So it is required to find the optimum parameters in order to have easy and economical machining. Turning operation is most important in the machining process. Especially of hard materials it is difficult sometimes to do so. For better results, the selection of proper process parameters is very important. This dissertation work presents, the effect of process parameters on various materials while performing turning operation and been validated by various methodology techniques. It also highlights on the effect of input controllable parameters over the required output values. According to ISO 3685 design of experiment was carried out. Tool life was calculated according to different cutting speed and machining time keeping feed rate and depth of cut constant. Optimum values were obtained and the effect of cutting speed on tool life was studied. 2020-07-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/1340 Title: Evaluate the effect of process parameters on mechanical properties of 6mm thickness SS317L weld joint for receiver application GTAW welding Authors: Pandya, Prashant R. Abstract: GTAW welding is most important especially welding of stainless steel and aluminum are more difficult to do. Nowadays SS317L materiel is used in top production receiver application in chemical and Pharma Company. That’s why this must have contain good mechanical properties and also resistance to corrosion. For achieving the good mechanical properties of weld ment, the optimal selection of process parameters is very important. For the GTAW welding the most influence input parameter are selected form the ASME section IX. In this work, the effect of different welding parameters like gas flow rate, current and included angle is selected for the project work. The filler wire which is used for the project work that is ER317L for similar welding of SS317L 6mm thickness plate joint. Tensile test and hardness test is done for check the mechanical properties of weld joint respectively. ANOVA is used for finding out the most influencing input parameter on output result. Optimization of selected parameter done by response surface optimizer. After the optimization validate the result obtain. Taguchi L9 orthogonal array in DOE is used for the optimization with MINITAB 17 version is used. 2020-07-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/1339 Title: Investigation on the effect of alloying elements addition and solidification time on nodularity on 400/15 SGI casting Authors: Thumar, Durgesh R. Abstract: A spheroidal graphite iron (SGI) is widely accepted material for the casting process. It is also known as graded casting and researcher claims that it is difficult to maintain the proportion of the elements and its composition. One of the ways to control it in the required way, the microstructural analysis is becomes necessity. The current research is addressing the impact of different alloying elements and mould opening time (self-annealing) of SG 400/15 grade cast iron. The general measures in term of microstructure analysis is nodularity, to maintain its required counts as per the specific application is depends on the alloying elements and solidification times and many other parameters. In SGI, nodularity is the strong function of the mechanical properties of the product. In the current research, the efforts have been made to establish a relationship between nodularity and proportion of alloying elements including magnesium, manganese, sulfur, silicon and other important process parameters i.e. pouring temperature, pouring time and mould opening time. 2020-07-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/1338 Title: Development & Experimental Evaluation of ABS C type Hook Manufacture using FDM technique Authors: Makwana, Niraj P. Abstract: Fused Deposition Modelling (FDM) is an extrusion-based modern technology that is becoming increasingly popular because it allows manufacturers to produce difficult components immediately from computer-aided design (CAD) models. For the industries like automotive, aerospace, and die & mould, etc., it is necessary to investigate the mechanical behaviour of 3D printed parts. FDM printed components' a competitor mechanical characteristics compared to injection moulded ones make functional application difficult. The complexity of process factors makes it difficult to forecast the mechanical behaviour of FDM printed components. Here, the issue at discussion is the mechanical characteristics of 3D- printed components. For modelling, Fusion 360 parametric is utilised, while ANSYS Workbench is used for analysis. The lateral movement of a C Type Hook is calculated conceptually, and for validation, the practical results are compared to those from static structural analysis. The research's main topic of investigation is the effect of varied Infill densities in C Type Hooks. Five levels of infill density (10%, 20%, 30%, 40%, and 100%) honeycomb structure are evaluated mechanically to acquire tensile abilities when utilising ABS material in real-world scenarios. Further work was done to investigate different tensile mode characteristics for an FDM manufactured Infill pattern. Results from both the practical and analytical bases are compared in this work. 2023-06-01T00:00:00Z
