Embodiment Construction

[0029] figure 1 The pipe cutting part 1 is shown clamped in a clamp not depicted. The pipe cutting part 1 is clamped in a shape shown by the rectangular boundary outside the side view with an actual length L1, and during execution of the machining method, figure 1 The hatched area 2 is chipped and the tube cutting part 1 is shortened to the machining length L2.

[0030] The pipe is cut into pipe cut pieces 1 with a pipe cutter. By cutting, the pipe cutter 1 has sharp edges at its pipe cutter end 3 and at the other pipe cutter end 3'. By cutting the tube, a tube cutting element 1 of actual length L1 is formed, in particular sawn or cut. In the longitudinal direction L, the actual length L1 matches the longitudinal extension of the tube cutting element 1 in its rectangular profile. After cutting, the tube cut piece 1 is processed by means of two tool heads ( 6 , 7 ), which rotate simultaneously and oppositely about the same axis of rotation R. Each tool head (6, 7) will mac...

Abstract

The invention relates to a method for machining a long profile cut piece (1) having a real length (L1) and a first and a second end (3, 3'), by means of a first or second tool head (6 , 7) Machining the first and second ends (3, 3'), and during the machining duration, the material is continuously cut by the first and second rotating tool heads (6, 7); the machining duration (t) is divided into time increments (Δti), through which the torques (M(ti), M'(ti)) of the tool head (6, 7) are measured respectively, and each time increment (Δti ) to calculate the single energy consumption (E(Δti), E'(Δti)) related to the amount of material cut in the time increment (Δti) period, and from the single energy consumption (E(Δti), The total energy consumption (E(t), E'(t)) of the first and second tool head (6, 7) in relation to the total amount of material removed is calculated in E'(Δti)).

Description

technical field [0001] The invention relates to a method for machining workpieces. [0002] A method well known in the prior art for machining workpieces, in particular shaped as cut-outs of long sections. Background technique [0003] As a rule, the workpiece as a tube cut piece is cut from the tube, and the two ends of the tube cut piece are subjected to further processing, such as washing, chamfering, brushing. When chamfering the two ends of the cut pipe cut piece, the inner-outer chamfer and the design volume (Planma β) are chamfered (aufgefast) by each tool head on the two pipe ends. During chamfering, the overall length of the tube is reduced from the actual length to the machined length. Both ends shall each have a completely smooth design volume and the same inside-outside chamfer. The amount of material cut from the design amount, the design machining allowance (Planaufmaβ), should be as small as possible in order to reduce material waste. [0004] During chamf...
