What Is Computer Aided Manufacturing?

Over the past decade, manufacturing processes all over the world have undergone some dramatic changes. The introduction of automated systems and computer technology has allowed industries to significantly increase their productivity. CAM is the abbreviation for Computer Aided Manufacturing. Computer aided manufacturing accurately converts product drawing or the object into a computer readable code format, enabling the machine to manufacture the product. Computer aided manufacturing can be used in different machines like lathes and milling machines for manufacturing the related product.

A computer aided manufacturing system allows the manufacturer to systematically communicate work instructions to the machine. CAM has evolved from a technology referred to as the Computer Numerical Control (CNC), invented in the 1950s. CNC performed a set of coded instructions in a punched paper tape.

Computer aided manufacturing facilitates effortless and quick computer programming and faster execution of design changes. The computer aided management system integrates the computer aided design systems and controls tasks that involve order placement, scheduling, and replacement of tools. The implementation of CAM system leads to overall increase in efficiency of the manufacturing process. CAM systems are used in the automotive, aviation and furniture manufacturing sectors and areas such as mechanical engineering and electronic designing. Another significant benefit of using the computer aided management system is that it allows customization of the manufacturing process for creating client specific designs.

A computer aided manufacturing system requires a 3D environment for making it compliant with CAD systems. The CAM system can cost $18,000 or more along with the appropriate software. CAM allows automated integration of the manufacturing procedure with other mechanization systems such as Computer-Integrated Manufacturing (CIM), Integrated Computer-Aided Manufacturing (ICAM), Flexible Manufacturing System (FMS), Direct Numerical Control (DNC), and Manufacturing Process Management (MPM).
Repetitive tasks involved in the manufacturing process are delegated to machines using the CAM system, allowing workers involved to concentrate on quality control and productivity.

How Has Computer Aided Drafting (CAD) Revolutionized Engineering Industry?

CAD, Computer Aided Design has brought about a technical revolution in the Engineering Industry. CAD Services can be classified into broad categories like Architectural Services, Structural Services, MEP and Mechanical Services. CAD for Engineers and Architects today is like Oxygen for the living. Cad Services is a boon for all companies' worldwide who would like to execute CAD projects with minimum cost and quick deliverable capacity. With the consistently growing demands in construction industry and CAD services have achieved eminence across the globe. This technology has contributed immensely in development of Construction Industry, Building and Infrastructure development, Green Building concept along with other Engineering Domains like Machine Designing, Aeronautical sheets, Transformer designing, GIS, Pressure vessel designing etc.. Engineering industry today uses CAD Services to ensure Less cost, best quality, quick turnaround time along with excellent project efficiency. CAD is no longer limited to AutoCAD. There has been a great evolution in the CAD Software too.CAD professionals globally use software which is helpful in are using latest software like AutoCAD, Revit, 3D Studio Max, Pro-E, Solid Works, Inventor, MicroStation etc to execute Designing, Drafting and Modeling projects. With the help of such software, the entire project execution cycle has come to a new arena due to CAD Services. It is now possible to visualize an entire building and it's detail even before it is completed. This is possible with the help of "Virtual Construction Modeling" also referred to as Building Information Modeling in Engineering Industry. 3D Rendering makes it possible to give any building or product a photorealistic feel before the actual construction or manufacturing of a product. This development has also caused increase in companies providing Engineering and CAD Services. With transformation of blue prints created manually to digitization of CAD Drawings, many opportunities have opened up for Architects, Engineers and Drafters.

CAD services assure absolute digitization of manual drawings to computerized drawings via scanned pdfs, hand-drawn sketches or old manual drawings. Companies are using different approaches and techniques to take utmost advantage in terms of project execution. As mentioned earlier, CAD Services are no longer limited to one particular domain or segment. Arrays of services are covered under one umbrella. Besides project execution, computerized CAD Drawings or Images are easier to maintain, save or send across to clients. There is no risk of images or drawings being damaged in course of time. Errors can be rectified easily without taking much of time and can aid to quick turnaround. In software such as Revit, a change made in one part of the model reflects in the entire model by reducing manual intervention. This also facilitates definition and extraction of individual sheets or different part of drawings and every minute detail.

