This is important because, when machines have not been correctly maintained, the safety of the operators is put at risk.

• Work Area: The work area is the part of the machine where an operator can carry out a task. The work area size will vary depending on the machine. A 3D printer, for example, will have a much smaller work area when compared to a plasma cutting CNC educational machine. The work area needs to be clean from dust and any obstructions that may have been left after a previous use. Wipe down the work area after every use and make sure that all parts are working and not loose or damaged. Lubricate the guides and rails.
• Bed Type: The bed is usually made of cast iron or aluminum and will be a flat, even surface. It can be textured and needs to be repaired and leveled as soon as any significant wear and tear is noticed. Before doing any repairs, ensure that the machine has not been moved from its usual position and measure it first. When storing, make sure it is covered with material that will hinder any foreign material from getting onto the bed.
• Control Methods: Educational CNC machines have advanced digital technology. The instructions and blueprint for the project are usually uploaded digitally. These machines now also have a touchscreen where solutions can be easily uploaded. It is important to ensure that the screen and parts are not damaged by water and wipe it down with a soft, moist cloth. Cover the machine before any storms or high-risk events occur that could damage the electronic parts.
• Tool Holders and Tool Changer: These parts of the machine are responsible for holding the tools in place. They must be cleaned after every use, and all air lines and tool holders need to be dried. If tool holders are removable, they should be removed and thoroughly cleaned. Ensure that no foreign parts or tools are left lying around once tool holders have been replaced.
• Drive System: The parts that move the tool holder are known as the drive system. Belts and leads, along with the guides, need to be cleaned and lubricated with the recommended lubricant. Ensure that all friction parts are removed and any cables are securely fastened. The drive system will differ depending on the model, so it is always best to refer to the manufacturer's instructions.
