CNC or Computer Numerical Control is essentially a sophisticated industrial computer with machine and internal motion control software. It has various inputs and outputs that control the cutting system, height control drive motors, and other tools that are part of the cutting system.
The CNC is given instructions by the operator of the machine along with the CAM software (computer assisted manufacturing) and converts these instructions into electrical signals that control the functioning of the cutting machine.
CNC’s in Complex Plasma Cutting Systems
The CNCs that are used in industries are very robust in design and have the ability to endure long-term usage in harsh environments. However, this robustness comes at a higher cost besides these CNCs being more complex.
CNC’s in Low-Cost Plasma Cutting Systems
Low-cost, lightweight plasma cutting tables usually use laptops or PCs as the CNC. These systems are aimed at use in environments that are relatively cleaner, temperature controlled and may not function as efficiently under harsh conditions. However, these cutting systems can handle the motion and restricted input and output requisites on many small cutting machines.
In case you are using a personal computer, then the cutting system must be fitted with the latest air plasma cutter using the blowback technology to start the plasma torch that creates lesser levels of electrical noise interference. Industrial plasma cutting systems or older air plasma cutting systems use high voltage or high frequency that can hinder the working of the delicate electronic components.
Factors to Consider When Selecting a CNC
When choosing a CNC, you must look for an interface that is easy to operate. Many low-tech machines use a keyboard and mouse for control while the hi-end machines are usually equipped with touchscreen controls. The software used by the CNC must be intuitive. It is easier to learn and operate CNC software that has been designed especially for the purpose of cutting. Escco provide easy to use 3D software compatible with all our tables.

The success of a plasma cutting machine depends a lot on the CNC. Ideally, a CNC should offer the operator a consistent and reliable performance, ease of operation, increased productivity, unified communication to tools and the system, flexible system configuration, easy and simple system diagnostics, superior control of the cutting process, precise process and motion timing, and regular software updates. Keeping these things in mind will help you to meet the ever-changing and growing requirements of the cutting industry.
