Once the procedure of 2D/3D drawings is finished, we would calculate the toolpath and simulation. In this age of information, there are many CAM software to assist this procedure. By taking into full consideration of tool shape, size, movement, and location, personnel can have a concrete understanding of material removal. Then the CAM software can simulate the movement to verify the tool path and convert it to the CNC language.
The next procedure is communication to the CNC machine. Personnel will adjust kinds of settings and input the G-code(generate by CAM) on the CNC machine to guide the movement of tooling and axis are in the correct direction.
Depending on the customers’ request, the finished part may have other finishing like polishing, plating, painting, etc. On the base of it, CNC manufacturing is like small digital manufacturing.

What is digital manufacturing?
Digital manufacturing uses a computer system to exchange information in the process from design to production. It can lower the cost of trial and error.In digital manufacturing, each procedure can receive the correct data faster from the last one. As the market and customer demand are always changing and be flexible, digital manufacturing even can make the simulation demonstration to change product fast, which can improve the production efficiency, product quality, and shorten the time to market.

Digital manufacturing contains data transmission carrier, operating and analytic personnel, and continuous operating production.
Data transmission carrier
In the process of part design, the data carrier can simulate the test of part feasibility and use sense. For expensive and crucial parts, the simulating test can eliminate poor design and absorb more ideas. The personnel can respond quickly if the part function is limited. Even the design procedure can transmit more useful data to the next procedure of prototyping.There is a concept named IIOT (Industrial internet of things). The IIOT machine sensors can have a remote control, monitoring, and analysis while producing. The sensor can help optimize the equipment, cutting direction, and maintenance.

Operating and analytic personnel
Superior and detailed data need both digital technology and personnel. Personnel’s expertise and tacit understanding of the digital system influence the whole digital system. Practical manufacturing request personnel that have an overall understanding of the analytical software and interface. Only then can the procedure processed quickly. However, the speed of technology iteration needs the personnel to follow up closely. Regular training and examination are the two factors to ensure digital manufacturing.Continuous operating production
A complete product line from design to production is the key to the digital system. This line can be different supplying chains or various departments inside a company. Commonly, internal communication will be viewed as more smoothly. Now external communication becomes the same during the introduction of digital manufacturing. The whole supplying chain is able to monitoring, analysis, and transmit the data.Why is CNC machining digital manufacturing?
The full name of CNC, computer numerical control, is essentially technological manufacturing. A complete CNC workflow contains different procedures.Once the procedure of 2D/3D drawings is finished, we would calculate the toolpath and simulation. In this age of information, there are many CAM software to assist this procedure. By taking into full consideration of tool shape, size, movement, and location, personnel can have a concrete understanding of material removal. Then the CAM software can simulate the movement to verify the tool path and convert it to the CNC language.
The next procedure is communication to the CNC machine. Personnel will adjust kinds of settings and input the G-code(generate by CAM) on the CNC machine to guide the movement of tooling and axis are in the correct direction.
Depending on the customers’ request, the finished part may have other finishing like polishing, plating, painting, etc. On the base of it, CNC manufacturing is like small digital manufacturing.

Operating software/language
CAM(Computer Aided Manufacturing) is able to generate a language(G-code) that drives the CNC machining in the right path. If G-code is a wonderful language that can be recognized by CNC, then CAM is a translator that can convert human understanding to machine understanding. After the calculation of tool path, CAM can simulate the path of cutting, drilling, milling for verification. This procedure simplifies the personnel’s work and improves working efficiency.Photo Credit：Pixabay
Operating/analytic personnel
It is not an easy job to talk with an icy machine. Before the CAM, the machinist needs extensive training, practice to operate the CNC expertly. However, it is restrictive when it comes to complicated parts. Thanks to the introduction of CAM, the machinists can produce more detailed and complex parts. They are still irreplaceable and a crucial role to the perfect part. As the communicator, the personnel uses their experiences and knowledge to be the CNC machine’s partner. The communication lowers the failure and supports the manufacturing strongly.CNC operating system
Every procedure relies on the data and feedback from the following. The data from calculation and simulation can shows specifically whether the cutting path is optimized. The CNC machine will start working automatically after settings. The working situation can be viewed as a verification for the G-code and settings. All the movements will be incorrect when wrong settings. The operating system is continuous feedback. Only the constant operating can the part be completed perfectly.Photo Credit：2fprototypes CNC Workshop
