How CNC Milling Works?
CNC milling is a highly precise manufacturing process that removes material from a workpiece using rotating cutting tools. The process starts with a digital design, typically created in CAD software, which is then converted into a CNC program to guide the machine. The workpiece is securely fixed to the machine’s table, and the cutting tool rotates at high speeds, following the programmed path to shape the material into the desired form.
CNC milling can create intricate features such as slots, holes, and contours with high precision. Three-axis milling moves the tool along the X, Y, and Z axes, while four-axis milling introduces rotation along one axis. Five-axis milling allows rotation along two axes, enabling even more complex designs. This flexibility makes CNC milling indispensable across various industries, including aerospace, automotive, and medical device manufacturing.
