Difference between fillet end milling cutter and flat end milling cutter

Fillet end milling cutter and flat end milling cutter are two different types of end milling cutter, and the difference lies in the shape of the cutter head. The cutter head of the fillet end milling cutter has a circular chamfer, so it can reduce the contact area between the cutter and the workpiece, reduce the cutting force, reduce the machining temperature, and reduce the deformation and damage. The fillet end milling cutter is suitable for machining curved workpieces such as fillet and arc, which can improve the machining efficiency and quality. The cutter head of flat-end milling cutter has no circular chamfer, and the cutter head is flat, which has large contact area and large cutting force during machining and is prone to vibration and noise. Flat-end milling cutter is suitable for machining simple geometric shapes such as straight lines and planes, but it is not suitable for machining complex curved workpieces.