These are one of the main reasons that across the globe, major construction houses or Infrastructure companies are eminently outsourcing CAD Services. This process over a period helps companies gain advantage over their competitors who do not outsource their requirements. Cad Technology has evolved into a different era in a short span of time and is constantly evolving into giving better shape to the Engineering industry. CAD Services now helps CAD companies and professionals manage their Designing Drafting or Modeling projects more efficiently. Companies offering CAD Services and companies who are constantly upgrading their technical skills will always be in an advantageous position compared to companies who still rely on traditional methods of executing projects.

The Amazing Quad Core Computer

Let us discuss the two main quad core computers launched by Intel and AMD. Intel was the first one to launch this computer under the name of Kentsfield, which is also called Core 2 Extreme quad-core QX6700, and it is no less than 80% faster than Conroe or Core 2 Extreme X6800.

The chips of these quad core computers are based on the latest `Core` micro architecture technology. It is not just low powered but also gives high performance. But don`t be fooled into thinking that Kentsfield is a power-saving computer by any means.

This computer with a 2.66GHz chip having a 1066MHz front-side bus (FSB) is ideally suited for those users that require heavy or highly accurate scientific calculations. It is generally used in the fields of actuarial sciences, digital content creation, financial applications and engineering analysis, like CAD. The director of Intel`s operations for digital enterprise group, Mr. Steve Smith, has claimed that this quad core computer will be 58% faster for crating digital content system, and for video, digital audio and photo editing.

To talk in simple words, Kentsfield and other such computers are not meant for ordinary people`s desk. They are more suited for high-tech workstations and desktops. It will not be wise to think that the average customer who needs a computer for general applications like word, PowerPoint, games or internet and etc., will go for a complex, complicated and expensive computer like this. For these purposes, there are many other types of products made by Intel. Apart from this, as you must have guessed by now that this high-tech computer needs a lot of power and this feature makes it practically useless for people on the go. Perhaps it will take some more research and modifications before the quad core computer becomes popular as a laptop.

Intel has launched the mainstream and commercial version of these computers. This computer is known as Core 2 Quad Q6600. It runs at 2.4GHz and it is currently priced at around $210. This budget quad-core computer is estimated to have a somewhat smaller thermal envelope, and will be at 105 watts as compared to 130 watts of the Kentsfield Core 2 Extreme quad-core QX6700.

AMD`s Quad Core computer is built on a 65mn process. They are using a new technology called Silicon-on-Insulator process. It allows faster transistors that have lower power leakage to be easily used and this unique feature helps greatly in reducing wasted heat and power. For more energy saving, each core of this computer is allowed to run at entirely different speeds or can be turned off totally with the help of the new `Enhanced Power Now` feature. This computer is also packed with an enhanced `Crossbar Switch` that enables the users to access different parts of cores at the same time. Some other vital features include the integrated memory controller along with the latest `Direct Connect Architecture 2.0` that allows much faster `Hyper Transport` speeds.

Though these features can extract exclamations of wonder and happiness from any geek but the fact remains that for the average PC buyer, this still means Latin and Greek. Definitely many more core computers using this technology are on their way and will revolutionize the computer industry but it will be some time before people embrace this technology as a part and parcel of their life. Computer makers claim that within a few years the popularity of quad core computers will triple itself.

Architectural Rendering - Computer Aided Design (CAD)

You probably have heard about CAD rendering, and if you are not a graphics artist you may not be aware of just how often and in where it is used. It might surprise you just how often and in what applications CAD rendering appears.

Architectural rendering is not just for architects despite its name. Car manufacturers, landscapers, engineers and others use CAD rendering or have it done for them. It allows them to see flaws in design and perspective before costly errors are made in real time production.

Architectural rendering is very detailed oriented and incorporates realistic lighting and textures to give a much more realistic feel to the modeled object. Virtual walk-throughs can be created for the web to give prospective buyers a real feel for the design. Car designers are bringing their models to life in three dimensions before production with the aid of architectural rendering.

