The experiment aims to study the tribological properties of PTFE composite with graphite filler as additive. The specimens are prepared with the concept of Powder metallurgy, varying the percentage of additive material. Four different specimens with variation in percentage of additive is prepared for the purpose of experimentation. The technique of taguchi orthogonal array is involved in design of experiments. Tribological tests were conducted by varying the load and Disc speed while sliding distance was maintained constant. Pin on Disc tribometer was employed to conduct the wear tests. The effect of filler content, load, wear on its tribological properties was observed in this study through ANOVA. Experimentation on specimens reveal that 24% graphite added to PTFE composite had less susceptibility to wear. The most influencing input parameter on tribological properties are observed to be filler content.

P. V. S. Subhashini, Amulya, N., and Y. P. Deepthi, “Parametric Optimization of Surface Roughness of Deburring Process on Aluminum Alloy Using SCARA Manipulator”, Materials Today: Proceedings, vol. 5. Elsevier Ltd, pp. 24313-24322, 2018.[Abstract]

This paper presents an attempt to analyze deburring operation using a SCARA (Selective Compliance Articulated Robot Arm) manipulator. There are various deburring techniques available in the literature but this work aims at deburring of small sized components. In this paper parametric optimization of surface roughness using SCARA Manipulator using various deburring parameters has been performed with Genetic and TLBO optimization algorithms. A rectangular work piece of Aluminum is considered and the end effector used in this case is a grinding wheel of aluminum oxide. The machining parameters considered are Spindle speed, Feed rate and Depth of cut. An orthogonal array L9 was modeled using Taguchi Method to conduct the experiments. The surface roughness of the workpiece is measured using an instrument called Talysurf. Later the end effector of SCARA is used for deburring on the same workpiece to check the efficiency of SCARA for removal of burrs. Regression analysis is employed to analyze the effect of the deburring parameters on material. Optimization of parameters was done using Genetic and TLBO algorithms in MATLAB environment. An optimum deburring parameters for minimizing the surface roughness was obtained at the Spindle speed 5250 (rpm), feed rate 0.859 (mm/sec) and depth of cut 0.3 (mm) and Spindle speed was found to be the most significant factor followed by feed rate for Surface roughness.

Y. P. Deepthi and Krishna, M., “Optimization of Electroless Copper Coating Parameters on Graphite Particles Using Taguchi and Grey Relational Analysis”, International Conference on Materials Manufacturing and Modelling (ICMMM - 2017), vol. 5. Elsevier Ltd, VIT, Vellore, TN, pp. 12077-12082, 2018.[Abstract]

Electroless process is employed to get uniform coating of copper on graphite particles. Electroless coating process was performed based on Taguchi L16 orthogonal array. Optimal coating parameters were determined by Taguchi method using Grey Relational Analysis. ANOVA technique was further employed to know the optimal parameters from grey relational grade. The present study is to maximize thermal conductivity and coating thickness characteristics of electroless copper coated graphite, by optimizing the four coating parameters viz. composition of zinc, copper sulphate, graphite and sensitization time. Microstructural aspects were studied through SEM analysis.

Ulhas K. Annigeri, Raghavendra Ravikiran K., and Y. P. Deepthi, “Design and development of progressive tool for manufacturing washer”, AIP Conference Proceedings, vol. 1859. American Institute of Physics Inc., 2017.[Abstract]

In a progressive tool the raw material is worked at different station to finally fabricate the component. A progressive tool is a lucrative tool for mass production of components. A lot of automobile and other transport industries develop progressive tool for the production of components. The design of tool involves lot of planning and the same amount of skill of process planning is required in the fabrication of the tool. The design also involves use of thumb rules and standard elements as per experience gained in practice. Manufacturing the press tool is a laborious task as special jigs and fixtures have to be designed for the purpose. Assembly of all the press tool elements is another task where use of accurate measuring instruments for alignment of various tool elements is important. In the present study, design and fabrication of progressive press tool for production of washer has been developed and the press tool has been tried out on a mechanical type of press. The components produced are to dimensions.

<p>This paper presents the overall picture of the processes happening in printing industry. This research is aimed to improve the plant layout of existing plant. The travel time was reduced by relocating machinery. Relocation is based on systematic layout planning (SLP). The complete process of raw material entering the industry to dispatching of finished product is shown in 3-D Flow diagram. The process happening in each floor explained in detail using Flow Process chart. Travel time is reduced by 25% after modifying existing plant layout. © 2017 Author(s).</p>

Raghavendra Ravikiran K., Y. P. Deepthi, and Prakash, M., “Performance test of cryogenically treated and coated tungsten carbide cutting inserts”, in international conference on mechanical and manufacturing engineering(ICMME) , organized by the department of mechanical engineering, SCSVMV university, 2015.[Abstract]

Production cost is dependent on the life of the Tool. Because of enormous heat generation during the material removal process, life of the tool decreases. Tool life will be enhanced by cryogenic treatment which minimises the temperature at tool tip interface. Taguchi technique was employed to get optimum number of experiments for turning white cast iron after the cryogenic treatment and before cryogenic treatment. The correlation between four main factors such as speed, feed, depth of cut, tool condition and responses such as surface roughness, tool tip temperature were analysed. Mathematical model was formulated for tool tip temperature, and surface roughness. The error for the mathematically formulated model was observed to be less than 5%.The present work indicates that cryogenically treated tool have better surface finish . From the anova analysis it is inferred that tool tip temperature and surface roughness substantially reduced while using cryogenically treated tool. It was observed that cutting forces was more influenced by cutting speed of the tool followed by tool condition. Hardness of the tool insert showed improvement because of coatings.
