Essays on Computer-Aided Design

Rapid prototyping is the most convenient way to get a replica of a three-dimensional design CAD-generated 3D application way.

These physical models can be only aesthetic and useful for the study of the potential market of the product, or they may meet some or most of the mechanical requirements which would have the final piece, offering, in this case, the possibility to perform functional tests and approval before there even preliminary molds. That man made his hands the means that would shape the objects that determine their evolution, devised object, the object designed: tools, utensils, art, and beauty, among others. Use of science was done to create the elements that should give matter and harmony with their creations. ...

Historical origin and development of shipyard in Istanbul

Ships and shipyards are a very old tradition in Istanbul (Cvikel & Kahanov, 2013). The pioneer shipyard was designed in 1390. The shipyards developed quickly and as early as the 16th century, Turkish shipyards were leading globally (Grant, 2005). Traditional shipbuilding techniques in combination with modern technology have helped the shipbuilding industry develop as an international recognized trademark in shipping industry since the beginning of 1990's. In Istanbul, shipyards perform various functions ranging from creating a variety of ship models such as yacht both big and small. Repair and maintenance of the different vessels are also done in these shipyards. ...

The fashion process is the gateway to understanding the human realm. In my experience, I have come to appreciate the benefits of using clear approaches in the materialization of concepts. Fashion would be quite meaningless if designers failed to handle it systematically. A close look at significant fashion icons shows the extent which process can vitalize clothing concepts. For example, Wales Bonner’s ideas follow a consistent pattern. Her creations are characterized by a strict adherence to particular themes. Arguably, she can be described as a revolutionary fashion warrior. This is owed to the significant leaps she has made ...

Defining Concept of Design Thinking

Introduction The business world is very competitive such that it requires great minds, innovators, go-getters and great achievers who can tap into any given opportunity and make good use of it for success purposes. Success in today's competitive and technologically advanced world requires skills that are up to the task of handling the dynamic trends in the business market. These skills are numerous and vary in different firms and amongst these skills is design thinking (O’Kane, 2014). The business market requires vigilance in taking actions in an event of dissatisfaction and taking a course of action that is ...

Most of the computer aided design programs that are used today in drafting may seem new to many people even though they have been in use for more than a decade. These programs trace their origin to about 50 years ago. The modern technology designs and drafting are viewed as a result of the sixteenth and seventeenth century development of the descriptive geometry. Most of the work aimed at developing computer aided drafting intensified in the post war era, with many people working at MIT on the numerical control of machine tools and automating drafting and designing. During the 1950s, ...

Computer aided design has grown to be widely used in the field of engineering.It has come to replace the era when the design of any engineering component was drawn on paper; when engineers would walk around with rulers and tedious drawing materials just to come up with a simple design. The situation is, however, different with the coming of computer aided design. In the field of electronics,CAD has been used to develop the design and prototype,not only a single component, but also the entire circuit. The IC for instance, is one of the states of the earth developments that ...

- Abstract - Construction is an essential factor in the progress of the human civilization. It is in the construction industry that our infrastructure depends upon. The construction life cycle has several phases in it, one of these phases is the design phase. Before the advancement in computing technology - the invention of modern computers - construction engineers do manual designs; that is, through pencil and paper. This method of designing has become unfit as larger more complicated infrastructures and engineering designs develop. Hence, the need for a tool that will help construction engineers in the design phase. On ...

Abstract

Rapid prototyping describes techniques that designers employ in order to fabricate models of a physical product using computer aided design in three dimensions. . Rapid prototyping allows the designer to bind one layer of material to another layer using computer aided design on three dimensional frame. This report describes rapid prototyping techniques as applied in a case study. The report will pay attention to the prototyping technology used, the materials used in producing a prototype and the accuracy of the models that are produced using the rapid prototyping technology in question. One of the most prominent of these techniques is stereolithography. Since the ...

Computer Numerical Control

Computer Numerical Control (CNC), initially known as Numerical Control (NC), is the process of automating operations of a manufacturing machine depending on coding of letters, numbers and special characters. It involves the operation of conceptually programmed commands on a storage medium. It uses computers on a very large scale of the control where a set of coded commands or instructions are used to execute operation. The instructions are referred to as programs which are translated into electrical signals for input to motors that run the machines (Hauth 2011). The process of creating programs using numerical control is known as computer aided programming. This ...

Abstract

Lathes are being used since a long period of time and tooling and designing method, and the purposes for which it has been used most of the times are drilling and boring holes that are usually conical or cylindrical in shape. The manual lathe usage primarily depends upon the machinist and the experience in the designing field. With time there has been a major improvement in the efficiency and quality of part development, which is a result of numerical control into the process of tool designing and the use of lathe. The most advanced and the latest technique in this area is ...

THEORETICAL STUDY PROJECT The use of computers is widely gaining popularity because of its ability to make complex tasks achievable in the most effective and efficient manner. An architect firm can utilize several computer hardware and software for their day to day running of activities. There have recently been the development of many computer applications; top among them is the computer Aided design and Drawing (CADD) which aid the architects to create architectural designs and drawings, simulations, 3D modeling and production of blue prints (William 1993). Since there are several applications of computers in an architectural firm, ...
