![]() Far more accurate than a ruler, calipers provide all the dimensions for a part or product so that it can be recreated with precision. Similar to a drafting compass, it is used to measure a product’s dimensions, including internal parts and components, with a high degree of accuracy. CalipersĪ caliper is a common but highly valuable tool. More for You: 6 High-Value Minor Degrees for Mechanical Engineers 7. These gauges are available in digital, analog, and mechanical styles. Engineers use these gauges when building and testing equipment, including critical components such as wiring, to be sure all parts have the proper tension. Top software programs for 3D printers include Fusion 360, Solid Edge, Tinkercad, and OnShape.Īlso called a push-pull force gauge, a digital force gauge has a load cell inside that measures the amount of tension or pressure for a part or component in a machine. 3D printing enhances prototype development by saving time, improving design, reducing iterations, and optimizing inventory. ![]() Mechanical engineers use 3D printers to make solid, plastic or metal parts for their designs that are tested as prototypes (function, strength, material properties) or fabricate replacement parts for equipment or jigs and part-holders. Cold forming can process metal, plastic, and other materials new machines on the market are equipped with more digital features. The metal is forced beyond its yield (elastic) limit but not beyond its tensile strength, which would result in fracture. ![]() This equipment can be inline or offline and can measure features as small as one micron in diameter.Ĭold forming is a high-speed, room-temperature forging process that cuts wire and pushes it through a succession of tool and die cavities to turn it into the required shape for the product being made. CMMs are ideal for parts and components that require extreme dimensional control and automatically measure parts to ensure they are within tolerance. Coordinate measuring machines Coordinate measuring machines (CMM) are computerized measuring devices that take extremely precise measurements. Mechanical engineers can then quickly isolate the cause of the vibration and fix it to restore smooth operation.īecome a Member: How to Join ASME 3. Springs are typically used as the isolators to minimize force and may include fluid damping, steel coil, pneumatic, and rubber components. Engineers rely on vibration isolators to detect and measure vibrations in machinery. Vibration is often a problem with equipment because it can damage components and impair performance. Depending on production needs, models range from manually loaded machines to fully-automated systems that use robotic arms for loading and holding parts. Markings range from engraving serial numbers on parts to logos, QR codes, and barcodes. Here are 10 essential tools that most mechanical engineers cannot do without.Ī fiber laser machine is essentially an engraver that uses a laser to mark metal surfaces such as anodized aluminum, zinc, and steel. As manufacturing technologies advance, especially with the challenges of smaller parts and tighter tolerances, it is more important than ever to have handheld and digital tools that provide the speed and high precision that mechanical engineers require. Engineers use a variety of tools that make their jobs easier and more efficient, resulting in higher-quality products and faster production. Mechanical engineers draw upon a wide range of disciplines for their projects, including mathematics, engineering, physics, materials science, and chemistry.
