ABSTRACT:
A positioning process and device (1) for a single crystal (2) for cutting in predetermined directions avoids the adjustment of the cutting machine and minimizes the cutting time by positioning outside of the machine, according to rotational angles (d,g) obtained mathematically from measured and/or imposed data, and which positions the geometric single crystal in a plane perpendicular to the cutting direction (z'") while bringing the cutting plane of the single crystal (2) parallel to the direction of cutting of the machine. The device for practicing the method comprises a frame (5), two cylinders (8) mounted rotatably on the frame and supporting the single crystal (2) and a rotatable plate (12) adapted to maintain the cutting support (3) belonging both to the positioning device (1) and the cutting machine. By a raising mechanism (14), the support (3) and the single crystal (2) are placed in contact and fixed to each other after having effected their predetermined relative orientation by rotation about the axes x and z'". The process and the device permit obtaining exact positioning of the single crystal (2) outside the machine under desirable conditions, a very precise and rapid cutting, and an increase in productivity.
