| 摘要 |
The invention relates to a method for machining a longitudinal section (1) having an actual length (L1) and a first and second end (3, 3'), whereby the first and second ends (3, 3') are machined using a first and second tool head (6, 7) and material is continuously abraded by means of the first and second rotating tool head (6, 7) during a machining period. The machining period (t) is divided into time increments (?ti), a torque (M(ti,) M'(ti)) of the tool head (6, 7) is measured for each time increment (?ti) and an individual energy consumption (E(?ti), E'(?ti)) is calculated for each time increment (?ti), said consumption corresponding to the individual quantity of material abraded during the time increment (?ti). A total energy consumption (E(t), E'(t)) of both the first and second tool heads (6, 7), said consumption corresponding to the total quantity of abraded material, is calculated from the individual energy consumptions (E(?ti), E'(?ti)). |
