MACHINING OF LOW-STIFFNESS COMPLEX-PROFILE PART BLANKS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to machine building and can be used for surface plastic deformation of low-stiffness work pieces with curvilinear surfaces. Ball-like forming elements are arranged on bearing balls in acoustic concentrators opposite each other on both sides of workpiece. Lubricant-coolant is fed via axial channels made in acoustic concentrators. Ultrasound frequency or amplitude modulated oscillations are imparted to forming tool and lubricant-coolant.EFFECT: lower forming forces and resistance to plastic strain, lower contact temperature in processing area.1 dwg
