Design Principles

"Utilize computational modelling to predict and optimize complex physical processes in design, reducing the need for extensive physical prototyping and enabling data-driven decision-making."

Understanding the complex physics of chip formation and heat generation is crucial for designing efficient and precise machining processes. FEM simulations offer a powerful, non-destructive way to explore these phenomena, enabling designers and engineers to anticipate potential issues and refine their approaches before physical prototyping.

What This Means for Your Design

Computer simulations using a method called FEM can show exactly what happens when a tool cuts metal, including how hot it gets and how the metal breaks off. This helps designers make better tools and processes.
