Electronic cams in punching & bending technology

Electronic cams are a permanent component of modern machines in process technology. They have long-since been established as drive technology and, as you know, offer a series of advantages over other processes. The principle of the electronic cams is based on the calculation of motion profiles, which are transferred to the machine’s control system as tables or parameters. A system operating with electronic cams requires powerful software to achieve optimal motion sequences. This is the only way to ensure that the machine operates quietly and effectively with low wear. The fact that a control system using electronic cams can also produce extremely high forces can be demonstrated on the 2000 kN NC press produced by Schmale. The machine is conveniently operated and programmed by the input of a few data by touchscreen. In fractions of a second, the machine then produces the electronic cams for controlling the servo-electrical axis. In the system design, Schmale intentionally developed a user interface which delivers the desired results simply and transparently. This makes it possible to work with the new technology quickly and conveniently from the very first commissioning without long training periods.
