an investigation of Cutting Forces and surface damage in high speed turning of inconel 718
Journal of Materials Processing Technology, 2007Co-Authors: Raju Pawade, Suhas S Joshi, P K Brahmankar, M RahmanAbstract:Abstract Knowing the stringent operating conditions to which superalloys are subjected to in automobile, aerospace and gas turbine industries, their efficient machining and generation of machined surfaces with high integrity assumes a lot of importance. Therefore, this paper presents an experimental investigation into the effect of various process and tool-dependent parameters on Cutting Forces, an indirect measure of machined surface integrity besides a detailed microstructural analysis of the machined surface damage, in high-speed machining of superalloy Inconel 718. Accordingly, the effect of Cutting speed, feed rate, depth of cut and tool Cutting edge geometry on Cutting Forces, surface roughness and surface damage in high-speed turning of Inconel 718 using PCBN tools has been discussed. The input parameters were varied as: V = 125–475 m min−1, f = 0.05–0.15 mm rev−1, d = 0.50–1.0 mm and edge geometry as: 30° chamfer, 20° chamfer and 30° chamfer plus honed. The results show that the radial and feed Force Components are almost equal and the main Cutting Force Component is two to three times that of feed and radial Force Components. The honed plus chamfered Cutting edge was influential in reducing Cutting Forces significantly. It was noted that specimens showing larger Cutting Forces generated poor surface finish as well as extensive surface damage.

in process monitoring and detection of chip formation and chatter for cnc turning
Journal of Materials Processing Technology, 2009Co-Authors: Somkiat TangjitsitcharoenAbstract:Abstract In order to realize the intelligent machine tool, an in-process monitoring and detection of Cutting states is developed for CNC turning machine to check and improve the stability of the processes. The method developed utilizes the power spectrum density, or PSD of dynamic Cutting Force measured during Cutting. Experimental results suggested that there are basically three types of patterns of PSD when the Cutting states are the continuous chip formation, the broken chip formation, and the chatter. The broken chip formation is desired to realize safe and reliable machining. The proposed method introduces three ratios, which are calculated from three dynamic Cutting Force Components and obtained by taking the ratio of cumulative power spectrum density for a certain frequency range corresponding to the states of Cutting to that of the whole frequency range of each dynamic Cutting Force Component, to classify the Cutting states of continuous chip formation, broken chip formation, and chatter. The algorithm was developed to calculate the values of three ratios during the process in order to obtain the proper threshold values for classification of the Cutting states. The method developed has been proved by series of Cutting tests that the states of Cutting are well identified regardless of the Cutting conditions. The broken chips are easily obtained by changing the Cutting conditions during the processes referring to the algorithm developed.
