METHOD AND MODEL INVESTIGATING RELATIVE DEVIATION FROM ACCURACY IN LASER CUTTING OF C235

Nikolay Tontchev, Viktor Georgiev, Emil Yankov

This paper presents an analysis using the design methodology based on the response of investigated quantities in the optimization of laser cutting parameters in terms of dimensional accuracy for C235 products The input factors, such as cutting speed, power and carbon dioxide pressure, on the quality cut, expressed by the relative deviation from accuracy, are examined. The paper proposes an algorithm and a regression model to optimize the deviation from the dimensions between a model and a cut contour, by minimizing the error of this deviation. Based on the conducted experiment and research results, a generalized methodology was created. It can be used after a planned experiment to determine the accuracy of any contours of a test material of a specific thickness.
