A method for machining a longitudinal profile section having an actual length and a first and a second end, wherein the first and the second end are machined using respectively a first and a second tool head and material is continuously abraded by the first and second rotating tool head during a machining period, the machining period is divided into time increments (&Dgr;ti), a torque (M(ti,) M′(ti)) of the tool head is measured for each time increment (&Dgr;ti) and an individual energy consumption (E(&Dgr;ti), E′(&Dgr;ti)) is determined for each time increment (&Dgr;ti), said individual energy consumption corresponding to an individual quantity of material abraded during the time increment (&Dgr;ti), and a total energy consumption (E(t), E′(t)) both of the first and of the second tool head is determined from the individual energy consumptions (E(&Dgr;ti), E′(&Dgr;ti)), said total energy consumption corresponding to the total quantity of abraded material. |
