Pro-ENGINEER

                             An Overview of Pro/ENGINEER


The Foundation of Pro/ENGINEER

What is Pro/ENGINEER?

                    Pro/ENGINEER is a computer graphics system for modeling various mechanical designs and for performing related design and manufacturing operations.
                The system uses a 3D solid modeling system as the core, and applies the feature-based, parametric modeling method.In short, Pro/ENGINEER is a feature-based, parametric solid modeling system with many extended design and manufacturing applications.

How is Pro/ENGINEER different from other CAD systems?

            Pro/ENGINEER was the first CAD system entirely based upon feature-based design and parametric modeling. Today most software producers have recognized the advantage of this approach and shifted their product onto this platform. Nevertheless, the differences between a feature-based, parametric solid modeling CAD system, and a conventional CAD system include


Ease of Use:

• Pro/ENGINEER was designed to begin where the design engineer begins with features and design criteria, through cascading menus. 

• Expert users employ "map keys" to combine frequently used commands along with customized menus to exponentially increase their speed in use. 

• Pro/ENGINEER provides the ability to sketch directly on the solid model, feature placement is thus simple and accurate. 

Full Associativity: Pro/ENGINEER is based on a single data structure, with the

ability to make change built into the system. Therefore, when a change is made anywhere in the development process, it is propagated throughout the entire design-through-manufacturing process.

Parametric, Feature-Based Modeling:

• Pro/ENGINEER's features features contain non-geometric information, such as manufacturing processes and associated costs, as well as information about location and relationships. 

• This means that features do not require coordinate systems for placement, and they "know" how they are related to the rest of the model. As a result, changes are made quickly and always adhere to the original design intent. 

Powerful Assembly Capabilities:

• Assembling components is easy with Pro/ENGINEER Simply tell the system to 

"mate," "insert," or "align" the components. They are assembled, always maintaining the design intent. 

• Components "know" how they are related, so if one changes, either positionally or geometrically, the other will change accordingly. Parts can be designed right in the assembly and defined by other components, so if they move or change size, the part will automatically update to reflect the change. 

Robustness: The Pro/ENGINEER family of products is based on a double precision, non-faceted solid modeling core. This provides the engineer with the most accurate representation of geometry, mass properties, and interference checking available.

Change Management: Powerful change capabilities are inherent with Pro/ENGlNEER full associativity, enabling design-through-manufacturing disciplines to execute their functions in parallel.

Hardware Independence:

• Pro/ENGINEER runs on all of the major UNIX and Windows platforms, maintaining the same look and feel on every system. 

• Users can select the most economical hardware configuration for their needs, and mix and match any -combination of platforms.

PATTERNS

PATTERNS:              From the design, provided by an engineer or designer, a skilled pattern maker builds a pattern of the object to be produced, using wood, metal, or plastic; other materials to be used can be polystyrene or even sand strickled into shape. The metal to be cast will contract during solidification, and this may be non-uniform due to uneven cooling. Therefore, the pattern must be slightly larger than the finished product, a difference known as contraction allowance. Pattern-makers are able to produce suitable patterns using ‘contraction rules’. Different scaled rules are used for different metals because different metals/alloys contract at different rates. Patterns also have core prints; these create registers within the moulds, into which are placed sand cores. Sand cores are used to create undercut profiles and holes which cannot be moulded.                  Paths for the entrance of...

Mechanical behavior of Al-Sic-Zn-Cu Metal Matrix Composite

                     Aluminum is the world‘s most abundant metal and is the third most common element, comprising 8% of the earth’s crust. The versatility of aluminum makes it the most widely used metal after steel. After iron, aluminum is now the second most widely used metal in the world. This is because aluminum has a unique combination of attractive properties. Low weight, high strength, superior malleability, easy machining, excellent corrosion resistance and good thermal and electrical conductivity are amongst aluminum’s most important properties. Aluminum is also very easy to recycle. A unique combination of properties makes aluminum and its alloys one of the most versatile engineering and construction material available today. A metal matrix composite (MMC) is composite material with at least two constituent parts, one being a metal. MMCs are made by dispersing a reinforcing material into a metal matrix. The matrix is the ...
