The Future of CADCAM Assignment - Essay Example It was in the 1950's that the Numerically-Controlled machines were based upon the technology of paper tapes which had proper spaced holes punched into the papers. it is similar to the paper roll which makes piano works having only an inch width which is used to feed the numbers into controller machines. These are wired to join the motors positioning work over the machine tools. These controllers are electro mechanical that allows easy incorporation of the digital technologies in their original form. During the period of late 1960's these Numerically-Controlled machining centers were very easily available for the commercial incorporation of a variety of machining processes, and also enabling the automatic tool changing process. So these tools were capable of performing any work on the many faces of any kind of work further enabling the movement of the work piece to the specified positions which were previously programmed. This programming was done making use of a variety of automatic tools. Thus making it possible to do the same piece of work over and over, automatically with perfection and very little human input. The NC was immediately automated giving a newer level of manufacturing. The incorporation of feedback loops was also done. The development of APT was a breakthrough in the success of the NC technology which is a universal NC programming language. The Automatically Programmed Tools developed in1962, enables the programmers to develop the postprocessors, tailored to each type of NC tool. This helped in the output sharing between different units having different manufacturing capabilities. CAD and CAM Together now: CAD basically uses the software known as TTUA (http://en.wikipedia.org/wiki/CAD/CAM). It assists engineers, architects, designers in their activities. This geometrical tool in the Product Lifecycle Management (PLM) also involves a special hardware. These tools are used and incorporated in almost every sector like manufacturing, designing, planning etc using the tools CIM, CAPP, FMS, and JIT etc. The development of Computer-aided design had its effect on the NC technology due to the differences in the formats of various files which were used initially by the drawing and manufacturing programs. " in the CAD world, we take a pencil out of the hand of the operator and place it into the hand of the computer" (Jan Bone,1994). With the newer and variety of CAD applications like Solid Works and Auto Cad and CAM applications like Master Cam, both designing and manufacturing sectors now use these variety of CAD/CAM software. Most of the CAD/CAM software are used more by architects these days, along with product designing and manufacturing. Future trends in CAD/CAM: Though the current CAD/CAM applications are much user friendly and satisfactory, and people do not think there is nay need for advances in the same, but the coming decade will have many advances in techniques and implementation of CAD/CAM, for the creation and manipulation of the work piece geometry. The standards for its applications will give more flexibility to its users in the interfaces, data transfer, computer designing and architecture etc. thus it can be said that these future developments will have a solid impact on both, the numerical control system and the manufacturing applications. By anticipating the basic questions like what is the direction of NC and CAD/CAM What are the

Smoking Cigarettes is Good for Your Health - Article Analysis Essay

Smoking Cigarettes is Good for Your Health - Article Analysis - Essay Example From the article, it is evident that the writer believes the only way to realize communication and draw the attention of readers is through taking this risk. Readers like reading stories that are the opposite of expectations. Although writers take the risk to explore a topic not previously done, they eventually bring new and viable ideas into the book. In writing to win a large number of readers, safety in writing is a risk that many writers overlook. Scholars have considered safety as a component with less weight in the art of writing (Tepper). Many people know that smoking is dangerous to one’s health to appoint that the cigarettes contain a warning of being harmful. However, the author brings a different idea to book, where he several advantages of smoking unlike what other writers do. In this case, it is risky for the author to choose such a sensitive topic and argue of benefits of smoking knowing very well that security agents are opposed to the idea. This means that the writer can be questioned by authorities hence risky to him. The idea that cigarettes are beneficial to humankind raises eyebrows and hence can rise the contest on the subject. Partiality in writing is most likely to increase the controversy and hence risks in writing. In whatever subject matter, the writer must argue on both sides. This means that the advantages and disadvantages must be well presented in the article. The author of the article analyses several disadvantages of smoking despite the fact that they are for the idea that smoking is health to one’s life. In an argumentative writing, the author must present both sides and show the strengths of each without been bias on one side., this means that the author should not take a side on whatever argument and should just make suggestions remaining partial at the end of the writing. Although the author tried to make a justification that smoking is healthy, disadvantaged of smoking are keenly presented in the article showin g the impartiality of the author. The difference in the presentation of ideas is from the diverse differences in both written and oral languages. With the growth of technology witnesses in the last past decades, language has moved from verbal to written. Every cultural setting has its norms regarding language and manner of presentations. As such, there is a classification of languages from standard, regional and local languages. Writers majorly concentrate with standard language. In the article, there is a proper use of standard language that is easily understood. Standard language goes hand in hand with the controversial topic (Ferraro). From this, the readers expect more of the article as they would when reading a normal scholarly article. To ensure that the author convinces the readers, facts and opinions are given and required evidence provided.
