Abstract: The secondary development of Pro/E NC Processing tool-database is carried out by the use of Pro/Toolkit and Access2003, which is based on VC++. The study can solve the problem of inputting a great number of parameters during simulation processing, and can also realize parametric design of diamond saw blade. It is researched to extend the applying of the CAM model of Pro/E in the stone cutting processing. In this study, it is realized to communicate data sources of saw blade parameter, Pro/Toolkit procedures and MFC application program by DLL, in order to finish use of database by means of activating menu and dialogue box. All above makes the diamond saw blade library work during NC Processing. Because the function of Pro/Toolkit sdk is fully developed, the special requirement of the stone industry for Pro/NC can be satisfied.

Abstract: In this paper X-ray and penetrant inspection were applied to detect flaws in welding zone between diamond segment and matrix in order to detect position and form of the flaw. The result can be used to assess weld quality and performance of diamond saw blade. The result shows that main flaws on welding zone are crack, incomplete fusion, lack of fusion, pore. These flaws can affect the life and machining precision of the diamond saw blade. We can improve the welding process to ensure welding quality and reliability of saw blade by detected flaws.

Abstract: In this paper, it is assumed that diamond’s cross-section is hexagonal, which is similar to the actual condition. At first the diamond cutting depth of diamond drill bits and diamond saw blades has been calculated and analyzed. A variety of diamond size and diamond exposure difference has also been calculated and analyzed. It is shown that the cutting depth of single diamond was generally below 0.02mm and the difference on diamond exposure between coarse and fine diamond must be less than diamond cutting depth to achieve efficient rock breaking. Some diamond size design methods are acquired via the calculations and analysis.

Abstract: The process of cutting granite material is simulated with using analysis of LS-DYNA finite element. The stress, strain and cutting force of a diamond saw blade are analyzed when cutting granite materials. Then the stress-strain distribution and cutting force curve of the diamond saw blade can be got in the process of cutting granite materials and a conclusion of the change rule of the cutting force is also obtained. When the diamond saw blade just contacts the workpiece, the cutting force rises gradually and after entering the certain cutting depth, the cutting force fluctuates in a very small range. Through the simulation, the theory of FEM model to calculate granite materials cutting force is obtained. By changing the parameters of the diamond saw blades, the influence of all parameters on cutting force of diamond saw blade is analyzed .A diamond saw blade's structure is optimized, when the parameters of saw blades is suitably selected. The processing performance of a diamond saw blade is improved further, and the result has important practical significance to process the granite material.

Abstract: The structure reliability of the diamond saw blade in milling process is studied. With probability design features of ANSYS, take the flange diameter ,thickness, diameter of the diamond saw blade and load suffered in the milling process as input variables, and take the maximum equivalent stress of dangerous parts of the diamond saw blades stress as output variable. The diamond saw blade structure reliability is analysed using Monte Carlo method and the maximum equivalent stress value cumulative distribution and dangerous parts of various parameters on the distribution of the maximum equivalent stress sensitivity under the impact of the load are got. The result provides a theoretical basis for improving the parameters of diamond saw blade and has the significant practical and theoretical value for the stone processing theory and diamond saw blade study.

Abstract: Powder metallurgy-based technologies of saw blades production for stone cutting normally uses cobalt as binder agent. Cobalt was chosen for that purpose because it provides improved properties, high wettability and good adhesion between dispersed diamond particles. In addition to its excellent physical properties, cobalt also shows a positive behavior associated with the control of diamond graphitization at temperatures up to 1000°C. In this work, an experimental planning method supported by a mathematical algorithm was used to study the influence of doping agents incorporated into cobalt-based binders. The consequences on the wear resistance of saw blades, as well as on other physical and mechanical properties of the “diamond-cobalt-doping agent” composites were investigated. Cr3C2, Si, Ni and Fe were used as doping agents. Experimental tests were carried out using granite as a base material for wear and cutting operations.

Abstract: By FEM module analysis and temperature distribution analysis of diamond saw blade with multi-holes base and different segment width, influence of different hole diameter, hole number and segment width to nature frequency is clear. Adopted single-factor test, sawing force and acoustic emission signal are measured by cutting several kinds of strength concrete in different cutting parameters. The analysis to characters of sawing force and acoustic emission helps to find out optimum structure of diamond saw blade with different segment width, more rational sawing parameter and its adaptability to workpiece material.
