“By minimizing the width of cut you can elevate the surface footage on most alloys, with the exception of nickel-based alloys,” said Stusak. “You want to minimize the width of cut or arc of contact to beat the heat.” By minimizing the width of cut, not as much heat transfers into the tool because of the limited amount of cut time on the end mill. “The key to machining difficult-to-machine materials is the radial engagement,” he said. These strategies actively manage all four of the attributes in the CAM systems-including the radial width of cut, the arc of contact, chip thickness and the feed rate-for optimized performance,” he said.Ĭhip-splitting technology reduces the radial tool pressure encountered with long lengths of cut and helps break up the chips, producing more manageable chips for the operator or the chip pan or conveyor to remove, Stusak explained. “We have developed multi-flute tools, and specifically a seven-flute tool with chip splitting technology to allow very light widths of cut depending on the length of the flute on the end mill. “All four of those strategies are essentially the same,” said Stusak. Iscar has designed solid-carbide end mills specifically for milling strategies, including high-speed milling, high-efficiency milling, optimized roughing and proprietary CAM strategies like Mastercam’s Dynamic Milling. To capitalize on the latest machining strategies for milling difficult-to-machine materials, Iscar Metals Inc., Arlington, Texas, continues to add to its lines of multi-flute, solid-carbide end mills, according to Bryan Stusak, national product manager–milling. Removing metal is important, and doing it fast enough to make money is more important. ![]() Here’s how leading tooling manufacturers are helping customers put these tools to work in machining titanium, nickel-based alloys, superalloys, Inconel and stainless steel. Tools such as multi-flute, solid-carbide tools benefit from the latest advanced technologies in machine look-ahead, high-speed spindles, coatings and geometries. Powered by the latest CAM programs, these machining strategies are known variously as high-speed, high-efficiency, optimized roughing and also by proprietary brand names like Mastercam’s Dynamic Milling. How the latest end mill technology is being integrated into high-speed and high-efficiency milling processes to optimize metal removal rates Seco Tools has developed specific geometries, coatings, carbide substrates and edge preps for machining difficult-to-machine material applications.Īdvanced cutting tools can maximize metal removal rates (MRR) when machining even the most difficult-to-machine materials.
