Material suitability for CNC machining:

CNC machining can be used with a variety of materials, although some materials are better suited than others. Materials suitable for CNC machining include metals (such as aluminum, steel, brass, and titanium), plastics, composites, wood, and ceramics. In general, materials that are hard, tough, and durable are suitable for CNC machining. However, materials that are waxy, brittle, or fibrous may not be suitable for CNC machining. Before CNC machining is performed, the machinist should carefully review the material properties to ensure the tolerance and finish requirements are met.

Overview and working principle:

CNC milling machines are utilized for the milling process, which involves removing material from a workpiece using rotating cutting tools. The workpiece is held in place on a table, while the cutting tool is moved in various directions to remove material. This cutting operation can be performed in 3-axis, 4-axis, or 5-axis mode, depending on the machine’s specification.

Commonly used types of CNC milling machines:

1. Vertical Milling Machine: The spindle axis is perpendicular to the table, which allows for easy drilling, cutting, and shaping operations.
2. Horizontal Milling Machine: The spindle axis is parallel to the table, which enables cutting with larger surface area.
3. Bed Milling Machine: Uses a bed to support the cutting tools in the X, Y, and Z-axis.
4. Gantry Milling Machine: Has a bridge-like structure, mainly used for producing large or complex parts.

Overview and working principle:

CNC plasma cutting machines use high-velocity hot plasma to cut and shape metals. The machine moves the plasma torch in the X, Y, and Z directions, depending on the cutting requirements. The material is held in place on a table, and the plasma torch moves along the material surface, producing a high-precision cut. The plasma arc is generated by ionizing gas molecules, which is then used to melt and blow away the metal to form the desired shape.
