Fabricating sheet metal is a comprehensive process that involves making machines, parts, and structures from different kinds of flat stock metal. In manufacturing, this process is crucial because it creates the needed components for many industries, from automotive to aerospace. Sheet metal fabrication greatly affects the efficiency, cost, and quality of the final product. And so, the employed techniques must be chosen wisely. There are many technologies used in sheet metal processing, and each has its unique advantages and is better suited to different tasks. For example, lasers are of such great precision and speed that they are usually employed to cut intricate designs. By contrast, stamping is a much cheaper way—with tools that are much less expensive to buy and operate—to create shapes in large quantities.
Computer numerically controlled punch presses use computer-controlled machines to create patterns or forms. These CNC machines selectively punch holes into the material. When deciding on what processing technology to use, a project’s resources and the capabilities of the project’s equipment must be taken into consideration. Assembly of sheet metal parts can be achieved through various methods, each of which has its own strengths and weaknesses. Welding, for instance, is a very common method that fuses parts together securely and permanently. Riveting connects metal parts together securely but is not a permanent solution. So when a project calls for punching operations to be done, it is advisable first to consider the part to be punched, then to make a decision based on both the project’s resources and its equipment capabilities.
The benefit of bolted connections in assemblies is the ability to easily disassemble them. This is really good for maintenance and works well for modular structures. But what we really need to do is think carefully about the bolted connection when we're designing the thing, to ensure that it serves the assembly of the final product well enough. There are too many instances where we don't consider the assembly during the design phase and consequently end up with parts that serve no coherent function, that don't fit together well, or that don't work at all. When we design for ease of assembly as well as for function, we get better products.
A manufacturer can focus on design for manufacturing and can enjoy several benefits—namely, lower production costs, greater efficiency, and improved product quality. To achieve this, DFM counselors work with designers as they consider working drawings and prototypes. The DFM counselor’s aim is to catch potential manufacturing problems before they happen. That's the essence of DFM. In a nutshell, DFM is an effort to smooth the way for the assembly line. In conclusion, sheet metal fabrication is a mule such process that requires natural occurrence and consideration of a number of variables. From top to bottom and side to side, a sheet metal part must demand the way of a DFM.
