DEVICE FOR CONTROLLING FEED DRIVES OF TWO-FUNCTIONAL ELEMENTS OF EQUIVALENT DRIVING COORDINATES OF GEAR SHAPER

摘要

FIELD: machine-tool manufacture. SUBSTANCE: correcting signal is shaped concurrently with the setting signal for electric motors of both coordinates, said correcting signal being proportionate to the difference of actual speeds of coordinates. Correcting signal of lagging coordinate is added to the control one while that of the leading coordinate is subtracted from control signal. EFFECT: improved design. 2 dwg
