Profile and Tracer Milling. End mills are also commonly used for profile milling and tracer milling. In profile milling, the end mill follows a predefined shape, removing material from the workpiece to create the desired profile. This can include creating pockets, edges, or intricate curves on a workpiece's surface.
Also, when working with cobalt chrome, establishing proper cutting parameters is vital to prevent tool failure." Proper cooling at the cutting edge, reducing tool projections as much as possible, and using a very strong, rigid fixture setup on the machine will help deal with the challenges of milling cobalt chrome.
