3ERP is an excellent, efficient, and economical machining parts manufacturer that offers various production services, including rapid prototyping, casting, and CND manufacturing. CNC machining is a computerized manufacturing process. This means that the method used computerized controls to work the machines. While it is currently one of the most common manufacturing processes, many people still do not know much about the process, including how it works. Therefore, this post gives you an overview of the CNC machining process.
How does the CNC machining process work?
The process features four significant phases. Below is a deeper insight into how each stage works;
Phase 1: CAD model design
The first and most critical phase is the CAD model designing process. Most manufacturing companies usually outsource this part of the process. However, a few create the CAD design in-house. Outsourcing usually works better because companies can count on high-quality designs and quick turnaround, thanks to the numerous CAD design professionals in the market. Understand that the CAD design significantly affects the result of the manufacturing process. At the same time, there are unlimited design options, the material, tooling design, machine capabilities, and the complexity of the machining parts. The CAD model design is the most challenging part of the process.
Pase 2: Converting CAD to a CNC program
Once the CAD design is ready and satisfactory, the next step is to convert it into a CNC program. The original format cannot run through a CNC program. The formatted file is then run through CAM software, where its elements are extracted. The extracted part geometry is used to generate a programming code applied in CNC machines.
It is worth mentioning that the programming language used depends on the type of CNC machine. The machines use different programming languages such as G-code and M-code. The programming language differs depending on the machining process, like milling and turning operations.
Phase 3: Machine preparation or setup
The setup process is usually done in two ways. The first is running a check on the machine’s condition. This ensures that the machine is in top-notch condition and will not break down between production. In case there are any issues within the machine, they must be fixed. The second part of the machine setup is attaching the workpiece. This is also when all the necessary tools and components are connected to the CNC machine. This phase is easy to accomplish.
Phase 4: Production
Once the three processes above are completed, the production can begin. All you have to do at this point is run the CNC program. No human input is required at this point because the process is automated. All you have to do is sit and wait for the process to complete.
Understand that all the phases of CNC manufacturing will give you deeper insight into the process. However, this is a technical manufacturing process that requires a lot of technological know-how. Therefore, it must be conducted by an experienced team. While there are different CNC processes and they do not work the same, the above steps are standard for all of them.
