“…Hence, the difficult to machine materials are requiring new generation of cutting tools like CBN and PCBN owing to high temperature stability, hot hardness etc. Senthilkumar et al [2] turned hard martensitic stainless steel and found that it produced saw tooth chips in all operating parameters and similar chips were produced in turning hard stainless steel in the present research and no such formation in turning SCM 440 alloy steel. The formation of saw tooth chips is a complex phenomenon and no one reason responsible for the formation.…”

Hard turning technique is new and the management of this process is still limited. AISI 440 C martensitic stainless steel and SCM 440 are alloy steel used as work piece materials for this research work. The stainless steel is difficult to cut material, low thermal conductivity, tendency to form built up edges at tool edge and less corrosion resistant where as SCM 440 is high strength material. The flank wear formed on CBN by stainless steel was more than alloy steel. The crater wear formed on CBN tool while turning stainless steel than alloy steel. The chips produced by stainless steel were saw tooth form and SCM 440 alloy steel did not produce saw tooth chips. Flank wear and crater wear were caused by severe abrasion and also by high heat generated during turning on stainless steel. The flank wear and temperature also contributed on cutting forces on both materials, but very little on stainless steel and more on alloy steel.

“…The results showed that a longer life was obtained when using low cutting speed and low feed rates as well as when using inserts with finer grain size when turning titanium alloy under dry machining condition. Senthil et al 2006, evaluated tool life from a tool wear model when machining hardened martensitic stainless steel. Tamizharasan, et al 2006, studied the effect of the cutting parameters on tool life, tool wear and material removal.…”

Tool life is an important factor to be considered during the optimisation of a machining process since cutting parameters can be adjusted to optimise tool changing, reducing cost and time of production. Also the performance of a tool is directly linked to the generated surface roughness and this is important in cases where there are strict surface quality requirements. The prediction of tool life and the resulting surface roughness in milling operations has attracted considerable research efforts. The research reported herein is focused on defining the influence of milling cutting parameters such as cutting speed, feed rate and axial depth of cut, on three major tool performance parameters namely, tool life, material removal and surface roughness. The research is seeking to define methods that will allow the selection of optimal parameters for best tool performance when face milling 416 stainless steel bars. For this study the Taguchi method was applied in a special design of an orthogonal array that allows studying the entire parameter space with only a number of experiments representing savings in cost and time of experiments. The findings were that the cutting speed has the most influence on tool life and surface roughness and very limited influence on material removal. By last tool life can be judged either from tool life or volume of material removal.

“…The turning of work material also produced saw tooth chips in all operating parameters which is shown in the Figure 5 (a). Senthilkumar et al [14] turned hard martensitic stainless steel and found that it produced saw tooth chips in all operating parameters. In this experiment, it was true that chips produced were saw tooth.…”

Hard turning of materials is a process where dimensional accuracies, dimensional controls and surface roughness are easily obtained. Currently hard components are produced by hard machining in a very short time which also saves on cost. Martensitic stainless steel is difficult to cut due to the presence of high amount of chromium and makes the material harder. AISI 440 C hardness is maintained through induction hardening process. The cutting tool used for this material is normally a super hard cutting tool like CBN and PCBN tools and less tool wear is possible. Minimising tool wear is the main criteria of the machining process. The influence of flank wear was due to abrasive action of hard martensitic carbides of the work material at low cutting speed, and low feed rate. The crater wear also formed and was due to abrasive action of the saw tooth chips and also by heat at cutting zone. Saw tooth chips were produced by while machining martensitic stainless steel and the rough surface of the chips responsible for occurrence of the crater wear.
