Importance of 3D CAD Modeling in Mechanical Engineering Design

April 10, 2018

Are you finding it difficult to create accurate mechanical drawings utilizing the conventional drafting techniques? Imprecise drawings may cost you both valuable time as well as money. Most of the organizations often realize the design flaws during the manufacturing stage. This may force them to revisit the design phase again.

You can use 3D CAD modeling to eliminate such problems and reduce the design costs. It increases the overall accuracy of the design and eliminates the need for redundant designs. Here we are listing the topmost benefits of 3D CAD modeling in the mechanical engineering design for you:

  • Better design quality: 3D CAD software comes with more than 700,000 standard templates of various mechanical components. By utilizing 3D CAD modeling for designing, the mechanical designers can use existing readymade templates. This ensures the design is accurate and also helps in saving time.
  • Makes the documentation process easy: The traditional drafting methods involve documenting various aspects of mechanical components manually. The method is very tedious and requires high accuracy levels. The entire process of documenting component designs is made easy by 3D CAD modeling. It comes preloaded with different documentation options like documenting geometries and product dimensions, bill of materials, material specifications, etc.
  • Enhances the designer’s productivity: The designer can visualize the mechanical component in 3D at the initial stage with the help of 3D CAD modeling. This enables the designer to make the required changes instantly thereby increasing his productivity.
  • Automatically redraws the design: The designers find it difficult to redraw the hidden parts of the components using the traditional drawing techniques. With the 3D CAD, the lines and dashes of the hidden parts are automatically redrawn from the other mechanical parts of the design. In case, there are any design changes the 3D CAD automatically redraws the lines and eliminates any chance of error.
  • Compliant with International standards: When 3D CAD is used to design mechanical components, it ensures the designs conform to the international standards. The 3D CAD supports a range of drafting platforms like ANSI, BSI, CSN, DIN, ISO, GB and GOST drafting platforms. Compliance with the industry standards results in better outputs.
  • Cost Optimization: 3D CAD comes with numerous standard designed components that save the design engineer from the trouble to design them from the scratch. This saves the crucial time and optimizes the cost. As obtaining the licensed modeling software is often expensive, outsourcing 3D CAD modeling is preferred option to save the costs further.
  • Reduction in design time: Faster development is promoted by getting a virtual CAD model in the design phase. It helps the engineers in completing the design and getting the mechanical component into manufacturing much faster.
  • Saving data and drawings for future: The designs created on CAD can be saved for future reference with ease. Few standard components may not have to be redesigned again thus saving a lot of time for future designs creation.
  • Better visualization: The 3D CAD modeling provides best visual images of the components which have to be designed in 3D. The components can also be animated and their functionality can be observed. With the help of visual graphics, clients can understand the properties and features of the component better. This helps to demonstrate the mechanical component’s functionality to the client and making a proposal.

How Rapid prototyping helps you Design and Develop Products quickly

February 13, 2018

Product design failure in the development stage is a huge loss for the organization in terms of man-hours and the money invested in the development process. A tangible prototype of the product makes the complex product design looks simple. It helps product designer and engineers in visualizing and analyzing the actual part of the product before the development stage. This drastically reduces the chances of product failure to a great extent.

It helps you to develop every component of the complicated product in stages and compare every part of it with the prototype prepared. Any deviation from the prototype can give you a clear indication of the design failure of the part and it helps the development team to rectify the error immediately.

Why Rapid Prototyping?

  1. Clear understanding and visualization of the Design Concepts
    It acts like a POC for the client and it’s easier to understand the design rather than struggling to visualize by looking the design on the screen or paper. It helps the designer to understand the look and feel of the design rather than having a virtual design through CAD model.
  2. Quick changes or modification
    Having a visible and tangible model provides manufacturers with the better understanding of how the product may look like. It helps them analyze the actual design and suggest correction or modifications quickly which can be incorporated to make the product design perfect before advancing to the manufacturing stage.
  3. Reduction in monetary investment and time consumption for Designing
    Rapid prototyping creates a model very similar to what an actual product can look like. This eliminates a need for preparing molds and use of other software to create a model. The existing CAD software and printing equipment are sufficient to create a rapid prototype which gives you a feel of an actual model. This not only result in saving of time and cost invested in creating the actual models but also results in overall reduction of your time to market.
  4. Product Customizations
    Rapid prototyping empowers you in developing the customized products with ease. A small modification in CAD model is sufficient to create a modification in the existing design without the need for any special tool or process.
  5. Higher Accuracy level in designing
    The material used for the prototyping has similar properties of the actual product. This makes it easier to perform the physical tests and identify the flaws and errors prior to the actual manufacturing process. This helps manufacturers to avoid the risk of halting the manufacturing process at a later stage.

