PROCESS OF LASER TREATMENT AND DEVICE FOR ITS REALIZATION Russian patent published in 1997 - IPC

FIELD: laser treatment of cavities in solid articles manufactured from ceramics, titanium and materials used in medicine for substitution of bones and joints. SUBSTANCE: in compliance with proposed process laser beam is directed at angle to article and is moved reciprocally over trajectories arranged close to one another. Treatment is conducted inlayers in several passages when manufacturing cavities of grooves and annular grooves in solid articles. During one passage article is simultaneously rotated about longitudinal axis and oscillated along it and in direction perpendicular to it. laser beam is oscillated with reference to vertical axis by deflecting it through specified angle. Device for laser treatment has working table for placement of articles mounted for reciprocating motion in horizontal direction, laser with laser head, beam transporting and focusing elements, drive of reciprocating motion of laser head in horizontal direction perpendicular to reciprocating motion of working table and system of program control over laser and movement drives. Rotary working table carries fixture with vertical surface for attachment of articles. EFFECT: provision for optimal productivity and accuracy when forming cavities by change of angle between laser beam and article after removal of each layer of material. 6 cl, 4 dwg
