Abstract
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 (Δti), a torque (M(ti,) M′(ti)) of the tool head is measured for each time increment (Δti) and an individual energy consumption (E(Δti), E′(Δti)) is determined for each time increment (Δti), said individual energy consumption corresponding to an individual quantity of material abraded during the time increment (Δti), 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(Δti), E′(Δti)), said total energy consumption corresponding to the total quantity of abraded material.
