CNC (Computer Numerical Control) involves the automation of machine tools through pre-programmed sequences of commands. These commands control the movement of cutting tools, allowing users to create complex and precise parts.
CNC machines are widely used in manufacturing, prototyping, and hobbyist projects. This training program focuses on using a CNC router suitable for cutting wood, plastic, and some metals. The CNC’s versatility makes it ideal for producing parts ranging from simple engravings to complex shapes.
Key topics covered in this program include machine capabilities, material properties, tooling, CAD and CAM workflows, and safe operation practices. By the end, you will have the skills to design, program, and operate CNC machines independently for a range of projects.
The program is structured into two Parts:
First Part: An online module where you will review program materials, create a project design (CAD), and set up machining (CAM). An instructor will be available to answer questions and provide guidance. You will also prepare the material that you will be machining during this Module.
Second Part: An in-person training module, lasting 3-4 hours, which covers the safety aspects of CNC operation, machine setup for your project, operation, and basic troubleshooting and shutdown procedures.
For the training, you will need a small project as your learning object. The project should meet the following requirements:
Small Scale: The project should have a short machining time to allow the training to focus on machine setup and operation rather than extended periods of cutting.
2-3 Operations: The project should involve multiple machining steps, including machining strategies, tool changes, or repositioning of the workpiece.
Inexpensive Material: Use easy-to-machine materials like MDF or softwoods, which are affordable and easy to replace. At least one face must be flat for mounting, and ideally all sides should be flat.
