Description
Technical field
The invention belongs to technical fields of mechanical processing, and in particular to a kind of novel milling cutter for improving processing stability.
Background technique
Milling Process is a kind of advanced machinery processing life for being widely used in the fields such as Aeronautics and Astronautics, precision component manufacture
Production technology.With industry development and scientific and technological progress, the requirement to the shape, structure and surface quality of product is higher and higher.As
The Milling Process being most widely used in the field of machining becomes research focus, and stability of the milling cutter when processing operation is
Realize the basis of high performance Milling Process, and obtain the important way of the product of high quality therefore, how to improve milling cutter and add
It is apt qualitative.
Summary of the invention
The present invention provides a kind of novel milling cutter for improving processing stability to solve shortcoming in the prior art.
In order to solve the above technical problems, the present invention adopts the following technical scheme: the novel milling cutter of raising processing stability, packet
Knife handle and cutter hub that is coaxial and being integrally disposed upon knife handle front end are included, the withdrawing in circular ring shape is provided between knife handle and cutter hub
Slot, cutter hub outer surface have in axial direction been wholely set N helical milling sword, wherein N >=2, and N is integer, N helical milling
The blade for cutting a helical milling sword in sword is wave structure.
It between two blade tips of arbitrary neighborhood is the arc being recessed inwardly along the radial direction of cutter hub in wave structure
Groove structure.
It is that the V-type that is recessed inwardly along the radial direction of cutter hub is recessed between two blade tips of arbitrary neighborhood in wave structure
Slot structure.
Be between two blade tips of arbitrary neighborhood in wave structure along cutter hub radial direction be recessed inwardly it is trapezoidal
Groove structure, the upper bottom of trapezoidal groove structure are the bottom edge of trapezoidal groove structure, and the bottom length of trapezoidal groove structure is two
The distance between blade tip.
N=3。
By adopting the above technical scheme, when the blade of the helical milling sword of conventional milling cutters is the structure flushed, in milling workpiece
When, blade and the workpiece interaction of helical milling sword, constantly friction and extruding, with the progress of cutting, the energy of self-excited vibration
Amount constantly accumulation causes flutter, and milling stability is caused to be deteriorated.
The present invention is in milling operation, since the blade shape of a wherein helical milling sword passes through optimization design, design
For wave structure, this structure can inhibit the regeneration chatter generated in production and processing, improve milling operation processing stability,
Processing efficiency is improved, extends cutter life, obtains high-quality part.
Novel milling cutter of the invention is under high-revolving milling condition, by testing it can be proved that in identical machined parameters
Under, the milling cutter with a undulatory helical milling sword possesses better milling stability, more efficient processing after optimization
Efficiency.
The blade of a helical milling sword in the present invention is that wave structure uses three kinds of structure types, i.e. blade tip+arc
Connected in star structure；Blade tip+V-type groove structure；Blade tip+trapezoidal groove structure.These three structures are not only convenient for manufacturing, and meet
The requirement of milling operation stability.
