Optimization of Bellows and Tubes Cutting by Disc Knife to Achieve the Minimum Burr Size

Original language description

The paper solves the determination of the optimal size of the shear gap when dividing components with a circular cross-section (hydroformed metal bellows and tubes) with a disc knife to achieve the smallest size of burrs on the divided surfaces. Analyzes were performed on bellows with an outer diameter of 15 mm and a wall thickness of 0.4 mm, which were made of material 1.4541/X6CrNiTiB18-10. During the experiments, the size of the shear gap between the inner disc knife and the outer knife was changed in the range of 0.04-0.10 mm by 0.01 mm, and the pressing force of the inner disc knife was changed (values of 0.20 and 0.25 MPa). The experiments were performed using a cutting tool after 20,000 cuts and after 120,000 cuts, i.e. with different wear. Graphical dependences were constructed from the measured values and the optimal size of the cutting gap was determined, which allows achieving the minimum size of the burr and thus shorten the time for its removal by brushing or tumbling in the subsequent operation. The mentioned procedure of optimization of division technology can be applied to analogous cases of division.
