| description | The paper is devoted to a physical modeling of the process pertaining to interaction of the machined material with metal deposits along a hole edge which are obtained on a smooth tool surface due to its electro-erosion modification. A technique for obtaining single holes on a cutting tool (strip) is given in the paper. The paper describes main geometric elements which have obtained due to the action of a single electric discharge. Geometric parameters of a single hole initiated on a working strip surface in the course of this effect have been given in the paper. The paper provides a justification and description of a tape tool prototype used in the investigations brass band strips, on which a washer with different rounding radius of an outer edge is fixed. The prototype makes it possible to simulate metal deposits on the modified working surface of the strips. The paper presents methodology for carrying out experiments on investigations for interaction of the created strip prototype with a processed material, including a description of a device for studying the process of washer interaction with the samples from paraffin and gypsum. Photographs are given that allow to visualize a destruction process of samples which is caused by a washer (model of metal deposits). The paper shows stages of sample fracture when using washers with different rounding radius and describes nature of the destruction for various sample materials. The results of the conducted studies reflecting an influence of the shape of an outer washer edge, in particular a radius of its rounding, on the course of characteristic stages in the process of destruction of samples from paraffin and gypsum are presented and discussed in the paper. It has been experimentally confirmed that metal deposits which are formed at the hole edge and extend beyond an initial surface contour, represent cutting-deforming elements with a capability to destroy material which ranks below in hardness to metal of the deposits. |
