Insights on CAD/CAM, CNC Machines, and Industrial Robots

Every CNC-machined part begins its life in the digital world - as a 3D model in CAD, shaped and refined through CAM strategies. Toolpaths are simulated, feeds and speeds optimized, collisions avoided. But none of this reaches the machine directly. There’s a crucial, often overlooked step in the process: post-processing.

From virtual toolpaths to physical precision - an in-depth introductory exploration of how CAM systems translate digital models into executable CNC instructions for contemporary manufacturing environments.

Every object that surrounds you - from the chair you sit on to the car you drive or the device you’re holding - is likely the result of a digital process that began long before it ever touched the physical world. Behind these creations are three quietly powerful technologies: CAD, CAM, and CAE. Together, they form the triad that powers modern engineering and manufacturing. Yet despite their profound influence, these acronyms are often misunderstood by those outside the engineering world. What exactly do they mean? And why do they matter?
