METHOD OF POCKETING TOOL MANUFACTURING WITHIN CUTTING TOOL Russian patent published in 2019 - IPC B23P15/28 

FIELD: physics.

SUBSTANCE: method involves making of holder from at least three layers: support, intermediate and upper, intended for fixation of cutting tool, having different orientation in relation to components of cutting force along axes X, Y and Z. Said layers are made in form of macro layers, which are produced in process of additive technology in medium of protective gas by successive growth of layers of metal powder with controlled orientation of grains by scanning with an energy beam. When creating layers, scanning vector is controlled in parallel between successive layers of macro layers with controlled orientation of grains in each layer in one direction by changing trajectory of scanning through a certain number of layers along thickness of holder with provision of different internal orientation of grains in each macro layer. At that, primary orientation of grains is controlled parallel to tangential component of cutting force, secondary orientation is controlled in local volumes in plane XY in support macro layer of holder in direction of axial component of cutting force, and in upper macro layer - in direction of radial cutting force, macro layer in middle part of holder is formed with periodically variable angle of trajectory of laser scanning in stackable layers in form of porous or honeycomb structure. Protective gas can be argon or nitrogen.

EFFECT: enhanced effect of damping and energy dissipation at transition of oscillation vector between holder layers.
