Materials such as carbon fibre and fibreglass are permeable and therefore extremely difficult to hold down. These types of materials require a clever approach, and a delicate cutting process.
Initially a sheet of film is applied over the top of the material which reacts well with the vacuum bed reducing the material to a few centimetres. The extra hold down ensures optimum cut quality with little or no material movement.
The material is then processed using the Pizza Wheel (Rotary Knife). The Pizza Wheel is available in two sizes, 2″ (50mm) or 4″ (100mm), and the choice of which to use is dependent on the material being cut. For example, in this video the 2″ blade is able to cut four sheets of 300g GRP.
All tooling used in this video can be purchased at CNCshop.
In order to use the Pizza Wheel knife the machine must have a tangential knife attached, learn more about this cutting option.
