How CNC Milling Works?

CNC milling is a highly accurate manufacturing method that shapes a workpiece by removing material with rotating cutting tools. The process starts with a digital design, usually developed in CAD software. This design is translated into a CNC program that controls the milling machine’s movements.

The workpiece is firmly clamped onto the machine’s table, and the cutting tool, spinning at high speeds on a spindle, follows the programmed path. It performs precise cuts to form the desired geometry. CNC milling is capable of producing complex features like slots, holes, and contours with exceptional precision.

Three-axis milling operates along the X, Y, and Z axes. Four-axis milling introduces rotation around one axis, while five-axis milling includes rotation around two axes, allowing for the production of more intricate and complex parts. This flexibility makes CNC milling a critical process across many industries, including aerospace, automotive, and medical technology.

Advantages

Advantages of CNC Milling

CNC milling provides a wide range of benefits for modern manufacturing:

CNC milling and CNC turning are both subtractive manufacturing techniques, but they differ in the way material is removed.

In CNC milling, the workpiece remains fixed while the cutting tool moves along multiple axes to remove material and shape the part. This method is well-suited for creating complex components with features like slots, holes, and contours.

Conversely, CNC turning involves rotating the workpiece as a stationary cutting tool removes material. This process is ideal for producing cylindrical parts such as shafts, rings, and bolts. Although milling can handle more intricate geometries, turning is generally faster and more efficient when manufacturing round components.

CNC milling and CNC routing both use computer-controlled machines to cut materials, but they are intended for different applications.

CNC milling machines are built for precision machining of metals, requiring high rigidity and the capacity to withstand substantial cutting forces. They are ideal for producing intricate, complex parts with tight tolerances.

In contrast, CNC routers are generally used for softer materials such as wood, plastics, and composites. They operate at higher speeds and are well-suited for cutting large sheets into parts where precision is less critical. CNC routers typically feature a gantry-style design, enabling efficient handling of large workpieces, whereas milling machines focus on detailed and highly accurate machining.

When a 3D model or drawing does not specify a fillet size, the standard approach is to apply fillets with a radius that strikes a balance between strength and machinability.

Typically, fillets with a radius ranging from one-third to one-fifth of the cavity depth are used. For general applications, a fillet radius of about 1 mm to 3 mm is common. This range helps minimize stress concentrations and enhances the overall durability of the part.

That said, the exact fillet size can vary depending on the material and the specific design requirements. Larger fillets are generally favored for softer materials, while smaller fillets may be chosen for harder materials to maintain structural integrity without sacrificing precision.

Vertical CNC milling machines, characterized by vertically oriented spindles, are well-suited for precision machining of smaller components, providing excellent visibility and versatility for operations such as drilling and boring. Horizontal CNC milling machines, with their horizontally oriented spindles, are better equipped to handle larger, heavier workpieces, offering greater stability and more efficient chip removal. For projects that involve extensive material removal and require high durability, horizontal milling is typically preferred. Conversely, vertical milling is ideal for detailed, intricate work. The choice between these two types depends on your specific CNC milling requirements, whether you prioritize precision or high-volume machining.

In CNC milling, tool offset refers to the adjustments made to compensate for the tool’s dimensions—specifically its length and diameter—during the machining process. These offsets ensure the cutting tool operates precisely in relation to the workpiece. By correctly setting tool offsets, the machinist establishes the accurate starting point for machining, guaranteeing that the part is produced according to exact specifications. Proper tool offset management is essential for achieving precise and consistent results in CNC milling operations.

5-axis CNC machining involves a process where a CNC milling machine can move the cutting tool along five different axes, enabling highly complex and precise machining. In this configuration, the X, Y, and Z axes represent the basic linear movements found in a 3-axis machine. Additionally, the table can rotate around the A-axis, similar to a 4-axis machine. What sets a 5-axis machine apart is its capability to pivot the table or tool head around a fifth axis, the C-axis, allowing the tool to approach the workpiece from almost any direction. This flexibility makes 5-axis CNC machines ideal for producing intricate parts with complex geometries, as they can machine multiple surfaces in a single setup.

CNC mills are capable of working with a wide variety of materials. Common metals used include aluminum, brass, and steel, each providing unique properties suited for different applications. CNC milling is also effective on various plastics such as ABS, acrylic, polycarbonate, and polypropylene, which are appreciated for their versatility and machinability. This broad material compatibility enables CNC mills to serve numerous industries, ranging from aerospace to consumer products, making them highly versatile manufacturing tools.
