directions are determined and a relationship therebetween is calculated. An offset associated with such relationship is then determined, and the determined offset is employed to position a carver during carving in the second direction. Thus, the employed offset produces an actual result that aligns with the intended result.
