Abstract

Nineties represent a revolutionary decade for the technology of roll indention for rebar production. Pushed by the growing demand coming from customers and market, and thanks to the wide potential of the new generation of CNC machines, some machine manufacturers invested in researches for advanced technologies applied to notching machines. As result of this, the best notching machines are today provided with devices and improved automations that make them able to carry out in automatic some operations that, in the past, demanded dedicated manpower.In particular the paper will analyse: the integration of marking operation in the notching machine, the automatic groove and notch centring, the new technologies for notching and marking squared rebars, the tool compensation and rib depth automatic control, the automatic wire-notch edge chamfering for improving the rebar mechanical characteristics. Together with the above, the new ROLLWORK software for Atomat CNC machines will be briefly illustrated. It is based on a revolutionary concept and integrates the programming of the roll maintenance machines, with a software designed to manage the roll shop inventory.
