In the aerospace, automotive, medical devices, and consumer electronics industries, CNC machined parts have high advantages in quality, efficiency, and cost. In this article, we will discuss what exactly CNC machined parts are, the uses of such parts, and why CNC machined parts are so important in manufacturing today.

What are CNC Machined Parts?

CNC machined parts are the parts made out of CNC machining which is an entirely automated process of using computer-operated tools to cut various materials into required shapes and sizes of the final products. These parts can be manufactured from a broad spectrum of materials such as metals, plastics, and composites that give those components application in aerospace, automotive, medical, and electronics industries. With CNC machining, it is possible to produce simple spare parts and at the same time complicated machineries for prototype as well as mass production. Hence, CNC machining is widely used where there is a need to achieve high accuracy, small or large repeatability, and fine surface finish.

 

How CNC Machining Works?

CNC machining work begins with a 3D model that is most often developed using CAD (Computer-Aided Design) tools. The aforementioned design is then translated into G-code or essentially machine-interpretable code as done by CAM (Computer-Aided Manufacturing) software The numerical control in the CNC machine interprets the G-code and lends itself to the desired position of the cutting tool or workpiece in the form of coordinates and cutting path. It also depends on the type of the CNC machine where some of the most typical operations are milling, turning, drilling, and grinding. The workpiece is clamped, and tools are used to gradually cut away material to give the machine the ability to produce fine form, surface profiles, and textures. CNC machines are highly automated, which causes a minimal chance of defects on a produced part.

● Repeatability: CNC machines are highly programmed allowing them to create similar parts with equal quality thus suitable for applications that require many similar parts and high usage. The machines are flexible enough to perform with high efficiency and have almost no variation between the parts.

● Complex Geometries: CNC machining can cut kerf patterns that are otherwise incompatible with craftsmanship by regular cutting techniques. Some examples of the specialization of the machines include – multi-axis machines, which are used in cutting planes in a way that can create complex geometries in the shaped parts.

● Material Versatility: It can machine all types of metals and even plastics, composites, ceramics, and other related materials such as aluminum, steel, and titanium. Due to this flexibility, it can be used across many industries and in many different ways.

● Reduced Lead Time and Increased Efficiency: CNC machines do not require any break and thus greatly improve the lead time. Automation of the process means that only a little human interference is required and that there is a great improvement in the speed of production to ensure that turnaround time is minimal yet the quality of work produced is not compromised.

● Customization: CNC machining enables the manufacturing of very complex or one-off parts to meet certain customer requirements or certain products. Wherever a unique piece or a few production pieces are required, CNC machines are useful in their flexibility to manufacture.

Common Types of CNC Machined Parts and Their Manufacturing Processes

Milling Parts

CNC milling is a process of using cutter tools to cut away a material to form flat t surfaces, grooves, holes, and different shapes on a workpiece. Milling parts can be cut without much distortion on 3, 4, or 5-axis CNC milling machines. It is especially applicable for manufacturing parts with high geometric density, under or oversize, and variant shapes.

Examples of Milling Parts:

● Brackets and Mounts: Foundries used in automotive, aerospace, and industrial applications for tying or supporting other parts.
