| Summary: | The article discusses the issues of durability of a prefabricated cutting tool in the
process of metal cutting, as well as the risk of loss of its operability. In the course of
assessing the probability of tool failure in violation of the established wear criterion,
the results of a production experiment are used when roughing the Shaft part made
of a rod with a diameter of ø 58 mm made of HN77TYUR alloy. The processing of
the part is carried out with a prefabricated cutting tool with replaceable polyhedral
plates of round and square shape, having a special type of alloys: VK6m, VK8 and
T15K6. To evaluate the results obtained and describe their distribution, the authors
use the Shapiro–Wilk agreement criterion to check the correlation between the
initial data and the corresponding assumption of their normal distribution. Since
the obtained production test data do not obey the normal distribution law, the
nonparametric Parsen–Rosenblatt method is used for further analysis. |
