Why is modelling and simulation is carried out prior to actually machining metal?

Modeling and simulation are conducted prior to machining metal to optimize the design and manufacturing process, reducing errors and material waste. They allow engineers to visualize and analyze the behavior of the final product under various conditions, ensuring that specifications are met. Additionally, simulation helps identify potential issues, enabling adjustments before physical production, which saves time and resources. Ultimately, this approach enhances efficiency and quality in the machining process.