Reducing the Cost of On-Road and Off-Road Vehicle via Value Engineering

February 6, 2018

There is a rapid increase in competition these days and various organizations across the globe sought to create higher value in their automotive products for the customers. This growing competitiveness is leading to customers demanding high-quality products with better functionality, without an increase in price. Therefore, the OEM’s in automotive industry must include projects which are designed to lower the product cost and enhance the value to the customer.

The product’s performance and a major part of its cost are defined in the development stage. To optimize these two parameters, a correct approach of cost management in the product development process is needed.

The Costs to be Targeted for Reduction

A vehicle is composed of complex sub-systems and interfaces. If you are targeting a cost reduction in a complete automobile, it’s imperative to understand the build-up costs involved in manufacturing of the vehicle. The cost build-up in a vehicle begins right from the concepts designed for the simplest support brackets up to the last operation on the assembly line and further till the product is displayed in the showroom.

Some of the costs during this process can be controlled directly and other may require large-scale re-engineering program to keep them low. The total direct manufacturing cost of the vehicle becomes the base reduction cost because there is no engineering control over other components.

The Cost Flow Analysis

The first step in cost flow analysis is to understand how the cost flows inside the vehicle. You may need to identify and differentiate the high cost and low-cost items in a vehicle. The cost flow analysis is used to realize and shortlist areas with the low, medium and high potential of cost reduction. The analysis presents a roadmap for the rest of the cost reduction activities and we can prioritize and target strategic areas of reduction.

Approaches to Cost Reduction

The complete cost reduction approach is multifaceted and involves various variables such as form, fit, function, etc. which have to be considered and balanced. There has to be an outline to systematically evaluate the designs while ensuring a broad level perspective on all the aspects of product development. The various cost reduction approaches are listed below:

  1. Direct Material Cost Reduction: This can be achieved either by reducing the material from a design or by using an economical alternative. Before opting for material reduction it’s vital to understand the design’s function and analyze how it behaves under load conditions. Then redesign the product using less material and without causing significant change in the component’s form.
    When re-designing the existing component using alternate material changes, various aspects of initial design have to be considered. Extensive redesigning and cost reduction has to be calculated considering the changes in the downstream cost components. The change of material must save cost as well as improve the end function of the component at the same time.The third approach for direct material cost reduction is to opt for weight optimization of complex components using FEA (Finite Element Analysis) or to perform FOS (Factor of Safety) analysis on existing designs to identify the areas with more than necessary material conditions.

 

  1. Manufacturing Process Cost Reduction: In this approach manufacturability and assembly aspects of designs are involved to identify and evaluate different possibilities to manufacture the same component using alternate process which is cost-effective. This helps save cost by simplifying the overall production process while reducing the lead time. Minor re-designs can lead to better the manufacturability of various vehicle components. This process can be used to improve their end functionality as well as simplifying the overall design. The approach can be extended over to improve and simplify the overall manufacturing process.

 

  1. Parts Standard Cost Reduction: This approach brings about standardization in the designs. This means the overall modularity of the systems has to be improved and the part commonization has to be promoted as much as possible in the overall design of the vehicle. Commonization helps eliminate components which would have been fulfilling the same functionality and brings uniformity in operations while reducing the overall costs.

 

  1. Supply Chain Cost Reduction: Organizations can outsource their production plants to countries that provide large scale high volume production and cheap labor. This will reduce the landing costs of parts and the manufacturers can also reduce costs by locating the sources near markets or production facilities. The logistic network can be assessed and costs can be optimized by redesigning for improved handling and containerization.

 

  1. Cost Reduction through Design Innovation (CRDI):This approach involves redesigning that can trigger resultant engineering changes to such an extent that it becomes a new product development in itself. The investment in this process is huge and has longer ROI period. Thus, though Cost Reduction through Design Innovation is most powerful and must be used judiciously. CRDI can be realized in terms of overall system level simplification. These innovations should target towards a systematic combination of multiple functions which eliminate several others in turn and lower the overall cost.

At Technosoft, we use a combination of various approaches discussed above to carry out a systematic study and redesign of systems and components for on-road as well as off-road vehicles.
