DXF is an acronym for Drawing Exchange Format . It was created solely by Autodesk to provide a method of exchanging drawing file information in a generic language which they could control without having to give out their own proprietary format. Unlike IGES, DXF was not designed as a universal language by a committee or by multiple software companies.
CADL is an acronym for Cadkey Advance Development Language . It was developed by Cadkey Corporation and it is commonly used as a method of exchanging drawing file information. CADL is a text file with one or more lines defining geometric entities.
6. What is Reverse Engineering?
Engineering is the profession involved in designing, manufacturing, constructing, and maintaining of products, systems, and structures. At a higher level, there are two types of engineering - Forward Engineering and Reverse Engineering.
a. Forward engineering is the traditional process of moving from high-level abstractions and logical designs to the physical implementation of a system. In some situations, there may be a physical part without any technical details, such as drawings, bills-of-material, or without engineering data, such as thermal and electrical properties.
b. The process of duplicating an existing component, subassembly, or product, without the aid of drawings, documentation, or computer model is known as reverse engineering.
Following are reasons for reverse engineering a part or product:
• The original manufacturer of a product no longer produces a product.
• There is inadequate documentation of the original design.
• The original manufacturer no longer exists, but a customer needs the product.
• The original design documentation has been lost or never existed.
• Some bad features of a product need to be designed out. For example, excessive wear might indicate where a product should be improved.
• To strengthen the good features of a product based on long-term usage of the product.
• To analyse the good and bad features of competitor's product.
• To explore new avenues to improve product performance and features.
• To gain competitive benchmarking methods to understand competitor's products and develop better products.
• The original CAD model is not sufficient to support modifications or current manufacturing methods.
• The original supplier is unable or unwilling to provide additional parts.
• The original equipment manufacturers are either unwilling or unable to supply replacement parts, or demand inflated costs for sole-source parts.
• To update obsolete materials or antiquated manufacturing processes with more current, less-expensive technologies.
7. What is "Value Engineering”?
Value Engineering (VE) is the systematic application of recognized techniques used by a multi-disciplined team to identify the function of a product or service, establish a worth for that function, generate alternatives through the use of creative thinking, and provide the needed functions to accomplish the original purpose of the project. This should be accomplished reliably and at the lowest life-cycle cost without sacrificing safety, necessary quality, and environmental attributes of the project.
8. What is the requirement for Rapid prototyping technology (RPT)?
Any of a variety of processes that avoid tooling time in producing prototypes or prototype parts and therefore allow (generally non-functioning) prototypes to be produced within hours or days rather than weeks. These prototypes are frequently used to test quickly the product product's technical feasibility or consumer interest. This involves conversion of Graphical Model (Stl file format) into Product prototype by using techniques like:
• Stereo lithography,
• Laser sintering.
9. Are you implementing FMEA in your product design?
We have framed our own procedures for Failure Mode and Effects Analysis . FMEA elements are identified or analyzed in the FMEA process. Common examples are Functions, Failure Modes, Occurrences, Risk factor, Causes, Effects, Controls, and Actions. In product design we implement FMEA process, based on the FMEA result we optimize the design.
• What is the scope for Pro/E?
Pro/E, which is the high end CAD/CAM/CAE software, is one of the world's most widely used software. Because of its power to capture the design intent of any complex model by incorporating intelligence into the design and its parametric feature based characteristic it becomes the fastest growing solid modeling software for mechanical design automation in the world.
• What is parametric modeling?
In a model, feature is the smallest building block. Integration of number of features builds the model. Parametric modeling means the features of a model become interrelated while drawing by taking reference of each other. Redefining the dimensions or the attributes of a feature will propagate automatically through the model. (This relationship is known as parent-child relationship).
• What is geometric tolerance?
In manufacturing, you can use geometric tolerances to specify the maximum allowable deviation from the exact size and shape specified by designers. You can create, modify, display, and delete geometric tolerances (gtols) in drawing mode.
Geometric tolerances provide a comprehensive method of specifying where on a part the critical surfaces are, how they relate to one another, and how the part should be inspected to determine if it is acceptable. When you store a Pro/ENGINEER geometric tolerance in a solid model, it contains parametric references to the geometry or feature it controls—its reference entity —and parametric references to reference datum's and axes. As a result, the system updates a gtol's display in the model.Example
• Why mold design is effective in Pro/E
In mold-design, parting surface is the key-element in splitting core and cavity. Surface modeling is the salient feature of Pro/E. Parting surface can be created easily in Pro/E, using surface modeling that's why it is effective for mold design.
• What is skeleton model and its advantages?
Modeling referenced by skeleton while assembling is known as skeleton model. Skeleton is a frame of an assembly generally made with surfaces and datum features, though they can have solid geometry also. Skeletons do not show up in the BOM and do not contribute to mass or surface properties. The number of features will be less, easy to incorporate changes and model regeneration time is less.
• What is Layout model?
A two-dimensional (2-D) conceptual sketches, called layouts , are used for beginning the design process and maintaining design intent as you develop solid models. A layout enables you to define the basic requirements and constraints of an assembly without having to deal with extensive or detailed geometry. This 2-D sketch can be created in Layout mode to document and annotate parts and assemblies in a conceptual way. For instance, a layout can be a conceptual block diagram or reference sketch for solid models, establishing parameters and relationships for their dimensions and placement to facilitate automatic assembly of the members. Layouts are not precision-scaled drawings and are not associative with actual three-dimensional (3-D) model geometry.
• What is ANSYS
ANSYS is a Finite Element Analysis, or FEA, modeling tool. It uses numerical methods techniques to solve many typical engineering problems. Some of the areas that an FEA model may apply to are solid mechanics, heat transfer, and fluid mechanics.
