CNC or computer numerical control is a widely employed manufacturing technique that is used for various industrial applications. CNC is an advanced subtractive process in which a computer program controls the machine tools to produce a custom design. In CNC manufacturing, a piece of material known as the workpiece is used and the machine removes the layers of the workpiece to produce the final product.
This CNC cutting process is suitable for various materials, including metal, composites, glass, plastics, and more. With its fast and accurate job, this manufacturing technique is used in multiple industries, including automotive, construction, aerospace, and more. The CNC process incorporates various machining processes which include chemical, electrical, and thermal processes.
How CNC works?
The modern CNC machining setups are automated, and they operate with digital files and instructions for cutting, tooling, and other operations. Engineers can produce digital tool libraries for design or machining processes. These digital libraries will interface with the physical machines and the machines can switch the tooling automatically based on the designs.
The physical machining process first begins with designing the items using CAD software. The final 3d model defines the dimensions and other properties of the physical parts. Many programs come with an advanced CAD-CAM package, making the process seamless as no file translation occurs. On the other hand, if there is only a CAD file, the engineer must first translate it.
The software then makes the model for completing the fabrication process— after checking for errors in the model; it creates a CNC program for fabrication. In simple terms, the program is a set of coordinates that instructs the machine head during the manufacturing. Many companies accept online CNC orders where you need to provide them with the CAD file, and they will produce the design.
Types of CNC operations
CNC machining services cover multiple industrial jobs that bring more accuracy and complete the work with a faster turnaround. Following are the CNC operations:
In the drilling process, it utilizes a multiple-point setup to draft cylindrical holes in the workpiece. The machine produces the drill on the workpiece’s surface perpendicularly. The engineer can draft vertical holes with a customizable diameter depending on the job.
The CNC machine is also capable of drilling angular holes, and it requires a specialized bespoke setup before producing the holes. Some of the popular CNC drilling operations are reaming, counterboring, countersinking, and more. As compared to the traditional processes, CNC drilling is more accurate and offers a faster turnaround. You can also quickly get started with this process by searching for CNC machining in Sydney, or another city where you live on your smartphone.
In the milling machining process, the machine uses multi-point rotating cutting tools, and the setup is used to remove materials from the piece of metal or other material. In milling, the device inserts the blank piece into the cutting tool in the same direction as the tool’s rotation. It is different from the manual process where the machine inserts the material block in the opposite rotation direction.
Some of CNC milling’s general operations are cutting shallow, creating flat cavities, peripheral millings, producing deep pits, and more. The CNC milling process is also capable of producing threads and slots. Several companies offer professional CNC machining in Melbourne, Sydney, and other places to improve job’s accuracy, and quality.
In CNC turning, the machine uses a single-point operational tool to remove the material by cutting it. In this process, the engineer uses a turning machine or a lathe. The CNC machine feeds the cutting tool into the workpiece in a linear motion, removing the material from the external boundary. This process continues until the required diameter. This process is used to produce cylindrical parts, and it can make both external and internal features.
Some of the most common CNC applications are grooving, thread cutting, boring, facing, and more. As compared to the traditional process, CNC turning can perform the job at a higher frequency, saving time and operational cost.
CNC can help you scale your business process in a hassle-free & cost-effective manner. Regardless of industries, the trend of CNC machines in Australia and other countries is surging. With the advancement of Industry 4.0, companies need more advanced operations to meet customers’ demands.
