Factors to Consider When Choosing a CNC Cutting Tool
Cutting tools are vital in defining a machining strategy. Choosing the right cutting tools and parameters ensures efficient machining, maintains geometrical tolerances, and improves productivity. Here are the top 12 factors you should consider before selecting your cutting tool for CNC machining:
1. Material Type
First, the material of the workpiece plays a pivotal role. Different materials, such as metals, plastics, and composites, have varying characteristics that require specific cutting tools. For instance, harder materials like stainless steel or titanium necessitate tools made of exceptionally hard materials like carbide or diamond. This will help them withstand the machining process without significant wear. Engineers often start with proven standardized tools to minimize risk, inventory, and costs.
2. Cutting Tool Material
Equally important is the cutting tool material itself. The same cutting tool can be made from various materials, each offering different levels of durability and cost. The tool’s material determines its durability, performance, and suitability for different machining tasks. High-speed steel (HSS), carbide, ceramics, and polycrystalline diamond (PCD) are common materials used for cutting tools, each offering distinct advantages.
Cutting tools made from different materials
Carbide tools, for example, are known for their hardness and heat resistance, making them suitable for high-speed applications. Solid carbide tools are reliable, but PCD-tipped tools are even more durable. PCD, or polycrystalline diamond, is the hardest modern cutting tool, made by sintering diamond particles with a metallic binder. A PCD-tipped drilling tool lasts about four times longer than a solid carbide tool and can run up to 25% faster. This performance offsets the cost difference and results in production savings.
Unlike solid carbide tools that lose diameter after a few regrinds, PCD tools can be retooled multiple times. CNC machine shops use cutting monitors, tool life counts, and experienced operators to predict and prevent tool failure, ensuring proper cutting. An economical alternative to solid carbide is a steel tool body with brazed carbide inserts, which can reduce costs by up to 75%. Other options include high-speed steel tools and carbide-tipped tools, which smaller CNC machine shops prefer for cost-effectiveness. HSS tools are more affordable and versatile but may wear out faster under extreme conditions.
3. Type of CNC Machining Operation
Different operations, such as drilling, milling, turning, or threading, require specific tool designs tailored to their unique requirements. Each operation demands a particular tool shape, size, and material to achieve the best results, making it essential to match the tool to the task at hand accurately.
4. Cutting Tool Properties
The tool properties may include tool coatings and tool geometry. Tool coatings, such as Titanium Nitride (TiN), Titanium Aluminum Nitride (TiAlN), and Diamond-like Carbon (DLC), enhance tool life and performance by reducing friction, increasing hardness, and improving heat resistance. These coatings can significantly extend the lifespan of a cutting tool and improve its efficiency. Tool geometry, on the other hand, involves the shape and design of the cutting tool, including rake angle, relief angle, and helix angle. These geometric factors influence cutting efficiency, chip removal, and surface finish, making them essential for achieving the desired machining results.
Tool holding and stability are also critical for ensuring precision and avoiding tool breakage. Proper tool-holding systems, such as collets, chucks, and holders, provide the stability needed to maintain accuracy and prevent vibrations. Inadequate tool holding can lead to inaccuracies, reduced surface quality, and increased tool wear, making investing in reliable holding solutions essential.
5. Tool Capacity
The CNC machine’s rigidity, power, spindle speed, and feed rates should align with the cutting tool’s requirements. Using a tool incompatible with the machine’s capabilities can lead to suboptimal machining or even tool failure. This alignment ensures that the tool can perform at its best, maintaining accuracy and efficiency throughout the machining process.
Multiple-feature tools can save significant costs and labor in CNC machining. A single tool that performs several tasks, such as three or four, increases cycle time and reduces tool change time. For example, a well-designed insertable combo tool can drill and chamfer in three different ways, completing the job in one pass instead of six using just one tool.
6. Cutting Parameters
Cutting parameters, such as cutting speed, feed rate, and depth of cut, must be carefully considered. These parameters directly impact tool wear, heat generation, and the quality of the finished part. For instance, higher cutting speeds may increase productivity but lead to faster tool wear, necessitating a balance between speed and tool longevity. Properly adjusting these parameters can optimize the machining process, ensuring a high-quality outcome while extending the tool’s life.

7. Production Volume
The scale of production, whether it is low, medium, or high volume, significantly impacts tool selection and overall machining strategy. For low-volume production, the emphasis might be on flexibility and versatility. In such cases, general-purpose tools that can handle a variety of materials and operations efficiently are preferred. These tools may not need the highest level of durability or the most advanced coatings since they are not subjected to extensive wear and tear.
In medium-volume production, the demand for higher consistency and efficiency increases. Cutting tools must offer a balance between longevity and performance to handle the moderate workload without frequent replacements. Here, tools with specific coatings and geometries tailored to the workpiece material and type of operation can optimize production efficiency and maintain quality standards.
High-volume production presents unique challenges and requires the most robust and durable cutting tools. The tools must withstand continuous use and high-stress conditions while maintaining precision and quality over long production runs. Advanced cutting tool materials, such as carbide or PCD, and specialized coatings are often necessary to ensure the tools’ longevity and performance. High-volume production also benefits from cutting tools specifically designed for automated machining processes. This reduces the need for frequent tool changes and minimizes production interruptions.
8. Tool Life and Cost
Tool life and cost are interrelated factors that must be weighed carefully. While high-performance tools may come with a higher upfront cost, they often provide better longevity and overall cost-effectiveness by reducing downtime and replacement frequency. Investing in quality tools can lead to significant savings in the long run by minimizing interruptions and maintaining consistent performance.
9. Surface Finishing Requirements
The desired surface finish can significantly influence tool selection. Tools with finer geometries and advanced coatings can achieve smoother finishes, which is critical for parts requiring high precision and aesthetics. The right tool can ensure that the finished product meets the stringent surface quality standards demanded in many industries.
10. Chip Control
Effective chip control is essential for maintaining machining efficiency and preventing tool damage. Tool designs that promote efficient chip evacuation reduce the risk of re-cutting chips and tool clogging, which can otherwise compromise the machining process and lead to tool breakage. Proper chip control ensures a smooth operation, enhancing both tool life and workpiece quality.
11. Coolant and Lubrication
The use of appropriate coolants and lubricants can significantly impact tool life and cutting performance. CNC Coolants and lubricants reduce heat and friction, enhancing the tool’s efficiency and longevity. Ensuring compatibility with both the tool and the workpiece material is crucial for achieving the best results and maintaining a smooth machining process.
12. Part Complexity
The complexity of the part being machined should be considered. Intricate designs with tight tolerances and complex geometries may require specialized cutting tools that can achieve the necessary precision and detail. These tools must be capable of handling the specific demands of complex parts without compromising quality.
