FIELD: process engineering.
SUBSTANCE: proposed method comprises two stages of machining, at least, one 3D microstructure by cutting to remove functional layer material with the help of polyhedral, primarily, trihedral pyramidal cutting tool, every side of which making tool front surface. To up the precision, roughing is performed by high-speed milling to remove main part of functional layer material in said microstructure and provide for allowance for finishing. Said finishing is made in one pass along the microstructure contour by planning at second stage. Note here that first and second stages are performed by aforesaid one tool.
EFFECT: higher precision.
