What is a CNC plasma cutting machine?
Why CNCs are employed
Plasma cutting torches are routinely used to cut metals for a range of applications. A handheld plasma torch is a good instrument for cutting sheet metal, metal plates, straps, bolts, and pipes, among other materials, swiftly. For back-gouging weld joints or eliminating bad welds, handheld plasma torches can make an effective gouging instrument. Small forms can be cut from steel plate using a hand torch, but it is hard to achieve sufficient part precision or edge quality for most metal manufacturing. Therefore, a CNC plasma is required.

A “CNC plasma” system is a machine with a plasma torch that may be guided by a computer along a predetermined route. CNC stands for “Computer Numerical Control,” which refers to the use of a computer to control the movements of a machine based on numerical codes in a programme.
Hand Plasma vs Machine Plasma
Plasma CNC machines often use a different sort of plasma system than hand-held plasma cutting applications, one built expressly for “mechanised” cutting as opposed to hand-held plasma cutting. Mechanized plasma systems use a torch with a straight barrel that can be handled by a machine and have an interface that can be automatically controlled by the CNC. Some entry-level devices, such as the PlasmaCAM machines, may carry a torch meant for hand-held cutting. However, any equipment built for real manufacturing or fabrication will have a torch and plasma system that is automated.

The CNC may be a machine tool controller with a proprietary interface panel and a particularly built control console, such as a Fanuc, Allen-Bradley, or Siemens controller. Or it might be as simple as a Windows-based laptop running a specialised application and interacting with the machine drives over the Ethernet interface. Numerous entry-level equipment, HVAC machines, and even certain precision unitized devices are controlled by a laptop or desktop computer.
The CNC controls the motion of the torch to cut components from steel plate. A part programme, which is often only a text file containing “M-codes” and “G-codes,” specifies the part’s contours and when the torch should be turned on and off. Typically, a piece of software known as a “post-processor” generates component programmes by translating the geometry of a part from a CAD file into M-codes and G-codes that the CNC can understand.

Driving amplifiers, motors, encoders, and cables are necessary components of a CNC plasma machine’s drive system. At least two motors will be present, one for the X-axis and one for the Y-axis. Each motor is equipped with a driving amplifier, which converts a low-power signal from the CNC into a higher-powered signal to drive the motor. Each axis is equipped with a feedback system, often an encoder, that generates a digital signal showing the axis’s displacement. The position signals from the encoder are sent back to the CNC by cables.
The CNC reads the part’s programme and then sends signals to the machine’s driving system to move the torch in the prescribed direction and speed. The CNC analyses the encoder data and modifies the driving signals as necessary to maintain the torch’s travel along the specified route. All of the electronics in the CNC and drive system operate and communicate with lightning speed, often monitoring and updating position data every few milliseconds. This enables the machine motion to be sufficiently smooth and accurate to create plasma-cut components with smooth, straight, consistent edge quality and exact part dimensions.
A CNC plasma system will also include an I/O system, which is an electrical system that handles Inputs and Outputs. This is how the CNC switches on the plasma at the correct moment, for instance by activating an output that shuts a relay. The CNC utilises inputs to determine when the plasma arc has begun and is prepared to move. Those are the most essential Inputs and Outputs, although there may be many more.
Additional subsystems and features, like arc voltage height control systems, plasma bevel systems, integrated plasma control systems, etc., may be incorporated. However, the above-described fundamentals of a CNC plasma cutter will be shared by all such machines, from the simplest to the most complicated.
