It is a typical and common machining process. It utilizes computerized controls to manufacture custom-designer machining parts, By optimizing the movement and operation of rotary cutting tools, the CNC machine will remove the excess material of the workpiece to achieve the required shape and dimensions. These milling parts have a good quality and precision surface finish. The milling process is welcomed in many industries because of its accuracy, consistency, and ability for mass production and stability. The serving industries include aerospace, shipping, automobiles, oil drilling, pump, electronics manufacturing, and precision engineering sectors. A CAD drawing is the beginning of the milling process, the drawing is used to control the output of the CNC machining process.
