Titanium (Ti) has been widely used in many fields such as aerospace, automotive, engineering and medical. The main properties of Ti are high strength, low density, and excellent corrosion resistance influence their value. These properties make them very attractive for a variety of applications. Ti alloys provide structural materials in the aeronautics and astronautics industries because of their high specific strength but they are expensive. Stainless steel is a widely used and it is an inexpensive
The purpose of creating human criticized robotic arm is to replace human is hazardous task such as welding, painting or deal with chemicals in lab. The following present several research done in the field of robotics Vibration-free position control for a 2 DOF flexible-beam studied by [5] whose aim to control the end of the flexible-beam by decreasing the vibration when the beam is subject to move. They
industry, and ultimately led me on the path to become a Mechanical Engineer. My efforts to improve my technical knowledge and analytical skills met with encouragement and motivation to further pursue this field. The organized curriculum of the University of Pune provided me with a constructive research and technical exposure in
CHAPTER 1:- INTRODUCTION 1.1 (A) Problem Summary The service environment of fossil-fired boilers along with human errors during engineering, fabrication, construction, operation, and maintenance will always result in occasional boiler tube failures (BTF). The industry goal is for a forced outage rate less than 1.5% with zero chemistry related failures. The frequency of these failures depends on the corrective actions taken to prevent or reduce boiler tube damage. Repeat BTF usually result in frequent
surfaces if the pattern to facilitates removal from the die. Making a pattern using wax or some other material that can be melted away makes the mould. Pattern may be made in loose pieces and then welded together by means of the hot wire resistance welding iron to form the complete pattern. The numbers of patterns are welded together along with the common gating system. 1.2 CLASSIFICATION OF RAPID PROTOTYPING TECHNOLOGY. Technological advancement and globalisation resulted in increased competition
finish by heating the food as follows. The AC voltage 220v is applied after then rectified to DC and then subsequently back to a high frequency AC source through an inverter. This high frequency current creates a high frequency alternating magnetic field through an induction coil. Therefore, placing a cooking pan below the induction coil will induce eddy current in the pan. As a result of which, heat energy will be produced on the surface of the pan. The internal resistance of the pan causes heat to
discovered in 1751, by Axel Fredrik in Sweden. It belongs to the transition metal group and is known for its hardness and ductility. Significant chemical reactivity is exhibited by pure Nickel. Nickel in its pure or low-alloy form is used in several fields as it is highly resistant to various reducing chemicals. Nickel when annealed exhibits low hardness with good ductility and malleability. 1.1.1. Nickel 200 1.1.1.1. Metallography Nickel 200 is a solid-solution alloy with a face-centered cubic structure
processing manufacturing, but by using additive processes. In this way, each layer is deposited individually, respecting certain coordinates that lead to the wanted shape, described in the digital model. This technology has easily covered a wide area of fields, since the beginning of the current century, with the advance in the construction of the 3D printing machines, such as: industrial design, architecture, automotive, engineering and construction (AEC), dental and medical industries, geographic information
