Cutting composites is uniquely difficult when compared to cutting wood, metal, or other more traditional building materials. such as:

Composites do not typically transfer heat very well. Resin and cut fibers carry away relatively little heat, unlike metal chips, and overheating can melt resin or prematurely dull your tool. When resin melts, it can also clog your cutting tool or damage the finish of your part. In severe instances, there can be enough heat build-up near the edges of a laminate to sacrifice the structural integrity of a part.

Composites can delaminate when cut. Delamination varies from minor edge chipping (burrs, and fibers showing on poorly drilled holes/poorly trimmed edges) to major stress fractures due to poor bonding of resin to reinforcement.

With carbon fibre prepreg cutting machine, low-cost and can be used to make extremely small cuts.
