Figure 3 shows the maximum cutting speed for a 155mm diameter tube with 1.5mm wall thickness, at various gas pressures and laser power settings. (W 84) (1)

Gas pressure = Pressão do gás

A compact, cheap, easily robotically automated, laser Surfi-Sculpt machine, being able to operate at atmospheric pressure may have potential in a range of industry sectors. (W 76) (2)

Atmospheric pressure = Pressão atmosférica

Void formation necessarily implies a free surface, and is also strongly influenced by the hydrostatic pressure and the mechanism of cavitation. (W 133) (3)

Hydrostatic pressure = Pressão hidrostática
