A. Description :
Precision cutting tools are made from various materials, including carbide, high-speed steel and ceramics. Each material has unique properties that make it well-suited for different cutting applications. For example, carbide is tough and durable, making it ideal for cutting through rigid materials like steel and titanium. On the other hand, high-speed steel can withstand high temperatures, making it perfect for carving at high speeds.
The science of precision cutting tools is concerned with understanding the fundamental principles of cutting materials and optimising the cutting process for different applications. Several key concepts are essential to know when it comes to cutting, including:
Cutting speed: This refers to the rate at which the cutting tool moves through the material. Faster speeds can lead to higher productivity but also generate more heat and wear on the cutting tool — which you can easily replace, provided you know how to change the parts of a cutting tool.
Feed rate: This refers to the rate at which the cutting tool moves into the material. A higher feed rate can lead to faster cutting and increase the risk of tool breakage or material deformation.
Cutting edge geometry: The cutting edge's shape and angle can significantly impact the process. For example, a sharp edge will slice more quickly than a dull edge but will also be more prone to wear. Precision cutting tools are not only exact, but they are also fantastic. This fineness allows for the creation of intricate and complex parts that would be impossible to produce using traditional cutting methods. Several key technologies help achieve this level of class — they include:
Superabrasive cutting tools: These are made from superhard materials such as diamond or cubic boron nitride. They can cut at much higher speeds and with greater precision than traditional cutting tools made from carbide.
Coated cutting tools: Many precision cutting tools are coated with a thin layer of complex, wear-resistant material such as titanium nitride or titanium carbonitride. This can extend the tool's life and improve its performance.
Nano-scale cutting tools: Advancements in nanotechnology have allowed the manufacturing of cutting tools on a nano-scale, which have exceptional strength and wear resistance. They are also known as micro cutting tools, since they are minimal in size
