CNC Machining Fundamentals: Programming Lathes and Mills

CNC machines are the backbone of modern manufacturing, turning digital designs into precise physical parts. Understanding how these machines operate and how to program them is an essential skill for aspiring machinists, engineers, and makers. This course guides you from absolute beginner to confidently reading, writing, and editing G-code programs for both CNC lathes and milling machines. You will understand how to select the right cutting tools, calculate machining speeds and feeds, and safely plan machining operations. What you'll learn: - Understand the fundamental mechanics and coordinate systems of CNC lathes and milling machines. - Select appropriate cutting tools and determine optimal machining speeds and feeds for various metals and materials. - Read, write, and edit standard G-code and M-code programs for basic turning and milling operations. - Apply modern safety protocols and best practices for setting up and operating CNC machinery. - Learn how to identify and correct common programming errors using step-by-step code analysis. - Explore the basics of how modern CAD/CAM software interfaces with CNC control systems. You will start with the absolute basics of CNC machinery, terminology, and safety before moving on to tool selection and material properties. From there, you will progress to hands-on written exercises where you will analyze and write functional control programs. This course is designed for absolute beginners, hobbyists, and entry-level technicians with no prior programming or machining experience.
