No matter what kind of processing is used, the blade of the plate shearing machine has three main angles: front angle, cut in angle and rear angle. Its functions are as follows: ① rake angle: it affects the cutting force, cutting edge strength and chip flow characteristics; ② Cutting angle: control the direction of cutting force, effectively reduce chip thickness and protect the weakest part of cutting edge; ③ Back angle: ensure that the tool will not rub with the workpiece when cutting.
Through the comprehensive optimization of these three angles of the tool, the cutting edge can be strengthened and the workpiece material can flow out freely from the cutting area, so as to reduce the cutting force and prolong the service life of the tool.
