The size precision of laser cutting machine is made by cutting machine CNC machine performance, determine the overall precision of beam quality, processing phenomenon, including the static accuracy and positioning accuracy and repeat precision said change with cutting speed trajectory precision machining shape, namely dynamic accuracy.
Beam quality impact on machining precision roundness, from Yu Guangshu intensity inhomogeneity and the optical axis of the disorder.
Decided to the phenomena of the machining precision and the confusion of oxidation reaction heat abnormal combustion, thermal expansion, cut surface roughness, materials and other related properties of work piece.
In general materials in the process of laser cutting machine, the cutting speed faster, thermal deformation of the workpiece is small, through the precision of equipment debugging and necessary compensation program, beam quality and processing phenomenon affects the processing dimensional accuracy can be reduced to smaller degree, the cutting precision of the size of the workpiece depends mainly on cutting machine mechanical precision of the nc workbench and control precision.
