FIELD: measuring engineering.
SUBSTANCE: method comprises setting the article to be controlled on the movable traverse gear having two extent of freedom, illuminating the surface of the article by light, receiving the light reflected from the surface of the article with the use of a photodetector, moving the article parallel to the X-axis, determining coordinates of the light spots on the photodetectors of the current values of the heights of the article shape, locking the position of the table, scanning the main section of the article shape, comparing it with the reference one , and determining the quality of the article shape. The main section is scanned by moving the article parallel to the Y-axis, when the traverse gear is in a position determined from the formula proposed. The device comprises unmovable horizontal base, vertical cantilever secured to the base, unit for measuring the article shape mounted on the vertical cantilever, two carriages that define a traverse gear and provided with the individual drives controlled by a computer, and pickup of linear movements. The first carriage moves parallel to the X-axis, and the second carriage is mounted on the first one and moves parallel Y-axis.
EFFECT: improved quality of control.
