Fractory’s bending calculator helps you to get your sheet metal designs right from the start. For example, if you understand the writer's intent, it's much easier to make the corrections in the text. But if you're reading the essay without a clear understanding of intent, you might go back and forth with corrections before you come up with a finished copy. Managing tolerances is an essential part of a good DFM, and there should always be a justification for the numbers on the drawing.

How Spirit Aerosystems Uses aPriori to Identify Early Cost Outliers
It can be helpful to distinguish design for manufacturability from the closely related idea of a design for assembly. Manufacturability describes the degree to which a product can be effectively manufactured given its design, cost, and distribution requirements. To create a design that can be inspected using a functional gauge, you must design for Maximum Material Condition (MMC). A feature is at maximum material condition when it contains the largest amount of material allowed by its size tolerance.
Overwhelmed by the Complexity of Engineering Drawings?
DFM is applied during the design phase to ensure the product is straightforward, reducing manufacturing costs and complexity. DFM principles often emphasize standardization and modular design, which facilitate using standard components across multiple products. This approach simplifies inventory management and reduces the complexity of the supply chain. Suppliers benefit from producing standardized components, leading to cost savings through economies of scale.
aPriori Provides Actionable Insights for Better Manufacturing
Designers and manufacturers combine their unique expertise to identify solutions that reduce costs and lead times. While it might be tempting to specify tight tolerances across the board to ensure high-quality products, it can drastically increase costs. Use tolerances as loose as possible while still meeting functional requirements to facilitate more accessible, more cost-effective manufacturing. Every recommended change should undergo a cost-benefit analysis to determine its viability.

Design for manufacturing (DFM) is important because it can save manufacturing costs and complexity by a large margin while maintaining good product quality. Businesses may reduce material waste, improve production procedures, and boost overall efficiency by designing with ease of manufacture in mind. In addition to lowering costs, this strategy promotes a quicker time to market and increased industry competitiveness.
Cost reduction
How can you create a part or product that’s ready to move from prototype to production? Check out our article, which offers tips and tricks for designing with scalability in mind. Design for manufacturing (DFM) means taking a design-first approach to manufacturing.
Utilize Design Software and Simulation Tools
Specially designed AI software can enable visualization of manufacturing and assembly processes, so potential issues may be avoided. Collaboration between humans and machines makes for the highest level of insight and accuracy. The DFM process reduces costs, lowers lead times and improves the quality of custom parts. Design for Manufacturability plays a pivotal role in modern product development. By considering manufacturing processes from the outset, businesses can create products that are not only innovative but also efficient to produce. Emphasizing collaboration, simplicity, and continuous improvement, DFM sets the stage for more cost-effective, high-quality, and sustainable products.
More resources for engineers
A willingness to re-think a product from the ground-up is an essential element for generating the most impactful estimate. To generate manufacturing analyses during the design stage, your software must be extremely fast and very easy to use. With aPriori, the modeling process begins by analyzing a 3D CAD model to generate a digital twin. Rafael, an Israeli aerospace company, uses aPriori as their enterprise digital manufacturing simulation software including DFM analyses.
Identification of potential manufacturability issues should be highly graphical and pinpoint areas for improvement. For example, the system should be able to quickly identify any machining operations where the cycle time is abnormally high. While there may be a good reason for this, it may also identify a design flaw that, if corrected, could dramatically accelerate the manufacturing process and drive down cost accordingly.
Doing so will make manufacture less time-consuming, which will reduce cost and increase ease of manufacturing. The exact process of DFM will depend on what product is being designed and produced. Other basics of effective DFM include standardisation of parts to save on part cost, design simplicity, which may reduce the complication or number of parts required, and setup time reduction. By designing products with manufacturing efficiency in mind, companies can minimize complexities in assembly, reduce the need for specialized tooling, and optimize production layouts. Simplified designs lead to faster manufacturing processes, lower labor costs, and decreased waste, contributing to overall cost savings. By simplifying and optimizing the product design, DFM aims to achieve better manufacturability, leading to improved overall product performance and competitiveness in the market.
This approach often focuses on principles like minimizing the total number of parts used, ensuring that parts are easily insertable, and confining assembly requirements to simple, repetitive motions. In these cases, customers often spend valuable time and money on revisions and extensive back-and-forth communication with their manufacturing partner. Your parts may need to adhere to industry-specific, internal and/or third-party standards. If your components will be used in an environment in which food is present, for example, your product must comply with all food-safe standards and regulations. Consider all standards, and plan for testing to ensure that these standards are met, during the DFM process. In the era of heightened environmental consciousness, the integration of sustainable and eco-friendly design practices within Design for Manufacturability (DFM) has gained significant importance.
Keep in mind that DFM best practices look different at every precision machine shop. Some shops have specific machining capabilities, like Reata’s multi-tasking machine, that simplify otherwise complex manufacturing processes, giving customers more design freedom from a DFM standpoint. The synergy between Lean Manufacturing and DFM at Toyota is a testament to their commitment to holistic excellence. By eliminating waste, optimizing processes, and designing for efficient production, Toyota has set a benchmark for the industry. The combination of Lean principles and DFM ensures that Toyota's vehicles not only delight customers but also uphold the highest standards of quality and efficiency from concept to creation. Using standard parts and materials wherever possible can significantly reduce manufacturing costs.
For instance, reducing the total number of parts in the assembly and designing out fasteners will speed up the assembly process significantly and increase the overall efficiency. Another key factor to avoid problems down the line is to reduce the probability of incorrect assembly by carefully designing individual components so that they can only fit in a specific orientation (mistake-proofing). When designing a part for manufacturability, everyone who has a stake in the product should be involved. Some other departments involved with the product include Quality (inspection), Purchasing (material procurement), and even Marketing. The vendors from which you would be buying materials and components should also be consulted. Having all stake-holders involved during the design process will help potential problem areas come to light earlier in the process.
These and other features known to those familiar with materials and manufacturing processes must be followed religiously. To realize the full value of the insight provided by your DFM software, the final ingredient is a culture shift toward a cost-conscious, sustainable product engineering culture. Engineers are trained to think about functionality and reliability first, and design-stage manufacturability modeling represents an added analytical complexity.
