Jorge Muract and La Escuela Técnica Roberto Rocca

Computer Numerical Control (CNC) Machining is the process through which computers control machine-based processes in manufacturing. The kinds of machines controlled include lathes, mills, routers and grinders – all used for manufacturing of metal and plastic products.

In this course, you’ll learn the ins-and-outs of CNC machining; building the essential knowledge to develop and operate a project with a CNC machine.

From plan interpretation to machining and quality control, you will learn how to make the right decision in every stage of a project through videos and interactive activities.

Reviews summary

Practical beginner intro to cnc

According to learners, this course offers a solid introduction to Computer Numerical Control, particularly well-suited for beginners with little to no prior experience. Many highlight the interactive simulations as a key strength, finding them highly helpful for understanding practical concepts like G-code generation and machine operation. While providing a strong foundation in the basics, some reviews indicate the content can be too basic for those already working in the field or seeking advanced techniques, suggesting the need for supplementary learning. Despite some older mentions of technical issues or uneven pacing, recent feedback is largely positive, emphasizing the course's effectiveness as a first step into the world of CNC.
