This Mechanical Properties of Foods Btech Seminar deals with the concept ofdeformation of food and explains how force causes these deformations on food items and commodities, with several examples and calculations.

The Seminar first explains that force causes acceleration to a commodity and occurs due to  phenomena such as gravity, magnetism, or anything else that causes a mass to accelerate. It describes Deformation as a change in shape due to an applied forcewhich when  considered can measure the “firmness” of a commodity.  The stress and strain experienced by a body is represented in the form of graphs such as Bioyield point (BYP)  Microstructure vs. Macrostructure and it also calculates the linearity in steel,rubber and corn.The different forms of deformations are also discussed such as Length deformation, Compression, Tensile / stretch, Shear and Bulk compression.

The shear forces acting on bodies are determined using modulus of elasticity, elastic ity elements,shear modulus, buls modulus,poisson’s ratio and viscosity etc.The shear forces deforming different bodies are also explained.And these calculations and study help in determining how force causes deformations in food items.

CONCLUSION:

Thus the project on mechanical properties in food explains the causes and methods of deformation of food items under force and the experiments conducted in this project helps the food corporation in studying the logitivity of food items based on such criterias.

This CAD & CAM Mechanical Seminar designs a Computer-Aided Design(CAD) and Computer aided manufacturing (CAM) to make mass production of any product or component economicaly possible.

To meet the requirements of mass production, there is rapidly growing need for improved communication and feed back between the manufacturing and design process, integrating them into a single system capable of being optimized as a whole. The use of computer in manufacturing process is the answer to meet this requirement and objectives.

The project uses CAD/CAM technology which plays an important role in functioning of robots. In CAD/CAM system the robot work data is prepared from CAD data from the first designing process. This system is a kind of off-line teaching system. Since an actual robot is not used to input data for path creation, the coordinate system data must be corrected and simulations necessary before loading a created data.However,Robots are inevitable for application in the field where the work is extremely difficult or impossible for human being to perform.

The Bending Load Capacity Enhancement Using Asymmetric Tooth Profile aims at developing a new method to enhance the bending load capacity of gear tooth using Asymmetric Toothprofiles and thus improving the fatigue strength of the tooth by heat treatment or surface quality improvement.

Any power transmission devices operate in one direction, only one side of the tooth surfaces (the front oftooth) is in mesh. So the tooth is not necessary to be a symmetric form. Different standard pressure angles are used in the front and back profiles of an asymmetric tooth.

In this project, tooth root stress and bending stiffness of the asymmetrical tooth for several combinations of standard pressure angles were calculated by the use of finite element method. As gears are functional units used for transmission of power in transmission systems,fine module gears are used for low noise, vibration and for compact size of transmission system as the smaller gears will lead to insufficiency in bending load carrying capacity which is a serious problem in plastic and sintered gears.

CONCLUSION:

This project analyses  bending stress with the aid of FEM for asymmetric and symmetric tooth and has concluded that Asymmetric teeth have better performance than symmetric teeth for bending stress minimization.It has also found that as pressure angle on drive side increases, the bending stress decreases and bending load carrying capacity increases.The calculations were performed for not only the maximum stress but also the stress amplitude from fillet to tooth root considering the gearing procedure
