FIELD: machine engineering, possibly laser cutting of different materials. ^ SUBSTANCE: apparatus includes optical laser head, probe, displacement pickup. The last is in the form of digital signal source having two spring-loaded one relative to other separate plates. Probe includes regulated along height rod joined with one of said plates. One plate is spring-loaded by means of reverse-action springs mounted in rod; other plate is spring-loaded by means of lead screw mounted in head. Apparatus provides continuous conversion of analog signals to digital ones. ^ EFFECT: enhanced accuracy and efficiency of working blanks due to continuous measurement of distance between focal point of optical laser head and worked surface. ^ 1 cl, 1 dwg |
