Summary: This study investigates the abrasive wear of electroplated diamond belt in grinding nickel-based superalloys through experimental research. The results show that increased grinding speed and normal force contribute to higher grinding temperature and more severe belt wear. The wear mechanism of diamond grit includes physical wear modes like abrasion, fracture, and pull-off, as well as chemical wear.

Summary: This paper investigates the fabrication and evaluation of electroplated Ni-B-diamond grinding tools made with martensitic AISI 440C rod substrates. Experimental results show that the diamond density in a diamond-contained composite deposit is influenced by the timings of intermittent stirring cycles. Suitable composite hardness and machining conditions are identified. The method performs well in slot grinding tests.

Summary: The wear characteristics of micro-structured CVD-D grinding tools were studied and compared with micro-structured CGDE and FGDMB grinding tools. The results showed that the micro-structured CVD-D tools had better wear resistance, higher grinding ratio, and lower grinding force. The wear form of the CVD-D tools was the shedding of the coating at the edge of the micro-structure, without graphitization wear observed.

Summary: This paper introduces a diamond wire electrical discharge sawing (DWEDS) method that integrates the advantages of diamond wire sawing (DWS) and electrical discharge machining (EDM), which has higher sawing efficiency and better kerf loss, wire mark, and surface uniformity compared to current DWS method. A new method for evaluating efficiency considering wire bow and kerf width was proposed, and it was found that DWEDS has higher efficiency and better silicon loss compared to EDM and DWS.

Summary: In this paper, a novel three-dimensional surface topography model of original CVD diamond grinding wheels was established based on multiple random data. The model was simulated to analyze the grinding process and its performance was verified through grinding experiments. The influence of grinding parameters and wheel wear on the grinding performance was discussed, and micro-structured CVD grinding wheel models were presented by coupling different forms of micro-structures. These findings provide a quantitative and effective method for the design of CVD diamond grinding wheels and their surface structuring.

Summary: This study uses electroplated diamond abrasive belts (EDAB) to grind Inconel718. It is found that EDAB shows stable grinding performance, and the wear mechanism in different wear stages is primarily micro cleavage fracture, macro cleavage fracture, and adhesive wear. With the wear of EDAB, the surface roughness decreases and reaches a minimum of Ra0.5μm, and the subsurface crystalline grains of Inconel718 are refined. Furthermore, the use of low-hardness contact wheels significantly reduces abrasive belt wear and improves surface integrity.

Summary: Micro-fabrication has become increasingly significant in aerospace, biomedicine, and other industries. Due to its excellent wear resistance, CVD diamond shows great potential in the production of micro-grinding tools. This study demonstrates that the structured CVD diamond micro-grinding tool exhibits superior machining precision and wear resistance based on surface roughness and burr size analysis after machining. Moreover, analysis of force signals reveals that the structured CVD diamond micro-grinding tool reduces the axial force by 20% and the radial force by 10%, indicating higher cutting efficiency. Furthermore, through time domain analysis, the relationship between acoustic emission signal characteristics and surface roughness is established. By employing wavelet transform and machine learning, the wear degree of common and structured CVD diamond micro-grinding tools is accurately predicted with a success rate over 99%.

Summary: This study established a strength distribution model for micro diamond tools considering diamond anisotropy and chip flow direction. The comprehensive wear resistances of micro diamond tools with different crystal orientation combinations were analyzed based on the model. The wear prone areas of different tools were successfully predicted. Additionally, the evolution processes of sharpness and wear topography were monitored, and the morphologies, profile errors, and topological characteristics of the micro-structures machined with different micro diamond tools were analyzed.
