  • Investigation on surface topography in photochemical machining of Co-Cr L605 alloy using a new etchant for cell growth
    Shrikant Thorat, Deepakkumar H. Patil, Mudigonda Sadaiah, Vikas Sargade
    Progress in Engineering Science, 2025
    The experimental study evaluates surface topography using a suitable etchant in photochemical machining (PCM) of Co-Cr L605 for cell growth on the bio-implants. A new etchant is defined by considering etchant chemistry, the composition of alloying elements, its application, and its implications. Experiments were performed with six different etchants at 50°C for 30 min. The study includes a comparative evaluation based on pH and conductivity, and also analyzes their effects on the depth of etching and surface roughness (R a ). Surface quality was evaluated using a scanning electron microscope (SEM) and a 3D optical profilometer. From the results, a novel etchant was found to be a blend of etching (FeCl3), oxidizing (H2SO4), a reducing agent (HCl), and an alkaline solvent (CH3OH) in weight percentages of 0.09, 0.26, 0.13, and 0.52, respectively. The optimum etch rate and Ra were found to be 0.3 µm/min and 0.85 µm, respectively, for the novel etchant. The confocal imaging technique was used for cell growth examination, and results were supported by contact angle measurements. Overall, the surface topography created by the novel etchant shows better results for cell growth.

  • Study of the effect of PCM process parameters on geometry type, Ra, depth of etch, undercut comparing FeCl3 and CuCl2 etchants on Monel 400
    Deepakkumar Patil, Shrikant Thorat, Mudigonda Sadaiah
    Advances in Materials and Processing Technologies, 2024
    The study mainly focuses on geometrical topographies in photochemical machining (PCM) of Monel 400, using two etchants cupric chloride (CuCl2) and ferric chloride (FeCl3). The experiments were carried out at different etchant concentrations (including a number of chloride ions and weight) and temperatures. A comparative study was carried out on the responses such as depth of etch, undercut, surface roughness (Ra), and geometrical features, viz. etch factor and aspect ratio. This study also implicates the effects of perimeter and geometry type (circle, hexagon, square, rectangle, and triangle) on behaviour of PCM process in the perspective of loss of weight and depth of etching, wherein triangular shape shows 0.1547 µm depth of etching/min and 0.0737 g/min weight loss. The results show that FeCl3 gives 0.8 µm Ra and 13.59 µm/min etch rate with 0.851 etch factor at 80℃ compared to CuCl2. The overall conclusion shows that FeCl3 performs better than CuCl2 in the aspects of PCM for Monel 400.

    Journal of Micromanufacturing, 2024
    Duplex stainless steel (DSS) presents a machining challenge due to its balanced Austenite-Ferrite composition, necessitating substantial coolant usage, elevating machining costs. Research focuses on evaluating the efficacy of PVD coating in dry cutting conditions when conducting orthogonal turning operations on DSS, utilizing WC-Co (uncoated), TiAlN, and TiAlSiN-coated Carbide tools. The assessment encompasses chemical composition analysis, microstructural examination, and characterization through SEM, EDS, XRD, Calo testing, and white light interferometry (Veeco Wyko NT 1900). Findings reveal that the TiAlN-coated tool outperforms others, demonstrating superior performance. While the TiAlSiN coating also displays a notable impact, the presence of oxygen traces compromises its tool performance. In addition to the mentioned analysis, this study simultaneously investigated surface roughness, cutting forces and chip compression ratios. These parameters were comprehensively examined to provide a more comprehensive understanding of the machining processes on DSS using various PVD-coated tools in a dry-cutting environment. This study underscores the significant advantage of employing TiAlN(sputter) coatings for enhancing machining efficiency in dry-cutting environments when dealing with DSS.

    Globally, more than 19,000 fungi are reported to infect agricultural crops with diseases. As the supplier of human energy, crops are seen as being significant. Plant diseases can harm leaves at any point during planting and harvest, greatly reducing crop productivity and the general market’s financial worth. Consequently, the early diagnosis of leaf disease is crucial in farmlands. Agriculture profitability is a key factor in economic growth. This is among the causes why plant disease identification is crucial in the farming sector, as the presence of illness in plants is extremely common. If necessary precautions aren’t followed in these regions, plants suffer major consequences, which impact the grade, volume, or production of the corresponding products. For example, the United States has pine trees that are susceptible to a dangerous illness called small-leaf disease and the backbone of the Indian economy is crop plants. It is advantageous to diagnose plant diseases (Black Spot, other leaf spots, powdery mildew, downy mildew, blight, and canker) using an automated method since it lessens the amount of manpower required to maintain megafarms of crops and does so at an incredibly preliminary phase(when they appear on plant leaves). The computerized identification and classification of plant leaf diseases using an imagery segmented system is presented in this work. It also includes an overview of various disease categorization methods that can be applied to the identification of plant leaf diseases. In order to detect disorders in diverse plant leaves, this study provides a review of diverse plant diseases and several classifying algorithms in deep machine learning.

