The following list describes the types of materials that are typically not good applications. Wood is often a poor application, due to its fibres’ absorption of water, which causes them to splay and become rough. Many fabrics do not cut well, as the fibres “squirm” out from under the cutting stream, rather than remain in place during the cutting process. However, the most common application that is incompatible with waterjet is pipe. Any material requiring the waterjet to cut through one layer, cross a void, then cut through another layer does not produce desirable results. The cutting stream does not remain cohesive after cutting through the upper layer, causing a poor edge quality on the next layer(s).
