How do you use engineering software to improve mechanical product safety?

CAD Software is the foundation of modern engineering design with the application of theories and principles that guide the final product. CAD Software is the platform where objectives and criteria of product are synthesed, validated and optimised through the modification of features and contours. This modification facilitate the simplicity of the assembly of multiple components to bring product to it intended function. Further analysis can then be used to visualise real-time situations. While collecting vital data and information that ensures the product is suitable for use at the same time meeting regulatory standards for product design and the environment.

CAD software revolutionises mechanical product safety by offering a precise and detailed platform for designing complex components and systems. It enables engineers to visualise products in 3D before construction, identifying potential design flaws or safety concerns early in the development process. With CAD, engineers can test different materials and shapes, optimising designs for strength and durability while adhering to safety standards. Advanced CAD tools also provide simulation capabilities, allowing for stress and strain analysis under various conditions, thus ensuring that products are robust and reliable under real-world usage scenarios.

CAD Software is most important for any engineering becuase without software we can not analysis the product its give measurable effeciency and accuracy and save your time, most important thing its can be change and modify, after made it can not be change. You can take approval from your senior via presentation before make product, means save time

Using engineering software to improve product safety 1. Identify Safety Requirements: Begin by defining the safety requirements and standards applicable to your product. 2. Risk Assessment: Use engineering software for risk assessment. Tools like FMEA (Failure Modes and Effects Analysis) and HAZOP (Hazard and Operability Study) can help identify potential risks and their impacts. 3. Prototyping and Testing: Combine virtual simulations with physical testing. Create prototypes and conduct tests to validate the safety of your product. 4. Compliance Verification: Use software to check if your product meets safety standards and regulations. ISO 9001, ISO 13485 (for medical devices), or industry-specific safety standards.

Using Finite Element Analysis (FEA) involves several steps: 1. **Define Your Problem**: 2. **Geometry and Meshing**: Create a 3D or 2D model of your system using specialized software. This involves defining the geometry of the components and dividing them into smaller elements (meshing). The accuracy of your mesh impacts the FEA results, so it's crucial to choose an appropriate mesh density. 3. **Material Properties** 4. **Load & Boundary Conditions** 5. **Mesh Analysis** 6. **Solve the Equations** 7. **Post-Processing** 8. **Iterate and Optimize** 9. **Validation** 10. **Documentation and Reporting**

API 579 is a widely recognized standard for FFS assessment of pressure equipment and piping systems. It provides guidelines for assessing the structural integrity of components in various service conditions, including those with flaws or damage. When it comes to performing FFS assessment using FEA for example Abaqus, the API 579 standard can be implemented through custom scripts and user-defined subroutines by Abaqus. This typically involves creating custom procedures and algorithms to implement the assessment criteria outlined in API 579 within the Abaqus environment.

Understanding flow characteristics and features in the region of interest is necessary to better design a system. This may require optical access or very highly sensitive and miniature probes. There are times where the space is not visually accessible or at conditions of high pressure and temperature making it difficult to probe. Computational Fluid Flow analysis is one way to determine the flow characteristics by numerical model modelling and analysis. The software can be so written to modify the Governing Equations to capture the physics. Once stabilised multiple parameters can be analysed to check the sensitivity and finalise the design for desired effect.

A better and deeper understanding on fluid flow or heat transfer can lead to the timely elimination of critical risks, but fluid dynamics and heat flow are well known as a parts of engineering science hard to be applied. CFD serves mainly for complex and peculiar situations when simple engineering algorithms do not work and when it is strictly required to be fully aware what is exactly the math and physics behind hypothesis and results, similar with other difficult analysis as the dynamic deformation and failure. So, software helps, but when precise results are required, expected to contribute significantly to the product safety, personnel with a high level of scientific knowledge on the respective phenomenon is preferably to be involved.

The Best part of CAM over conventional machining 1. One can virtual run the programed machining on 3D and accurately estimate time required in machine. 2. It avoids all confusion on machine Setup & Tools required for given job if virtual run is done before actual machining , hence assist in better PPC 3. Precision & Quality is better since machine takes care of operator's machining skill 4. Programmed file can be sent any where in the world and one can control on sequence of operation. Machine process can't be alterated. Hence better process control. 5. Piece to piece varrion is negligible. DFSS can be implemented easily for CAM process.

CAM software is used to generate toolpaths and control machining operations for producing physical prototypes or production parts from CAD models. By simulating machining processes within CAM software, engineers can identify potential issues such as tool collisions, excessive tool deflection, or material deformation that could compromise part quality or safety. CAM software optimizes manufacturing processes to ensure accurate and repeatable production of mechanical components, reducing the risk of defects or dimensional inaccuracies that could impact product safety.

Many startups fail to incorporate a solid PLM strategy early on. What they figure out later is they are not up to date with product features and reviews. It's already too late at that stage. They will typically then assign the too-much-needed resources to the heavy lifting of cleaning up that system. That's why it is critical to start with a solid design review and release plan.

Don't forget the importance of experimental tests alongside each simulation. According to the #MIT SMART Manufacturing webinar, simulation is merely about generating more data from a validated simulation based on appropriate experimental results.

One thing to remember is that computer aided design and FEA are powerful tools in our engineering tool box, however, they are somewhat limited. I have also found that input accuracy is important, and just because a model might "converge" in the virtual space, it does not mean that is the "right" answer. Also the ability to use the software does not always equate to good engineering design. Don't get me wrong, there is nothing wrong with both understanding and using the above software, but accurately knowing how it fits in with good product development and engineering is vital to good overall product design and safety.
