Understanding of the different laser cutting machine process by comparison

Understand the process of laser cutting machine by comparison of different one, general electric machining, it good electricity corrosion or fusion effect of edm and electrochemical machining two ways, electric processing used in fine machining of hard materials, roughness of incision is good, but the cutting speed is slower than the speed of laser cutting machine some orders of magnitude.
2, complex parts section cutting under normal circumstances, the punch position cut much bigger than the mould size of workpiece, some artifacts are very complex, thus formed the trimming is many Beckham shell edge, but also the second preliminary processing and repairs. And the punch forming incision is much wider than laser cutting machine, can produce a large number of scrap iron at the same time.
3, plasma cutting, cutting speed is much faster than oxyacetylene cutting speed, but the cutting quality is poor, trimming at the top is round head shape, trimming wavy, obviously prevent the arc ultraviolet (uv) radiation. It was slightly better than that of the laser cutting machine is suitable for cutting thick steel plate and the beams of high reflectivity of aluminum alloy, etc.
