The metal stamping production method has been around since the early 1900s and remains essentially unchanged to this day. For decades, the method's various operations were performed by hand until the introduction of hydraulic and mechanical presses. While the presses themselves were (and are) power sources for the metal stamping method, they were also (and are also) the bottlenecks to greater efficiency and precision. Ever since the dawn of the Industrial Age, engineering has aimed at finding ways to eliminate (or at least minimize) inefficiencies and to compensate for as many human errors as possible, both in the design and in operations. The methodology of metal stamping hasn't changed appreciably in the last hundred years, even though the tools with which one works have improved greatly.
Metal stamping processes are augmented by artificial intelligence. In this context, AI primarily means machine learning algorithms that work with enormous datasets to uncover patterns and tweak process parameters for optimal performance. In a stamping scenario, an AI system has to understand not only the material being stamped but also the way the tools used in stamping behave, and it must have a strong grasp of the various process conditions that can lead to a reduction in stamping productivity. One way it can predict when the metal stamping hardware (the stamping press itself) is going to fail is by monitoring performance metrics in real-time. The AI can get much more ambitious in its overall predictive capabilities when it combines the ability to monitor in real-time with the knowledge it has of the stamping process.
Quality control in the metal stamping industry benefits from the use of artificial intelligence (AI). Stamping outputs are examined using algorithms in image recognition and data analytics. These components of AI enable the defect detection capabilities of quality control to ramp up from the human eye to scrutiny at a much greater level; they enable the careful inspection of the finished product and the analysis of every part in a stamping die set.

When these components of AI are put to work in quality control, they allow for the fine-tooth comb inspection of every single part. And they optimize the process of conducting said inspection. AI allows the system to do what a human inspector can do but with greater ease and far better results. And in the quality control process of the metal stamping industry, results are what really counts.
Driven by artificial intelligence, simulation models and digital twins emulate the stamping process. To create these virtual twins, manufacturers must first develop a virtual prototype of the finished part. They must then use that prototype to create a simulation of the stamping operation itself. These two steps yield a digital twin of the part and its stamping operation. The simulated operation reveals how the part will behave during stamping, how the tools used in the stamping operation will move, and where any potential trouble spots lie. Once the simulation is complete, the manufacturer can study its results and make any necessary adjustments to the stamping process before actually using the tools to stamp the part. In this way, trial and error are minimized, and the process becomes much more efficient and sustainable.
AI is now driving continual innovation in the metal stamping industry. Metal stamping, as a subset of smart manufacturing, can derive enormous efficiencies from robotics-driven automation. So, too, can tooling, the essential technique in metal stamping. AI-driven optimization of processes and systems creates efficiencies, not just in individual manufacturing steps and stages but in entire workflows and value chains. Indeed, the potential for value creation at the intersection of AI and metal stamping is enormous.
