CONSIDERATIONS ON THE PRECISION OF NC MACHINE-TOOLS USED FOR NON-CONVENTIONAL CUTTING OPERATIONS
Cristina BIRIŞ, Melania TERA, Silvana ŞERB
Abstract: The paper analyses various non-conventional possibilities of cutting complex-shaped parts made of steel sheets in conditions of high part precision and short production time: abrasive jet cutting, laser cutting, plasma cutting. It focuses especially on the precision offered by the numerical-controlled machine-tools used for the cutting of metal sheets with the help of a laser, function of several influence factors and comparing it also with the results obtained with other cutting methods. Based on this, recommendations are made for the correct choice of the processing parameters and of the NC equipment to be employed.
Key words: machine-tools, numerical control, laser cutting, plasma cutting, precision
