CUTTING PLATE Russian patent published in 2012 - IPC B23C5/20 

FIELD: process engineering.

SUBSTANCE: cutting plate features polygonal prismatic shape with two opposed end surfaces and peripheral surface arranged there between. Note here that medium plate crossing cutting plate is located between end surfaces. Peripheral surface has multiple sides of polygon, each including side thrust surface and being connected with adjacent surface via rounded angle, each making vertex of polygon Note here that main cutting edge comprises three sections, on view side. Note also that rectangular first central section is inclined relative to medium plane. Raised second main section is conjugated with first main central section, while third main concaved section is conjugated with first main central section. Note here that auxiliary cutting edge comprises three sections, on view side. Note here rectangular first auxiliary section is inclined to medium plane while first main and auxiliary central sections are inclined in different directions. Raised second auxiliary section is conjugated with first auxiliary central section. It includes also concaved third auxiliary section conjugated with first auxiliary central section. Note here that main rear surface and appropriate lateral thrust surface make main rear angle varying from main first maximum values nearby top end of main edge to main second minimum value nearby bottom end of main edge. Auxiliary rear surface and appropriate rounded angle make auxiliary rear angle varying from auxiliary first maximum nearby top end of auxiliary edge to auxiliary second minimum nearby bottom end of auxiliary edge.

EFFECT: perfected tool.
