EFFECTS OF CUTTING SPEED IN FORCES, SURFACE TOPOGRAPHY AND RESIDUAL STRESSES IN MILLING OF INCONEL 718

Résumé

The heat generated in the cutting zones during milling plays an essential role in the final workpiece quality and power consumption. Surface integrity in the milling process can be influenced by tool geometries and cutting conditions, depending on the field temperature and cutting forces which the workpiece is submitted. Although, these effects in machining of Inconel are crucial as the tool life can be reduced to some seconds and more experimental studies need to be done in milling of Inconel to understand and optimize the machining process. This paper presents an experimental analysis of milling INCONEL 718 using two different cutting conditions, recommended by the tool manufacturer. Machining forces are measured during the cutting process and roughness, burr height and residual stresses are taken in the identified channels. Analysis of variance is used to compare the experimental results and calculate the effects of the factors. The results show that the lenght of cutting is the main factor that influence all the results. The two cutting speeds used (30 and 40 m/min) present no influence, compared to the lenght of cutting effect and the variance of data.