CAD or computer aided design can be as simple as a 2D representation with little detail or realism to as complex and versatile as 3D parametric solid modeling. It depends on the use the end product will be put to, as well as the skill of the CAD operator. The simplest are 2D or wire models.

There are many brands of CAD software available. They range in cost from freeware (high learning curves with low end simplistic results), all the way to high end software with sophisticated engines that can literally take a design from the drawing board and breathe life into it. Though, even the expensive software may also have high learning curves because of all the options and details that can be imported.

If you are a designer you may not necessarily be a software genius. CAD software takes quite a bit of skill and usually either schooling or hours upon hours of trial and error. Architectural rendering or CAD can be outsourced and sometimes this is the wisest choice in terms of time and expense.

Should the option of a rendering service appeal to your circumstances and very possibly to your budget, then it is important that you view samples of their work, inquire as to their delivery time, and balance costs. Make sure you choose a reliable service and beware any that promise too low a price or only offer stock rendering. Good services will get as much information as possible before giving a price beware of any that offer a custom architectural rendering service for a flat fee or the costs seem way too low. In the case of architectural rendering as with most things, you usually get what you pay for.

Should you decide to learn to use Architectural rendering software then set aside sufficient time for the learning curve. Invest time in finding tutorials that will shorten the learning time. Make sure your software is applicable for the use you want to put it through and lay in a good stock of patience.

Computer Graphic Visualization Technology Overview

Visualization, especially the development of Virtual Environments (VEs) make a significant impact on how construction project stakeholders can perceive and successfully complete their projects; sales, marketing and manage the properties.

The purposes of visualization general fall into two categories:

Improve the design or construction works
Make sell which either sell the design or sell the property

Most times, the different visualization purposes will affect how to get the visualization projects done. Understanding of visualization technology and workflow will make signification impact on the budget and how well the goal can be achieved.

This article will overview below major areas, but provide detail in separated articles.

About visualizations, there are:

Three major categories

Visualization (texture mapping, ray tracing, lighting and photo editing)
Animation/simulation (fly-by, walk-through)
Modeling (solid modeling, surface modeling, wireframe modeling)

Three major process steps

Content creation (3D modeling, texturing, animation)
Scene layout setup (lighting especially but also the creation of the surface or mesh)
Rendering (instant rendering and no instant rendering)
View flow and interactive system setup (this doesn't apply to the traditional static graphic)

Six major technologies

Static rendering: either 2D or 3D imagery. Photorealistic rendering needs high-end hardware, software and comprehensive library. It is foundation of following solutions.
Animated images: multiple static images are put together and show the images in sequence automatically. Such as via GIF image or scripted web pages, etc.
360/720 degree virtual view: view the space or item in 360 degree freely with limited zoom in and zoom out. Single viewpoint. Can be delivered in Flash, QuickTime or other scripted computer language.
Animation: images are display smooth move at 24 to 30 frame per second. Such as via Flash, QuickTime, Windows Media files, etc. The route either pre-setup or have single viewpoint. It also knows as fly through.
Virtual Reality or Interactive virtual model: It is simulated 3D virtual environment which user can interactive with. This technique is invaluable to modern architects, engineers, real estate developers, facility manager and marketing professionals as it allows them to simulate most scenarios that they will encounter during the design, construction, and eventually the life of the structure they are attempting to build, manage and sale. Virtual reality allows the project team members to essentially create their structures and test them without wasting any of the resources necessary to complete the structure in reality. For the marketing, sale professionals and potential buyer, they sale and explore every possible units, layout, appliance, material, color, textures options long before the model unit available.
Mixed Reality: It combine real and virtual world to create a new environment which real and virtual world co-exist and interactive in real time. The real world can be still picture or steam live video via locally or remotely camera. Mixed Reality brings the interaction and virtual world to another level.

Three styles

Photorealistic
Non Photorealistic
Non rendered computer graphic

Five major delivery structures

Standalone file
Interactive CD
Client - server structure
Browser -server structure
