A Vibration Damping Face Milling Cutter with Adaptive Instantaneous Variation of Tooth Pitch and Cutting Speed

Abstract

The invention discloses a damping face milling cutter with adaptive instantaneous change of a tooth pitch and a cutting speed. The damping face milling cutter comprises a cutter body, a flange, a plurality of indexable cutters, a spring and a mounting cutter handle; the cutter body comprises an outer cutter body, an inner cutter body and a bearing for connecting the outer cutter body and the innercutter body; the outer cutter body is located on the outer side of the cutter body, the inner cutter body is located on the inner side of the cutter body, and the indexable cutters are alternately connected with the inner cutter body and the outer cutter body; the flange is connected to the cutter body, and the spring is located between the flange and the cutter body; and the mounting cutter handle is connected with the cutter body. The damping face milling cutter with adaptive instantaneous change of the tooth pitch and the cutting speed can suppress the generation of self-induced vibrationduring cutting, and has a variable pitch cutting edge and a modulatable cutting speed.

Description

technical field [0001] The invention relates to the field of machining tools, in particular to a vibration-damping face milling cutter whose tooth pitch and cutting speed can be adaptively changed instantaneously. Background technique [0002] In machining, it is usually divided into various methods such as turning, milling, planing, grinding, and boring. In modern processing methods, milling is used more and more widely. Among them, face milling is a widely used and effective processing in modern engineering. Way. [0003] The inventor believes that self-excited vibration will be generated due to high cutting intensity or insufficient rigidity of the process system, thereby greatly reducing the precision and quality of the cutting surface, tool life, equipment durability and processing efficiency. The traditional methods of suppressing self-excited vibration include increasing the stiffness of the process system, changing the geometry of the tool and adjusting the cutting ...
