Abstract (en)

[origin: EP0754511A2] The process uses rolling tools and a drive unit with drive engine. The drive unit is braked or accelerated, pref. close to the tool, to compensate for tolerance in the drive unit. The unit is braked, when the tool engages in the workpiece, and the brake force is lifted shortly after rolling is finished. Braking is hydro-dynamic, and pref. computer-controlled. The braking momentum is smaller than the drive momentum, thereby maintaining constant the drive speed of the drive unit.
