The A new Slip Line Theory For Orthogonal Cutting Mech Paper Presentation is about the orthogonal cutting suggested by Timae which is the formation of chip model with single shear plane. Merchant and Zvorykin have used the model problems including less force and energy and single shear plane.

 The Palmer and Oxley had utilized technique of cinema and material particles in the deformation zone. They have utilized Henky and balance moment equations. The important problem used in this concept is stress distribution and it is essential to create an assumption on balance force equations. Lee and Shaffer first suggested the plastic deformation.

 The experiment is caused in many methods to measure stress. Zorev and Bobrov have utilized concept of split-tool. It is based on built-up-edge formation and agglutination among tool parts. Gordon altered split-tool design dynamometer to reduce the influenced forces. Bagchi and Wright had used photo-elastic sapphire tool which decreases the errors of split-tool method.

 Friction and normal stress distribution uses classical theory of plasticity. The tool chip is precise between analytical methods to express the parameter. The theoretical and experimental distribution presents good model to the actual conditions. Based on stress distribution, the formula is predicted for forces.

Conclusion:

It is concluded that imaginary shear line agrees with the trajectory principle. This present data deals about important deformation zone, stress distribution, tool-chip contact length, and evidence of the model. The experimental research should validate speed of force. The stress distribution is used like an analysis of tool crater wear, temperature phenomena area, and tool strength determination.

The electronic signaling came into existence in 1950s which took the place of large connections of mechanical and hydraulic by electric components. In 1972, the first aircraft, fly-by-wire was changed electronically. The project is about digital aircraft FLY BY WIRE.

 Fly-By-Wire system was drafted such that the pilot is able to manage the controls with the help of inputs of the electrical by a computer system. The computer utilizes the data taken from other inputs and hence calculates the changes of the proper control. The command is sent to an actuator, wing or tail by WIRE system that manages the surface of the controls.

 The control systems of the digital system admit computers of aircraft to do in the absence of input. This method of operation can be seen in automatic stability systems. Gyroscopes are connected by sensors which are climbed in an aircraft to detect the manipulation in the motions in the roll, pitch, and yaw axes from level flight to straight flight.

 There are two kinds of FBW introduced into this project. They are analog system and digital system. Hydromechanical or electromechanical flight control systems are taken place by the FBW. The control mechanisms controls signal transducers and creates the commands electronically.

 Conclusion:

 Hence the Fly-by-wireless-Power-by-wire-Fly-by-optics-Mechanical-Seminar project concludes that the fly-by-wire refers to a configured computer that manages and system interrupted among the final control actuators and the operator and it admits the computers of aircraft to do actions in the absence of input of the pilot. The pilot input is done manually based on the control parameters.

This Influence of Shape of Directrix on the Cost of RC Cylindrical and Conoidal Shells Mechanical Engineering project & Seminar Topic is based on the Cylindrical and Conoidal shells. There are few kinds of cylindrical and conoidal shell. They are Circular Directrix, Parabolic Directrix, Inverted catenary Directrix, and Cycloidal Directrix.

 Shells space roofs are made for plane roofs because these roods cover major floor spaces and utilizes construction materials. The curved space roofs need materials of about 25 to 40% rather than plane elements. The shell roofs are major one because cross section is stressed with direct forces and bending effects. Based on this, shells thickness is very less ranging between 75mm to 150mm.

 The shell structures are very costly. Economically, thin shell roofs are competitive with many same units. The form works cost builds shell roofs costly rather than cement and steel. The costs of form work are made based on precasting mobile forms. The benefits of shell roofs are aesthetically superior, material used is very less, form work is deleted in the starting, and high column free areas are covered.

 Cylindrical shells are the shell structures due to span up to 45m with less material need. They are important structures since it is made by arch forms to remove thicknesses and stresses in the transverse way. The conoid surface is created with movement of straight parallel to a rigid plane.

 Conclusion:

 The project concludes on the shell roofs which are used for sport auditorium, exhibition halls, hangers, industrial buildings and many span structures. The roofs are very costly and utilized for domes by Romans. The advances like the shell structures make use of prefabricated shell elements.