    Procedia CIRP, 2018
    In this study, Monel 400 was machined using etchants, like ferric chloride (FeCl3) and cupric chloride (CuCl2) at different temperatures, concentration and type of geometry (viz. circular, hexagonal, square, rectangular and triangular). The study focuses on the comparative impact of input process parameters in perspective of depth of etch, undercut, and weight loss. Comparative study of FeCl3 and CuCl2 determines that the overall performance is better for ferric chloride etchant. The undercut observed in FeCl3 was more than CuCl2, but the better geometrical accuracy found with CuCl2 etchant solution. Type of geometries responsible for the depth of etch and weight loss. Triangular geometry shows higher weight loss and depth of etch. Higher weight loss and depth of etch is observed with FeCl3 than CuCl2 etchant. The weight loss and depth of etch increases from 0.0504 g to 0.0737 g and 0.0436 μm to 0.1547 μm respectively for FeCl3 for circular, hexagonal, square, rectangular and triangular shapes. Similarly, for CuCl2 these values are 0.0386 g to 0.0686 g and 0.0236 μm to 0.117 μm respectively.
  • Investigation on effect of grain orientation in photochemical machining of Monel 400
    Deepakkumar Himmatrao Patil, Sadaiah Mudigonda
    Materials and Manufacturing Processes, 2017
    In this study, microchannels with widths of 60, 100, 150, 200, and 250 µm were fabricated on the surface of Monel 400 alloy, and the effect of the rolling direction on the surface finish and etching depth was investigated. The obtained results revealed that the quality of the microchannel surface finish was better along the rolling direction than across the rolling direction, owing to the grain boundary orientations along the (001) plane. In addition, the etching depth increased along the rolling direction due to the presence of residual stress and plastic strain, which ultimately improved the microchannel quality.
  • The Effect of the Rolling Direction, Temperature, and Etching Time on the Photochemical Machining of Monel 400 Microchannels
    Deepakkumar H. Patil, Sadaiah Mudigonda
    Advances in Materials Science and Engineering, 2016
    The present paper describes the effect of the rolling direction on the quality of microchannels manufactured using photochemical machining (PCM) of Monel 400. Experiments were carried out to fabricate microchannels along and across the rolling direction to investigate the effect of the grain orientation on microchannel etching. The input parameters considered were channel width and rolling direction, whereas the depth of etch was the response parameters. Different channels of widths of 60, 100, 150, 200, and 250 μm were etched. The effects of the etching time and temperature of the etchant solution on the undercut and depth of the microchannels were studied. For good quality microchannels, the effects of spinning time, spinning speed, exposure time, and photoresist film strength were also taken into consideration. Optimized values of the above were used for the experimentation. The results show that the depth of etch of the microchannel increases more along the rolling direction than across the rolling direction. The channel width and depth are significantly affected by the etching time and temperature. The proposed study reports an improvement in the quality of microchannels produced using PCM.

  • Some investigations in hard turning of AISI 4340 alloy steel in different cutting environments by CBN insert
    Deepak M. Naigade, Deepakkumar H. Patil, Mudigonda Sadaiah
    International Journal of Machining and Machinability of Materials, 2013
    Generally, hard turning requires large quantity of coolants and lubricants. In the present study, minimal quantity lubrication (MQL) is used for cooling in turning of hardened alloy steel AISI 4340 (45 HRC) with CBN insert of MT KB 5625 grade. The effect of MQL environment on surface roughness, cutting force components is studied and compared with dry and wet environments. The experiments were conducted using Taguchi L18 (21 × 37) mixed orthogonal array. Analysis of variance (ANOVA) of the experimental results shows that depths of cut and cutting environment have statistically 95% significant effect on the cutting force components. The cutting environment is statistically significant at more than 95% confidence level on the surface roughness value (Ra). The surface finish, Ra value for dry and wet turning were 0.49 μm and 0.47 μm, respectively and whereas in MQL turning it is 0.36 μm. It was also observed that tightly coiled chips were formed and can be handled easily during MQL. The study indicates that MQL technique can be environment friendly and form a viable alternative to conventional wet turning.
