Kennametal’s KOR 5 solid carbide end mill is designed for high-speed aluminum roughing in aerospace applications. The five-flute tool is said to allow for increased feed rates of 66% compared to three-flute tools. Miling Cutter
A tapered core, variable-pitch design and 35-degree helix reduce chatter and tool deflection, the company says. Through-tool coolant flushes chips away while reducing heat. The tool’s chip splitter pattern is designed to break up long chips to avoid recutting while also contributing to surface quality.
The KOR 5 enables machining with low radial engagement but high depth of cut, resulting in higher metal removal rates than traditional methods, according to Kennametal. Use with the company’s Safe-Lock shanks increases the tool’s predictability and prevents pull-out at higher feed rates.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
The forces involved in the milling process can be quantified, thus allowing mathematical tools to predict and control these forces. Formulas for calculating these forces accurately make it possible to optimize the quality of milling operations.
