Özet
It was discovered that the machinability of CoCrMo material, which is extensively utilized in the health-care business as an implant material, may be improved through research. Three distinct cutting tools and three different cutting speeds were employed in the dry machining experiment, with three different feed rates being used in combination with three different cutting speeds (DCMT from two different firms and DCGT inserts). Cutting tools with a wide range of mechanical qualities based on hardness and toughness are available on the market today. Throughout machining, the output of a machine is defined as the average of surface roughness (Ra) and cutting temperature (T), which is estimated as the result of an experimental research conducted during the machining process. The signal-to- noise ratio (S / N) recorded during the testing was used to evaluate the results of the tests. When determining the effect of variables on Ra and T, it was determined that the Analysis of Variance (ANOVA) technique would be used. With a precision ratio of %61,4 in the analysis of variance, the feed rate was shown to be the most effective factor on Ra, while the cutting speed was found to be the most effective factor on cutting temperature (%63,9). The smallest Ra values were identified when machining at the fastest possible cutting speed and feed rate, whilst the smallest T values were obtained when machining at the slowest possible cutting speed and feed rate, respectively.
