In the paper there are emphasized problems connected with the use of diamond metal bond abrasive discs at the processing of hard alloys. The reasons of cutting capacity decrease are pointed out which limit a wide-spread use of a diamond metal bond tool. It is established that for the achievement of a required productivity and quality of ready products is possible at the expense of the application of electro-chemical and electro-physical methods of stropping and also due to the improvement of abrasive disc designs. This work reports the investigations of a cutting capacity of diamond discs at the working of hard alloys by a combined method of electro-chemical grinding with simultaneous continuous stropping. As an output parameter there was accepted a cutting capacity factor of a diamond which was assesses according to the changes in effective working capacity. On the basis of the results of the experimental data processed there were obtained theoretical models of the dependence of the cutting capacity factor upon electric and mechanical constituents of the modes of combined electro-chemical grinding. A complex of investigations directed to the detection of efficient modes ensuring the stability of cutting capacity in diamond metal bond discs is carried out. It is experimentally confirmed that the application of the method of combined electro-chemical grinding with the simultaneous continuous disc stropping at working hard alloy materials allows increasing diamond disc cutting capacity by 15% in comparison with other methods of the diamond working of such materials.

Prepared Composite

ABSTRACTA procedure for batch processing of up to four specimens for cross-sectional transmission electron microscopy (X-TEM) has been developed. The technique is essentially an extension of the standard multi-slice composite full disc sample preparation method. However, disc cutting and dimple grinding steps have been eliminated. The trimming, gluing, stacking, and sectioning of the wafers from the original sample material to produce composite transverse sections are identical to those of the standard scheme. Grinding and polishing of the sections are carried out in a batch mode which, in turn, reduces the overall processing time per specimen. The prepared composite foils are mounted on metallic disc grids which provide structural support during ion thinning and microscopy.

Cutting Unit

The paper presents the construction of a new research station for studying the cutting process of energy plants. The station consists of 3 basic units: a truck with drive and cutting units, a frame which is a guide for the truck moving on it, and a base for placing the plant’s stems. The station allows to determine the unitary energy of the cutting process for various rotary and travelling speeds of the cutting unit and for various sizes, spacing and angles of inclination of the cutting discs. It also allows to form freely the cut plants’ stems’ sockets.

Abstract The article presents the methodology of introducing automatic carbon fiber panel cutting technologies at the Composite Testing Laboratory of the Institute of Aviation. It describes the process of implementing the new cutting technology which boosts the efficiency of preparing composite samples for strength testing, with the requirements applicable to edge smoothness and dimension tolerances taken into consideration. It also reviews the literature concerned with three most popular composite material cutting methods: laser cutting, abrasive water jet cutting and machining, presenting the strong and the weak points of each one of them. After selecting the machining technology relying on a disc, cutting tests have been performed. Cutting discs coated with diamond particles, and carbon fiber panels were used during the tests. The tests were performed with the use of the INFOTEC CNC machine, with an adapter enabling the installation of cutting discs with the maximum diameter of 150 mm.

Tools And Methods

This work is aimed at improvement of durability of especially thin disc tools, by means of controlling their dynamic parameters. It was found out that it is necessary to design tools and methods of reducing oscillations of the tool’s structure that could allow designing tools with thin and especially thin cutting pieces, ensuring the specified parameters of its durability, cutting precision and improvement of cutting modes. The performed investigations allow reducing substantially the cut’s width and ensuring the prescribed parameters of the tool’s durability, thus improving the overall technical and economic parameters of blanks cutting.
