The invention relates to a single-blade lateral milling method based on torsional
ultrasonic vibration. The single-blade lateral milling method is characterized in that an
ultrasound single-blade lateral milling device is driven by a
machine tool spindle to rotate, a workpiece is fed on a
machine tool
workbench, normal contact between a
tool bit and a
machining face is always maintained during
machining, the
turning radius of a
tool bit and workpiece contact point is smaller than the curvature
radius of the contact point on the workpiece, the vibration direction is the tangential direction ofrotation of a single-blade
milling cutter, and a single-blade lateral milling mode under torsional
ultrasonic vibration is realized. The single-blade lateral milling method has the advantages that themethod is novel, the structure is unique, the process is practical, and reliability is high; the
ultrasound single-blade lateral milling device is simplified in structure, downsized and convenient tomount; single-blade milling
impact is improved, the method is adapted to milling of narrow and deep structures, frequency variation of a sound and vibration
system is overcome, and heat
radiation ofthe sound and vibration
system is omitted; the problem of milling difficulty of high-
hardness high-precision complex
undercut hook faces and high-
hardness variable-
pitch spiral grooves is solved undercommon technological conditions, and the application prospect is abroad.
