Laser Cutting Speeds. Cutting acrylic is usually best achieved with relatively slow speed and high power. This cutting process allows the laser beam to melt the edges of the acrylic and essentially produce a flame-polished edge.. Today, there are a several acrylic manufacturers who produce a variety of both cast and extruded acrylics that feature different colors, textures, and patterns. Automated cutting HyperthermAutomated cuttingwhether plasma, laser, waterjet, punch, or something else - encompasses many different cutting processes in which the cutting tool is moved using mechanical means. This can include cutting on a XY table, or the use of other mechanical means such as pipe cutters or robots.

Contactless, laser technology overcomes the hardness of the parts and allows a very fine mark at high speed. The work is clean and indelible. The work is clean and indelible. Flexible , it is suitable for all needs and types of production, from aesthetic engraving to engraving at the highest industrial rate. Experimental Study on Fatigue Behaviour of Shot-Peened The laser cutting process is started by completely penetrating the metal workpiece, and then the laser beam moves around, melting the materials as it passes. Meanwhile, a stream of gas blows the melted materials downwards out of cut to form a hole.
