The carbon fiber sheets are getting more and more popular in various industries such as aerospace, automobile, robot and sporting products. Their high-performance applications are best carried out using corrosion resistance, sleek appearance and high strength to-weight ratio, which is the main characteristic of a material. Nevertheless, carbon fiber sheets are not as easily machined as metals or plastics. The carbon fiber product has a special structure that necessitates specific methods to create precision and prevent damages.
Carbon Fiber is difficult to machine due to its properties.
Carbon fiber is a composite material that is produced by layers of woven material bonded with resin unlike metals. This stratified form makes it tough and at the same time susceptible to fraying, delamination or chipping in machining. The material is very abrasive, and hence wears down standard cutting tools very fast. In addition, carbon fiber dust is dangerous when it is inhaled hence appropriate safety precautions should be taken.
Carbon Fiber Sheet Machining Best Practices.
- Use the Right Tools
Carbide or diamond-coated tools are very strongly suggested to provide a clean and precise cut. These materials are able to handle the abrasive surface of carbon fiber and they can hold a sharpness longer than the traditional tools.
- Regulation CuttingSpeedand Feed Rate
The excess heat produced during the high-speed cutting can cause damage to the resin and result in the loss of the integrity of the sheet. Middle and slow cutting speed with steady feed rates are ideal in minimizing the fraying and prolonging the tool life.
- Attach the Workpiece to the Clamp.
During machining, any movement may cause an inaccurate cut or cracking. Precautionary steps to avoiding vibrations and damages entail clamping the sheet of carbon fiber so that the pressure is spread evenly.
- Maintain Dust management.
Carbon fiber sheets are machined and they result in fine dust that pollutes when breathed in. You should always work in a well-ventilated room and you should use protective mask and you should also have a vacuum system that is used to collect air particles.
