Design and Programming- A computer-aided design (CAD) software is used to create the design for the desired cut. The design is then converted into a digital file format (usually DXF or similar) that the CNC plasma cutting machine can read.Loading the Design- The digital design file is loaded into the CNC control software of the plasma cutting machine.Material Preparation- The metal sheet or plate to be cut is prepared and placed on the cutting table. The table may include features like suction systems to hold the material in place during cutting.Setting Parameters- The operator sets various cutting parameters such as cutting speed, gas flow rates, and torch height based on the type of metal and thickness being cut.Start and Control- Once the machine is ready, the operator initiates the cutting process through the CNC control software. The software sends commands to the machine’s motors and torch control to follow the path defined in the digital design file.Plasma Torch Ignition- The plasma torch is ignited and generates an electric arc between the electrode and the nozzle. This arc ionizes the gas (often a combination of compressed air and inert gases) passing through the nozzle, creating a plasma jet.Material Cutting- The high-energy plasma jet heats and melts the metal at the cutting point, while a high-velocity gas blows away the molten metal, creating a precise and clean cut.CNC Control- The CNC control software continuously adjusts the torch height and speed based on the design, ensuring consistent and accurate cutting even on irregular surfaces.Completion and Unloading- Once the cutting is complete, the torch is turned off, and the machine completes the programmed path. The cut part remains on the table for unloading.
