“…The investigation conducted by Teicher et al [7] deals with the improvement of the grindability of the Ti-6al-4V alloy by the use of cryogenic cooling to reduce the contact zone temperature, thereby preventing the chemical interaction between the workpiece and tool. rao [8] summarizes that cryogenic machining with ln 2 is safe and environmental friendly. nitrogen is a nonhazardous gas that constitutes 79 % of atmospheric air.…”

Based on the number of previous studies, this study aims to investigate the effects of process parameters of an Electrochemical Machining process which are electrolyte concentration, voltage applied to the machine, feed rate of the electrode and Inter-Electrode Gap between tool and work -piece. Aluminum samples of 25 mm diameter x 25 mm height and 30mm diameter x 25mm height of the tool is made up of copper with a circular cross section with 2 mm internal hole. The design of the system is based on the Taguchi method. Here, the signal-to-noise (S/N) model, the analysis of variance (ANOVA) and regression analyses are applied to determine optimal levels and to investigate the effects of these parameters on surface quality. Finally, the experiments that use the optimal levels of machining parameters are conducted to verify the effects of the process parameters to the surface quality of the products. The results pointed a set of optimal parameters of the ECM process. The Inter-Electrode Gap between tool and work -piece has extremely effected on these Material Removal Rate and surface roughness. The Material Removal Rate increases with diseases in Inter-Electrode Gap, and Ra diseases with diseases in Inter-Electrode Gap. The experimental results show that maximum Material Removal Rate have obtained with electrolyte concentration at 100 g/l, feed rate at 0.0375 mm/min, voltage at 15V, and Inter-Electrode Gap at 0.5mm. The minimum Ra have obtained with electrolyte concentration at 80 g/l, feed rate at 0.0468 mm/min, voltage at 10V, and Inter-Electrode Gap at 0.5mm. This results has led to need studies on these parameters in Electrochemical Machining which are improving productivities and surface roughness of the products.

“…This may be due to the extreme hardness of the CVD diamonds which accordingly increases the sensitivity of the CVD diamonds to crack. Moreover, when the abrasive wheel is suddenly contacted with the CVD diamond there is a sharp increase of the grinding forces which causes strong mechanical shock; this mechanical shock may results in the micro-fractures of the cutting edge [5][6][7][8]. Hence in order to overcome these problems and obtain sharp, regular, high precision and high efficiency cutting edges with low stress, chemical mechanical sharpening should be performed.…”

This Research is Focused on the Chemical Mechanical Sharpening of CVD Diamond Micro Tool, which has High Strength and Good Wear Resistance. the Diamond Grinding Wheels were Usually Used for Sharpening, but this Method could Not get High Quality Surface of the Diamond Efficiently and Small Cutting Edge Radius. in Order to Seek a Better Mode for Sharpening, the Copper Based Tungsten Carbide Disc and Abrasive were Used for Grinding. for Better Understanding the Effects of Different Parameters on the Grinding Process and Optimizing them, the Orthogonal Method was Used to Design the Experiments. Grinding Direction, Feed Rate and the Grinding Velocity were Investigated to Obtain Sharper Cutting Edge and Smooth Flank Face. Analysis of Range was Also Introduced to Evaluate the Contribution of each Parameter in Orthogonal Experiment. the Results Showed that down Grinding, Medium Feed Rate and Low Velocity could Achieve a Better Sharpening Result.
