DEVICE FOR AUTOMATICALLY CORRECTING SIZE-ADJUSTMENT OF NUMERICALLY CONTROLLED LATHE TOOLS Russian patent published in 1994 - IPC

FIELD: machine tool manufacture. SUBSTANCE: device has pickup that monitors the position of cutting edge of tool in X and Z system of coordinates in the form of interruption processing unit through which circuit of the tool is made and broken. The unit distributes electrical signals or control pulses and conveys pulses to actuating mechanisms of tool drive. The tool mounted in replaceable tool block functions as a movable contact of first unit locked in socket of support. Flat platforms and cleaning members at either sides of the platforms act as fixed contacts of the pickup. Output of interpolator of numerical control system and movable and fixed contacts of the pickup act as input of the interruption processing unit. Control units are connected to correction block of numerical control unit and to interruption processing unit. EFFECT: enhanced accuracy of correction. 4 cl, 6 dwg
