How to Use a CNC Machine and Operate CNC Machine

Do you know what is CNC Machining?

In recent years, CNC machining has become an increasingly popular form of machining. The CNC router machine can provide higher work efficiency and higher resource utilization.

The CNC machining is a professional term often used in industry and manufacturing. It represents a series of engraving, cutting and other processing methods on raw materials through a computer-controlled machine (CNC router machine) to obtain some products. Now the technology is applicable to a variety of materials, such as wood, metal, plastic, glass, composite materials, etc. At the same time, it has been widely used in metal industry, furniture industry, mold making and other industries.So do you know how we should use CNC router machine.


How to use a CNC machine

First of all, you have to choose the most suitable CNC machine for you. For example, if you plan to process wood or plastic materials, please choose CNC router machine. But if you want to process hard materials such as metal, CNC mill machine is your best choice.


Learn the necessary skills

When a CNC machine performs CNC machining, there are mainly the following three steps.

First, draw the product graphics according to your needs in the CAD program, then convert the graphics into G code through the CAM program, and finally import the G code into the CNC machine for processing. Although some people like to write G code directly and import it into the machine, most of the operations are still more stable through the CAM program.



The abbreviation of CAD is the Computer-aided design software. It is generally a program used to draw 2D vector diagrams, 3D three-dimensional diagrams or solid renderings. Most of the graphics drawn by CAD programs are further processed by CAM programs, so that CNC machine can produce parts stably and efficiently.You can download CAD programs in most application stores. There are free and paid versions of CAD programs. The paid version is more powerful. I suggest you practice in the free version of the CAD program first, and then purchase the advanced paid version. Version of CAD.


Short for CAM is the Computer-aided manufacturing software. After you have finished drawing the graphics in the CAD program, import the graphics into the CAM program, and then you need to enter some important instructions here, such as cutting tools, cutting depth, and running speed. After you have entered all the information, it will automatically create a G code.

G Code

In general, small CNC machines and amateur CNC machines are controlled by an external CNC control system, which will import G code into the machine to control the operation of the machine. However, some large CNC machines and commercial CNC machines will directly transfer G code to the machine, thus bypassing the work content of CAD and CAM. Although this can simplify the process and design time, it is only suitable for some relatively simple tasks. If you want to create more detailed work, please try to use CAD software to create G code.

At present, the embedded control system of engraving machine is divided into two categories: panel system with buttons and display system with mouse and keyboard. Our industry refers to them as integrated machine and split machine system.

BuyCNC provides a variety of controllers for you to choose from, including Mach 3, NC-studio, DSP controller, Syntec controller and so on. And we will help you choose the most suitable Controller system. Next, I will introduce you to these control systems.

Carry out CNC Machining

1. Before using the CNC engraving machine, make sure that all connections between the machine tool and the computer are normal, and then turn on the power supply of the machine tool and the computer. After the system is started, enter the CNC router control system.

2. After opening the control system, select the “Back to Machine Origin” menu. The machine tool will automatically return to the machine origin and correct the system coordinate system. In some cases, such as after the last normal shutdown, restarting and continuing the last operation, the user does not need to perform a mechanical reset operation. When NCStudio system exits normally, the current coordinate information will be saved. In addition, if the user confirms that the current location is correct, this operation may not be performed.

3. Before processing, the user generally needs to load the required processing program, otherwise, some functions related to automatic processing are invalid. Select “Open (F)|Open (O)…” menu, a standard Windows file operation dialog box will pop up, from which you can select the drive, path and file name where the file to be opened is located. After clicking the “Open” button, the processing program is loaded into the system.

4. Determine the origin of the workpiece, move the X and Y directions of the stone engraving machine manually to the desired origin position on the workpiece, select the “Set current point as workpiece origin” menu, or set the coordinate value of the current position in the coordinate window Clear to zero, so that the current position is the starting point for processing when the processing program is executed.

BuyCNC has a complete pre-sales and after-sales system and professional technical engineers, as well as a variety of CNC machines. If you have any questions, you can contact us directly and we will patiently answer you.
