“…It might be caused by the dramatic changes in the current density during the quick movement of the nozzle in the Jet-ECM surface figuring process. 31 The machined depth, the overcut zone, and the stray corrosion zone were sensitive to the moving speed of the nozzle. 31 The higher moving speed of the nozzle would lead to a decrease in the machined depth, but the size of the stray corrosion zone increased with a higher speed.…”

“…19,23,24 Based on the high machining flexibility of Jet-ECM 25 and the principle of computer-controlled optical surfacing (CCOS), through controlling the trajectory and dwelling time of the nozzle, the amount of material removal at different positions of the workpiece can be manipulated. [26][27][28] Therefore, Jet-ECM can manufacture flat or wavy surfaces 19 as well as various kinds of structures on the workpiece such as pits, 26,29 grooves, 30,31 or other complex structures 32,33 for different industrial applications. In previous studies, Natsu et al (2007) 32 proposed an algorithm to obtain the nozzle traveling path and scanning speed to generate a complicated groove (diameter: 2 mm, depth: 100 μm) by superimposing simple patterns.…”

Ultra-flat and ultra-smooth copper (Cu) surfaces are widely used as optical mirrors, heat sinks, and substrates for functional material growth. Traditional polishing methods that rely on abrasive particles are easy to induce mechanical defects such as abrasives embedding and scratches on surfaces. A new stress-free machining process is proposed in this research to fabricate an ultra-flat and ultra-smooth Cu surface by combining jet electrochemical machining (Jet-ECM) and electrochemical polishing (ECP). With the accurate manipulating of material removal rate (MRR) and planning of nozzle trajectory, an ultra-flat surface can be obtained efficiently in the Jet-ECM process. The surface roughness of the workpiece can be further improved by ECP with the same electrolyte used in the Jet-ECM process. The results show that the surface peak-to-valley (PV) value which indicated the surface form error of the Cu surface was reduced from 4.4 μm to 1.7 μm and the surface roughness Sa was reduced from 70.3 nm to 13.5 nm. The combination of Jet-ECM and ECP which share the same electrolyte and apparatus can improve the surface flatness and roughness significantly. This study improves the machining accuracy of stress-free machining methods and has great implications for the further understanding of the electrochemical removal mechanism.

An overview of conventional and non-conventional techniques for machining of titanium alloys

Machining is one of the major contributors to the high cost of titanium-based components. This is as a result of severe tool wear and high volume of waste generated from the workpiece. Research efforts seeking to reduce the cost of titanium alloys have explored the possibility of either eliminating machining as a processing step or optimising parameters for machining titanium alloys. Since the former is still at the infant stage, this article provides a review on the common machining techniques that were used for processing titanium-based components. These techniques are classified into two major categories based on the type of contact between the titanium workpiece and the tool. The two categories were dubbed conventional and non-conventional machining techniques. Most of the parameters that are associated with these techniques and their corresponding machinability indicators were presented. The common machinability indicators that are covered in this review include surface roughness, cutting forces, tool wear rate, chip formation and material removal rate. However, surface roughness, tool wear rate and metal removal rate were emphasised. The critical or optimum combination of parameters for achieving improved machinability was also highlighted. Some recommendations on future research directions are made.

“…Chai et al [6] analyzed the influence of the flow field distribution in the inter-electrode gap on the machining accuracy and stability of the cooling holes of the blade. Liu et al [7] studied the surface quality of titanium alloy processed by electrochemical jet. Simulations and experiments have found that the voltage is 24 V, the gap between electrodes is 0.6 mm, the electrolyte flow rate is 2.1 L•min-1 and the nozzle travel speed is 25 μm•s-1, which can obtain good processing quality.…”

To fully understand the electrochemical machining profile, a multi-physics coupling simulation model including flow-electric-temperature-structure field were established to analyze the corrosion process of the anode material and the change trend of temperature,hydrogen volume fraction, electrolyte conductivity and current density in the processing gap.The analysis results show that the temperature and hydrogen content gradually increase along the process direction.The current density and material removal showed a parabolic trend of the upper opening and the lower opening, respectively.The simulation of the different physical field changes in the electrochemical machining blade profile can not only better understand the complex physical phenomena in the machining, but also provide a theoretical basis for the selection of actual electrochemical machining parameters.
