This will allow conversion of the drawing into instructions to control the machine, 'G-code'. Next, this was imported into CAM software, in this case a package called CamBam.

First, a simple design was drawn up in CAD software and exported as a. Taking the above into account we can set about generating files for test cuts. From design to cutting: implementing the basics In the case of the Hypertherm Powermax45, this is 275 VDC. The arc voltage will vary accordingly, up to a maximum 'open circuit' voltage. Since the power supply provides constant current, the total energy delivered by the torch depends on the cut height, as a greater height requires a larger voltage to 'jump' the gap. Below are some figures from the Hypertherm Powermax45 system manual: Material type These vary depending on the thickness and type of material to be cut, with examples typically provided by the manufacturer.

Once the arc has pierced the sheet, it has reached full strength and can be moved across the material. This arc immediately heats the sheet metal and may take some time before it pierces all the way through the material, particularly with thicker sheet stock. If close enough to the sheet metal, the arc transfers between the torch and the sheet. Upon initial firing, a high voltage spark, along with limited DC current produces a pilot arc in the head of the torch, which then projects from the end of the torch. The cutting of metal with a plasma torch happens in several steps. With this configured and fine-tuning of the X and Y axes completed in the second post, we can now turn our attention to cutting some mild steel sheet.
