Dispatch of net of machine tool of Chinese numerical control: In Laser Cutting process, generation focus and be machined the element that changes relative to positional happening between object surface is very much, by treatment workpiece surface the geometrical error of means of clip of outfit of scraggly, workpiece, machine tool and machine tool are in what laden force falls to be out of shape, workpiece is machining the heat in the process to be out of shape etc metropolis cause laser focus position and ideal to give the seat (process designing position) produce deviation. Some errors (the geometrical error that is like a machine tool) have regularity, can undertake compensating through mensurable compensation method, but some errors are random error, can pass only online detect and control will eliminate, these errors are: 1.

The object of Laser Cutting of 　 of 　 of 　 of workpiece geometry error is plank or enclothe model spare parts, as a result of the influence of all sorts of reasons, treatment object surface is had rise and fall rough, and the appearance that also can produce laminose part in the influence of the fuel factor in cut process is out of shape, to 1 dimension laser beam machining, enclothe shape in suppress what the appearance also can produce in the process is rough, all these, focus of metropolis generation laser and be happened to change randomly by the position of treatment object surface and good place. 　 of Laser Cutting 　 2.

The work that the Laser Cutting of 　 of error 　 　 that unit of workpiece outfit clip emerges processes is to be put in acicular on workbench, as a result of machining error, long with workpiece between wear away and the burn of laser, needle bed can appear scraggly, this kind rough the random error that also can produce the position between thin stencil steel and laser focus. 3.

The error 　 　 that process designing produces is in process of treatment of 1 dimension Laser Cutting, the treatment contrail on complex curved surface is to pass linear, circular arc to wait for those who plan to close, these drafting that add up to curve and real curve to be put in certain error, these errors make actual focus and the relative position that machine object surface and position of ideal process designing produce certain error. And system of some teach programming also can introduce a few deviation. (original title: The generation way of position error of focus of shallow analyse Laser Cutting) CNC Milling
