CNC Milling FAQs

Tool offset refers to the adjustment made to account for the position and size of a cutting tool in CNC milling. It ensures that the machine accurately follows the programmed path by compensating for the tool’s length and diameter. This helps achieve precise and consistent part dimensions.
CNC turning involves rotating the workpiece while a stationary cutting tool shapes it — typically used for cylindrical parts. In CNC milling, the cutting tool rotates while the workpiece stays still or moves in a controlled way, making it ideal for more complex shapes and surfaces.
5-axis CNC machining refers to machines that can move a tool or part along five different axes simultaneously. This allows for more complex and precise shapes to be made in a single setup, improving accuracy and reducing production time.
While both machines are used for cutting, CNC routers are typically designed for softer materials like wood, plastic, and foam and operate at higher speeds. CNC mills are more robust, work at lower speeds, and are better suited for cutting harder materials like metals.
CNC mills can work with a wide variety of materials, including metals like aluminum, steel, titanium, and brass, as well as plastics such as ABS, nylon, PEEK, and polycarbonate. Some mills also handle composite materials and certain ceramics depending on the machine’s capability.
