In our industry, CAD software is notably used to create precise drawings and models of objects and structures. CAD was developed as a more accurate, affordable way for designers, engineers, and manufacturers to design, visualize, and test models while minimizing the chance of mistakes. As CAD allows for easy modification, documentation,...

Graphite Dust: How We Deal With the Dust Hazard

Dust: a finely powdered substance of various matters, often suspended in the air. When that suspended matter is floating around someone machining graphite electrodes, it’s graphite dust. Anyone that has machined graphite knows that the particles generated from the machining process are very fine and have a tendency to remain airborne, even when a dust collector is in use. Unlike common household dust, graphite dust has characteristics that must be taken into consideration. Dust Hazard? Dealing with graphite dust naturally brings up the question, is this stuff considered a hazard to the human body? Before answering this, we should clarify...
