AUTOMATED ELECTRIC DRIVE OF TECHNOLOGICAL OBJECTS WITH ELECTRONIC SYNCHRONIZATION OF MECHANISMS’ MOVEMENT DOI: 10.22184/2499-9407.2021.23.2.52.55
Moving away from coupled kinematics and moving to a single coupled electric drive can improve productivity, reduce operator skill requirements, and achieve higher end product accuracy. The article considers decoupling of the kinematics of the 53A30 gear hobbing machine with the use of electronic synchronization of the tool and the workpiece. It also reviews a variant of electronic synchronization in hot stamping machines.
