FIELD: process engineering.
SUBSTANCE: invention relates to cutting by abrasive water jet. The part is continuously cut from disc-shaped material block with the help of ejection head arranged opposite the block first opposite outer surface. Continuous cutting is performed with making of connecting line between the block second outer surface opposite said first surface and the block cut-out surface. At least, one cutting of part is executed on, at least a part of block depth including at least the part of said connection line with the help of said ejection head located opposite said second outer surface of the block.
EFFECT: higher rate of cutting.
