“…The TW-ECDM process is steadier than W-EDM and gives a better surface finish when contrasted with ECM. In the TW-ECDM process, both the electric discharge erosion and electrochemical dissolution (ESD) impacts are utilized for the evacuation of the material [ 26 ]. This helps to machine the workpiece and electrochemical dissolution gives a better and smoother surface finish.…”

Many microslits are typically manufactured on quartz substrates and are used to improve their industrial performance. The fabrication of microslits on quartz is difficult and expensive to achieve using recent traditional machining processes due to its hardness, electrically insulating nature, and brittleness. The key objective of the current study was to demonstrate the fabrication of microslits on quartz material through a magnetohydrodynamics (MHD)-assisted traveling wire-electrochemical discharge micromachining process. Hydrogen gas bubbles were concentrated around the entire wire surface during electrolysis. This led to a less active dynamic region of the wire electrode, which decreased the adequacy of the electrolysis process and the machining effectiveness. The test results affirmed that the MHD convection approach evacuated the gas bubbles more rapidly and improved the void fraction in the gas bubble scattering layer. Furthermore, the improvements in the material removal rate and length of the cut were 85.28% and 48.86%, respectively, and the surface roughness was reduced by 30.39% using the MHD approach. A crossover methodology with a Taguchi design and ANOVA was utilized to study the machining performance. This exploratory investigation gives an unused strategy that shows a few advantages over the traditional TW-ECDM process.

“…Bian et al 21 used a spiral tungsten carbide tool (Ø 400 mm) to study the influence of voltage (ranges from 28 to 64 V) on tool wear. They reveal that almost zero tool loss was noticed below 44 V, and tool loss sharply increases.…”

Micro-electrochemical spark machining (µ-ECSM) is an advanced hybrid machining approach to machine materials, irrespective of their electrical conductivity. This article illustrates the state-of-the-art review of the current research on the wear mechanism of micro-tool electrodes used in the µ-ECSM process. The influence of different electrical and non-electrical machining parameters on tool wear rate, inducing dimensional inaccuracies in the fabricated components, has been addressed. The various parameters of the tool, such as the material, surface morphology and texture, shape, and size, which influence the process performance, have been discussed in detail. The requirement for technological development in the tooling area of the µ-ECSM process has been pointed out. A detailed analysis of the aforementioned areas is present in this article.

At present, ever higher demands are placed on the quality of products. The success of organizations in the global market depends mainly on measuring and evaluating their products quality. A set of measurable criteria usually determines product quality. There are many technological processes in the structure of a production organization that is statistically unstable. The norms of ISO class 9000 emphasize statistical process control, known as SPC (Statistical Process Control). They represent a methodology for eliminating the causes of instability of production or technological process. The paper deals with the application of control charts for the technological process of rock disintegration by rotary drilling. The measured values of the dynamic system drilling tool-rock in working mode are processed. The control charts are applied to the input (control) variables of the pressure force-F (N), revolutions-n (rpm), and the output measured variable of the vibration signal of the acceleration. The article constructs and presents the resulting important control charts for the technological process of rock disintegration by rotary drilling. It is essential that for the technological process of rock drilling, the variables that enter and exit the dynamic system must be statistically manageable. The stable state of the input technical parameters (revolutions and pressure force) of the drilling tool is essential from the technological, performance, and economic point of view. The stable state of the output parameters is of significant importance in preventing the emergency state, excessive wear of the drilling equipment and optimizing the optimal operating mode. Industrial practice points out that the correct application of statistical regulation stabilizes the technological process, increasing the quality and productivity of work.
