PATTERNS OF CHANGES IN TECHNOLOGICAL ACCURACY OF PLANO-MILLING MACHINES DURING THE PERIOD OF THE CUTTING TOOL WEAR RESISTANCE
Keywords:
regression model, accuracy, machining, machine tool, partAbstract
Polynomial patterns of changes in the technological accuracy of the machine tool over the period of the cutting tool wear resistance were established. The software, which makes it possible to show regression models of the average value and the scattering field of the size of the manufactured parts depending on the degree of the tool wear, was developed. Based on the results of experimental studies of changes in the machining accuracy on six plano-milling machines during the wear resistance period of the cutting tool (ρ = 5 − 50 μm), regression models in the form of third-order polynomials were obtained. It was found that to ensure the machining accuracy within the tolerance (± 0.1 mm), the wear resistance period of the cutting tool should not exceed ρ = 30 μm, and the technical specification of the machine should correspond to an exceptionally high accuracy class.
