Friction Is a Variable: Why Moving Mechanisms Change Over Time One of the most common simplifications in mechanical design is treating friction as a constant. During calculations and simulations, a single coefficient is often assigned to a sliding surface or bear... 2026年7月20日 Advanced Structures & Lightweighting
Designing for Maximum Material Condition: Catch Problems Before Production Does Most CAD assemblies are validated using nominal dimensions, where every feature is assumed to be exactly at its target size. While this creates a clean digital model, real manufacturing never produces... 2026年7月20日 Design for Additive Manufacturing
From Pass/Fail to Process Capability: Why Cpk Tells the Real Story Traditional pass/fail inspection answers a simple question: did this individual part meet specification? While that information is necessary, it provides little insight into whether the manufacturing ... 2026年7月20日 Repeatability and Process Control
More Fasteners Do Not Automatically Create a Stronger Assembly Adding fasteners often feels like a straightforward way to increase structural strength. If a joint appears vulnerable, the instinct may be to add another bolt, another screw, or another attachment po... 2026年7月14日 Advanced Structures & Lightweighting
Tooling for the Pivot: How Early Simulation Protects Late Material Changes Material requirements do not always remain fixed throughout product development. Thermal targets change, chemical resistance becomes more important, or testing reveals that the original material canno... 2026年7月14日 Industrial Applications & Use Cases
Tolerance Stacking: When Small Variations Become a Big Assembly Problem Tolerance stacking is one of the most underestimated risks in mechanical design. A single ±0.1 mm tolerance may appear insignificant when reviewing an individual component, but assemblies rarely depen... 2026年7月14日 Repeatability and Process Control
The First 10% of Design Locks in 70–80% of Manufacturing Cost Many organizations focus heavily on reducing manufacturing costs after production begins, but by then most opportunities have already disappeared. Industry experience consistently shows that the earli... 2026年7月7日 Design for Additive Manufacturing
Don’t Let the Toolmaker Decide Where the Flash Goes Every molded component requires a parting line, but where that line is located should always be a design decision, not a manufacturing assumption. If engineers fail to specify the desired parting line... 2026年7月7日 Design for Additive Manufacturing
The T0 Triage: Evaluating the First Shots Without Overreacting to Cosmetic Flaws The first shots from a new production tool, commonly known as T0 samples, are intended to validate the process, not to represent final production quality. Yet many projects lose valuable time because ... 2026年7月7日 Repeatability and Process Control
Myth: Simulation Is an “Extra” Cost. Fact: Simulation Is an Insurance Policy Against a $50,000 “Oops” in the Tool Shop. Engineering simulation is sometimes viewed as an optional expense that can be skipped to accelerate development or reduce upfront costs. In reality, simulation is one of the least expensive ways to pr... 2026年7月1日 Repeatability and Process Control
The Silent Killer: How a 0.5 mm Tolerance Creep in a Sub-Component Led to a 15% Field Failure Rate Most field failures are not caused by catastrophic design errors, they result from small dimensional variations that accumulate throughout an assembly. In one manufacturing program, engineers traced a... 2026年7月1日 Repeatability and Process Control
Designing in a Vacuum: Creating CAD Without Knowing the Specific Machine or Press Size the Part Will Run On A CAD model can be geometrically perfect and still be impossible, or unnecessarily expensive, to manufacture if it is designed without considering the equipment that will produce it. Every manufacturi... 2026年7月1日 Design for Additive Manufacturing
