CAD/CAM Fundamentals: From 2D Design to CNC G-Code

Manufacturing requires precision, and modern production relies on CAD/CAM systems to achieve it. This course provides a complete, foundational understanding of the digital workflow used to turn ideas into physical parts. By the end of this course, you will understand the essential concepts of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM), enabling you to define geometry, select tooling, and generate verified G-Code programs for CNC machines. What you'll learn: * Understand the core differences between CAD and CAM software and their roles in the manufacturing pipeline. * Practice interpreting technical drawings and defining geometric constraints for 2D machining projects. * Master the fundamentals of tool selection, fixture setup, and work coordinate systems (WCS) in a CAM environment. * Apply common machining strategies to generate safe and efficient tool paths for milling and turning operations. * Learn the structure, syntax, and common commands (G and M codes) used in industry-standard G-Code programming. * Configure basic post-processors and perform essential tool path verification and simulation checks before production. The course begins by defining core terminology and establishing the digital design environment. We then move into practical CAM concepts, focusing on how tool geometry and material properties influence path generation. Finally, you will learn to inspect and understand the resulting G-Code output. This course is designed for absolute beginners interested in CNC machining, manufacturing technology, or product design. No prior experience with CAD software, CAM systems, or G-Code is required. Start your journey toward mastering the digital side of modern manufacturing.
