Edge preparation is defined by Cutting Tool Engineering as "Conditioning of the cutting edge, such as a honing or chamfering, to make it stronger and less susceptible to chipping." In this write up we will discuss edge preparation as it relates to cutting surfaces on carbide cutting tools. 

A well-sharpened edge is crucial for achieving consistency, prolonging tool life, and improving surface finish. In order to properly prepare edges for their intended tasks, precise measurement of a very small radius is necessary, often requiring the use of specialized measuring devices. 

Here is a deeper dive into the benefits of edge prep:

• Stronger cutting edge: Microscopic defects are common on new end mills from the manufacturing process. Edge prep helps remove these imperfections, creating a stronger and more chip-resistant edge. This reduces chipping and unexpected tool failures during machining.

• Improved tool life: By eliminating weak points and strengthening the edge, prep can significantly extend the lifespan of your end mill. This translates to fewer tool changes and overall cost savings.

• Better surface finish: A sharp, prepared edge allows for cleaner cuts with less burring or tearing on the workpiece. This can improve the final surface finish of your machined part.

• Reduced cutting forces: A properly prepped edge can reduce friction during cutting, leading to lower cutting forces. This translates to less stress on your machine and potentially allows for higher feed rates.

• Reduced chatter: Chatter is a vibration that can occur during machining, leading to poor surface finish and dimensional inaccuracy. Edge prep can help minimize chatter by creating a smoother cutting action.

With advancements in materials, manufacturers today demand exceptional performance from their cutting tools to stay competitive on a global scale. Edge preparation has played a significant role in enhancing cutting tools to achieve superior results. It is important to note that edge preparation for aluminum differs from that of steel, cast iron, composites, and other materials. At CGS Tool, we prioritize edge preparation as much as coatings, as they are fundamental to creating high-performance cutting tools that boost productivity and efficiency. Our team of experts is dedicated to ensuring that our cutting tools work tirelessly for your benefit.

Overall, taking the time to properly prepare your end mill edges can significantly improve your machining process by making it more efficient, cost-effective, and capable of producing higher quality parts.
