Abstract
This study aims to find alternatives to increase the performance of saws used in cutting materials with high chromium content, so this income is close to the performance found in cutting carbon steel, permitting then cut into pipe line currently production. At first will be analyzed the influence of parameters cutting speed and feed per tooth evaluating the number of cuts made with each saw. Then be made to optimize the cutting parameters, so as to obtain a better surface finish, operating time and the number of cuts reached. Finally, a new test will be performed with PVD coated saw (Physical Vapour Deposition). In general, it was observed that by increasing the cutting speed and feed, a better surface finish was optimized cutting process due to a shorter cutting saw and achieved a higher number of cuts. Finally, with the use of coated saw, beyond getting a better surface finish, the numbers of cuts made by the saw was about 330% greater than in the previous step.
