Did you know that the global aerospace industry alone uses over 30% of the composites market, with this figure steadily rising in recent years? As manufacturers transition towards lighter materials to make their products more efficient and aerodynamic, the challenge of machining these complex materials intensifies. One critical issue these manufacturers face is excessive tool wear during CNC machining of composite materials. But what causes this wear, and how can manufacturers further mitigate this problem? In this blog, we will explore the intricacies of excessive tool wear when machining composites, providing insights and solutions to help manufacturers optimize their processes.
Understanding Composite Materials and their Unique Challenges
Composite materials, formed by combining two or more distinct materials, boast superior strength-to-weight ratios and excellent resistance to corrosion and temperature variations. However, these benefits come with challenges, particularly during the machining processes, due to their unique physical and chemical properties.
Structure and Composition
Common composites include carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP). While CFRP offers outstanding tensile strength, its abrasive nature can lead to significant tool wear. Similarly, GFRP provides excellent characteristics for specific applications but can become unstable during machining due to the glass fibers.
The Causes of Excessive Tool Wear
Understanding why excessive tool wear occurs during CNC machining of composite materials is crucial for addressing the problem. The key factors include:
