Device for simulation of self-excited vibrations in lathe turning

Abstract

The invention relates to a device for simulating the development of self-vibrations during turning. The device, according to the invention, uses a specimen (67) of the material under investigation, placed on a sled (6), which can move along vertical columns (2), immobilized in a support piece (1), to the support piece (1) being attached a cylindrical component (12), by means of which the device will be fixed in one of the four locations of a support (A) tool holder of a universal lathe, and a sled (6), in contact with two springs (8 and 9), will be forced to move along the columns (2 and 3), as a result of the friction force between the surface involved in the process of the specimen (7) and the outer surface of a disk (17), in rotational motion, the disk (17) being placed on a mandrel (18), oriented and fixed in turn in a universal chuck (B) of a lathe and respectively in a rotating tip (C) .
