Sheet metal forming is widely used in automotive and aerospace industry. In this paper analysis of sheet metal forming process by deep drawing was discussed. Static analysis on the deep drawing ...operation was carried out to find the stresses, strains and total deformation of deep drawing cup. CAD models are generated using CATIA from the dimensions obtained by theoretical calculations and analysis is carried out using ANSYS software. The force required to develop the cup, deformation and defect like tearing, wrinkles etc. can be obtained through simulation. By using this method it is easy to make stress and strain analysis for different materials. From the analysis, it is observed that Titanium has the maximum stress with standing ability when compared to copper and Aluminum.

Sand casting method is used to produce many useful products for many applications. The aim of the study is to manufacture a product with excellent dimensional geometry is achieved in sand casting ...process at low cost. We would expect manuscripts to show how design and/or manufacturing problems have been solved using computer modeling, simulation and analysis. In this work, the important mechanical properties of hardness and surface roughness are investigated on Aluminum 6063 cast material with and without incorporating the copper tubes as a vent hole in sand casting process. Since copper has high thermal conductivity when compared to other metals, the heat transfer rate will be varying from existing system. The copper tubes have made different diameters of holes on outer surfaces with selective distance of intervals. The specific number of copper tubes with various diameters are designed by CATIA modeling software and analyzed with Taguchi Design of Experiment. Taguchi L9 orthogonal array is used proficiently in the optimal value of hardness and surface roughness. The results are revealed that the maximum hardness value of 104 BHN is attained for 10mm distance of holes made on copper tube with an angle of 90o degree. The minimum surface roughness of 2.11 micron is achieved for 20mm distance of holes made on copper tube with 45o of angle as a vent hole in sand casting process.
A seed sowing machine is a valuable agricultural device that facilitates the precise and efficient sowing of seeds in fields. When designing and optimizing such a machine, several crucial factors ...need consideration including seed size, seed rate, soil type, and field conditions. The primary objective is to achieve uniform seed distribution and optimal seed-to-soil contact, which can be accomplished by incorporating a seed metering mechanism to control the seed rate accurately. Versatility is another important aspect of the machine's design, as it should be able to handle different seed sizes, types, soil conditions, and field variations. To achieve this, utilizing advanced technologies such as sensors, automation, and precision farming techniques can significantly enhance the machine's performance and efficiency while also reducing costs and minimizing environmental impact. The optimization of a seed sowing machine plays a crucial role in ensuring successful crop production. By implementing cutting-edge technologies and precision farming techniques, farmers can increase their yields and decrease the amount of seed and fertilizer needed for a specific area. Ultimately, this leads to improved productivity, increased profitability, and a more sustainable approach to agriculture.
The intensifying global distress towards the environmental problems and however, the demand for more versatile polymer-based materials has raised concerns about polymer composites containing natural ...organic fillers, i.e. fillers derived from renewable sources and biodegradable. The composites, which are often referred to as “green,” can be used in a variety of ways. Green composites are commonly listed as having possible applications in the automotive and construction industries, but an analysis of these applications shows that they are frequently an inappropriate fit for green composites' specific material properties. A concise summary of green composites is given, along with graphical comparisons of their relative benefits. In the present study flexural stress is calculated by using CATIA V5, AGMA and ANSYS. Designing a product is an important industrial activity that affects the quality of product, so because of this three dimensional objects is created, analysed and comparison among the three materials according to ASTM D 790 standard using modelling software CATIA V5. Coconut fiber reinforced with epoxy resin composite will have more life and durable because of its less deformation and high stress bearing capacity.

On the basis of milling process simulation, the software generates the manufacturing program for the NC machine tool.
Abstract
In mechanical design and manufacture, the minimum size of raw material of each part should be measured before processing. Generally, this size could be equal to the size of minimum bounding ...box. When the assembled parts of a product reach an enormous quantity, the measurement would be a rough work. This paper introduced an automated solving algorithm for the oriented bounding box based on principal axis of inertia, combined with CATIA structural tree recursive traversal algorithm according to CAA V5 Automation API, to implement an automated solution of the engineering acceptable minimum oriented bounding box of CATIA model.
Automating the tasks that require manpower has been considered as an area of active research in science and technology. Challenges in designing such systems include accuracy in the parameters of ...performance, minimal hardware, cost-efficiency, and security. The efficiency of drones designed for replacing humans is often evaluated using their weight, flying time, and power consumption. Herein, the prototypebased Drone model has been designed and discussed for horticulture applications. In this model, a horticulture drone has been designed for structuring and cutting of plants in street interstates. This methodology focuses on automation engineering that is utilized for cutting the plants in less time and less power, thereby diminishing the contamination that may happen by utilizing fuels. The epic part of this plan includes the less weight drone predesigned using Computer-Aided Three-Dimensional Interactive Application (CATIA) V5 Software. The throttle for the motors is adjusted at 50% to get the required thrust for the Unmanned Aerial Vehicle (UAV) to fly. Experimental results show that the horticulture drone has comparatively more flying time and less power consumption.
The Intake manifold is considered a crucial part of the IC engine as it increases engine efficiency and performance. This is achieved through the combustion of proper fuel-air mixture intake, which ...is dependent on the material geometry of the intake manifold.
The present work focuses on the geometrical modelling and structural analysis of the intake manifold followed by modal analysis. Static structural linear analysis was undertaken to check the structural safety using Finite Element Analysis (FEA) software. The static analysis results indicate that the equivalent stress of 426.38 MPa, maximum and minimum stress of 498.7, and 53.47 MPa, respectively were induced within the component. Whereas, a minimum deformation of 56.34 mm for a frequency of 977.45 Hz and maximum deformation of 104.22 mm at a higher frequency of 2518.1 Hz were observed by modal analysis. The above numerical modelling results indicate the vibration adequacy of the intake manifold structure.
