Dimensional Characterization of Surface Contours of Cut Surfaces with Plasma Straight Metallic Materials

摘要

The purpose of this paper is to analyze the dimensional accuracy of the surfaces straight edges from cutting plasma free atmosphere or water bed. The aim was to identify any defects and if bed piss water cut in some way influence the surface quality and dimensional contours right. Mechanical thermal plasma cutting bed prevents overheating of the water has the advantage that the base material and thus the parameters related to compliance with the slag assures cut pieces at the bottom, this saves the cost of production. Mechanized plasma cutting bed heat the water does not affect the value of angle tolerance compared to cutting outdoor (angular deviation determined either for parts or cut outdoor water bed ranged between 7-9 degrees/side). The causes of and ways to reduce the deviation angle cut edge is determined by other factors such as cutting speed, distance torch-material, cutting nozzle erosion.
