Cutting Tool Measurement

Why Measurement of Tool Geometry is Important for Better Tool Life?

Introduction

Cutting tools are critical in producing high-quality parts and components in the manufacturing industry. End mills and drills are two of the most commonly used cutting tools, and their geometry is crucial in determining their performance and tool life. The geometry of these tools can significantly impact cutting force, chip formation, and tool wear, ultimately determining their tool life.

Dimensional Measurements

One of the most important aspects of cutting tool geometry is the measurement of angles and radii. Proper measurement of these angles and radii helps ensure that the tool has the desired cutting characteristics and can extend its life. The geometry of cutting tools does play a significant role in determining the tool’s life. Angles such as the cutting edge, relief, and rake angle can affect the cutting force, tool wear, and chip formation, ultimately impacting the tool’s life. A well-designed cutting tool with appropriate geometry can help extend the tool’s life and improve the cutting performance.

For example, the rake angle affects the cutting forces and chip formation, and a positive rake angle is generally preferred to reduce cutting forces and improve chip evacuation. The relief angle can also impact tool life by reducing cutting forces and controlling chip formation. The radius at the cutting edge affects the cutting performance and can impact the tool life by reducing tool wear and improving the finish of the machined surface.

The rake angle is essential in determining an end mill’s tool life. A small change in the rake angle can significantly impact the cutting performance and tool life. The rake angle affects the cutting forces, chip formation, and tool wear, affecting the tool life. A positive rake angle is generally preferred as it reduces cutting forces and can improve chip evacuation. However, the optimal rake angle depends on the machined material and cutting conditions, so careful consideration and selection of the rake angle are vital for maximizing tool life.

 

Accurate measurement of cutting tool geometry is vital for extending tool life, improving machining efficiency, and reducing production costs. A well-designed cutting tool with appropriate geometry can produce high-quality parts with less tool wear and lower cutting forces, reducing the frequency of tool changes and increasing productivity.

 

End-mill geometry, including the various angles and radii, significantly impacts the tool life. Proper geometry measurement helps ensure that the end mill has the desired cutting characteristics and a longer life, allowing for a higher value and premium pricing in the market. A more extended tool life can also improve machining efficiency and reduce production costs. Measuring the geometry of end mills is an essential step while manufacturing to produce high-quality tools.

Conclusion

In conclusion, the measurement of cutting tool geometry is a crucial step in manufacturing. Proper measurement of the angles and radii of end mills and drills helps ensure that the tool has the desired cutting characteristics and can extend its life. By improving the cutting performance and tool life, manufacturers can reduce production costs and increase their competitiveness in the market
