An experimental study has been performed to assess the feasibility of using a hybrid machining system to improve the machinability of Inconel 718. An assembled plasma enhanced machining (PEM) system is described, and experimental results obtained from both conventional and plasma enhanced machining of Inconel 718 are compared. Several advantages of PEM over conventional machining are demonstrated, including improvement of surface roughness, lower cutting forces and extended tool life.

High Pressure Coolant

The automotive, aerospace and energy industries have lately increased their search for materials which must have high mechanical resistance/weight ratio and capability to maintain the mechanical properties in high temperatures and at corrosive environments in order to produce critical parts of their equipment. The nickel-based alloys are one type of materials which have been a good answer for this search. On the other hand, the very good mechanical properties of these alloys make their manufacturing very difficult, especially when machining processes are used. Among other problems in the machining of these alloys, due to the high mechanical resistance in high temperature, tool lives used to be much shorter than when steel alloys are machined, forcing cutting speeds to be much lower and, consequently, to have less productive processes. The main goal of this work was to test an alternative to increase tool life in the turning of Inconel 625 nickel-based alloy by the use of high-pressure coolant. This system was tested using different directions of the fluid flow (toward the rake face, toward the flank face and directing the fluid simultaneously toward these two tool faces) compared to the conventional way of applying fluid. The results show that the use of high-pressure coolant harms the notch wear development and, consequently, increases tool life with simultaneous improvement of workpiece surface roughness in some cases. However, the application of high-pressure coolant over both flank and rake faces at the same time did not provide any improvement.

Titanium Alloy Ti6al4v

Milling tests were undertaken to analyze and compare the machinability of hydrogenated titanium alloy Ti6Al4V. Uncoated WC-Co tool inserts were used in the study. The feed and the depth of milling were maintained constant, and only the milling speed was varied because it is the most affecting parameter. Results showed that cutting force and tool life were greatly influenced by the contents of hydrogen. Tool life decreased at first and then increased gradually with the increase of hydrogen content, and the maximum magnitude decrease of tool life is about 0.2%H, meanwhile, the maximum tool life is about 0.5%H. However, with the increase of cutting speed, the favorable effect of hydrogen on the titanium alloy machinability would be weakened even disappear, therefore, 50-100m/min would be a suitable choice of cutting speed.

Work Material

This paper is the result of an analytical and experimental study of the effect of the physical properties of a material on its machinability. The physical properties studied were: the total stress-strain relations; the hardness; the microstructure; the abrasiveness; the thermal properties. A variety of ferrous and nonferrous materials were selected with a large range of the physical properties. A relationship is derived by means of which it is possible to calculate the culling speed for a given tool life from the physical properties of the work material.

In this paper, objective function for the highest productivity and longer life of the twist drill is built. Though using Materlab software to draw the curves of the changes of feed, spindle speed, tool life and productivity, a way to find the better cutting parameters of machining the small diameter deep hole on the SUS316 austenitic stainless steel with the twist drill is introduced. The better cutting parameters are obtained.
