The Ultimate Guide to CNC Control Panel
The Ultimate Guide to CNC Control Panel Machinery is the foundation of the manufacturing industry. However, how to control them? Like using the computer by keyboard, there is a panel to control the CNC machine, called a CNC control panel.
A CNC control panel is considered the brain of the CNC machine. People usually learn about the machine itself, not the panel board. However, knowing the basic knowledge of the panel board is also essential. As one of the leading CNC control panel manufacturers in Taiwan, YEU-LIAN will talk about it today.
What Does CNC Mean?
First, let us learn about the CNC before talking about its panel. CNC stands for the term ‘Computerized Numerical Control’, it is the computerized manufacturing process which the movement and velocity of the machine were programmed and coded in advance. The operator uses computer software like CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) to write program code files, these code files are about setting speed, movement, feed rate, axel/spindle speed…. etc. The operator makes the CNC machine read and follow the commands. It produces or processes the wished products in a short time with high accuracy.CNC machinery is automated machines that contain various industrial manufacturing techniques, such as milling machines. lathe, gri/znding machine, etc.
CNC machines achieve continuous manufacturing with high accuracy and high speed without human error, human fatigue and high labor costs. Complete various tasks in one procedure with high accuracy and shorter time. They are programmable and could be controlled from a far distance. In addition, editing program code is also quick and efficient.
Nowadays, they play a crucial role in the manufacturing industry.
What Is a CNC Control Panel?
After writing program codes, how do we control the machine? As we mentioned, the machine operator writes and enters the program code such as G-code and M-code via software, then they use the control panel of the machine to adjust the details. The controller and control panel are the connection between the computer and CNC machinery components to transmit the control signal into motor movement/spindle and axis speed. There are various types of them, such as point to point/matrix/scan/lock code.It is a panel that has function keys, switches, and a screen. A CNC operator should know the control panel well before using it, not only how to operate, but also the components of the control panel. We will talk about its layout and common components in the next section.
Layout of the CNC Control Panel
Control panel layout, sheet metal, and configuration vary by different types, needs, and uses. Also depends on the types of industrial CNC machine tools such as lathes, double lathes, milling machines, grinding machines, etc. Here we will talk about common buttons and internal components in most of them.Check out our ODM process of the control panel here
Panel Board Function Keys
- Power on/off key: Turn on or off the machine.
- Display screen: Shows the parameter.
- Edit: Editing the program code
- Jog keys: Move more than one axis manually.
- MDI: Manual data input. The operator can enter the code manually one by one.
- MPG: manual pulse generator
- MEM: Memory mode. Operating the machine with pre-programmed code.
- Cycle Start / Feed Hold: Restart or hold the operation
- Coolant
- Letter & number key
- Emergency stop: Stop all activities and power supply.
- Rotary Switches: Each rotary switch has a different function, such as adjusting feed rate/spindle speed/changing mode… etc.
The Internal Components
- Circuit and relay protection
- Breakout board
- IO Board: Input / Output signals between the panel and other components.
- USB to PC port: connect with the computer
- Other Connecting sockets: connecting to MPG/servo driver /encoder…. etc. Emergency stop: Stop all activities and power supply.
- PLC (Programmable Logic Controller): It is an industrial computer that sends commands to the output using programmed input signals. It provides sequence motion control for multi-axes machine tools.
- DNC (Direct Numerical Control): Allows one computer connect to multiple machines
- Power supply
Advantages Of Using Well-Designed CNC Control Panels
Now that we know the components of the control panel, you might wonder what makes one control panel considered ‘well-designed’? Aren’t they just installing many buttons and switches on the board? What are the advantages if you use a well-designed panel? Many things must be considered when designing a custom CNC control panel. Not just simply installing buttons, layout, and configuration space are critical. If it is designed according to the user’s operating habits is the best, because it is easy to use and reduce unnecessary actions.- Layout and component configuration: Easier to learn, operate, maintain, and replace. The training of a new operator will be faster, causing an increase in productivity. Consider the ergonomic design and optimize the operating experience. Like YEU-LIAN’s Crystal Acrylic Button Switch Milling and Boring Machine Operator Panel.
- Panel Space: Consider the future expansion and current need. Also need to prevent from high temperatures, components are too many and too crowded.
- Panel Size and key button material: Not too crowded or too wide. And the size of the panel should be suitable for the machine and factory environment. It is suggested to choose buttons that are resistant to vibration, shock, and mistaken touch prevention design.
- Reliability and safety: Implementation of power supply, circuit, and breakdown board requires attention, not only the safety but also have good performance.
- Wireway: The well-distributed cable not only saves energy but also prevents high temperature or electricity risk. Ensure the connection is smooth to have excellent efficiency and performance.
Conclusions
In the automation, the control panel is considered the core of the CNC machine, now we understand its basics. Being considered the brain of the CNC machine, a well-designed panel is not only user-friendly, but also increases working efficiency, reduces human error, and optimizes energy use. It needs time and cost to train operators to know control panel functions, however, the automation would increase productivity Besides, the working environment might be high or low temperature, and panel board material selection is important. And the integration of the automation system and CNC control panel is the essence of automation, it is nearly impossible to operate the machine without the control panel. Therefore, it is suggested to select the one that fits your operating habits, the machine, the end-product, and the working environment. Looking for a custom CNC control panel could be difficult; it is suggested to choose a reliable manufacturer such as YEU-LIAN for assistance. In summary, the CNC control panel plays an important role in modern manufacturing and automation control. We can benefit from a good automation system with a high-quality control panel and knowing more about it.With 30-year experience, YEU-LIAN specialize in customizing solutions for individual needs. We are customer-oriented, and certified by ISO9001, IP67, CE and RoHS. Looking for automation control solutions? Please do not hesitate to contact us.
