Drilling process is one of the most common machning process in industrial sector. More than half of the metal-cutting processes are conducted by the drilling process. Drill bit has influenced the results of the drilling process. Therefore, selection of the suitable drill bit becomes a critical factor in the drilling process. This is because the use of the suitable drill bit could fulfill the determined specification value of the hole. Six Sigma and Failure Mode Effect Analysis (FMEA) methods are used to identify factors that have influenced the results of the drilling process. Then by using the Design of Experiment, selection of the best drill bit could be done. In this study, 2 factors that influenced the result are the drill bit type and the drill point angle. Significance test using nested design through MINITAB 14 application has shown that both factors have significant influence over the hole diameter size.. Then by using the plot from the MINITAB 14 application, HPMT 1 became the best drill bit because it could fulfill the specification value. As for the best point angle in this study is 139.72º. Process capability calculation of HPMT 1 has shown that the process is in control. The conclusion is that drill bit HPMT 1 with point angle 139.72º became the best option in this study.

This paper uses a metal cutting simulation software AdvantEdge FEM as the platform, and simulates the drilling process of three different honed cutting edge K-Grade carbide drills. The aim is to study the influence of different magnitude of honed cutting edge on the the cutting force and torque. According to the simulation, the z-axis force and torque increase while the margin of the fluctuation decrease with the honed edge radius increase. In this paper, the z-axis force and torque reach the maximum and the margin of fluctuation in the smallest when using the honed edge radius of 0.10mm.

This paper uses a metal cutting simulation software AdvantEdge FEM as the platform, and simulates the drilling process of 42CrMo with three different honed cutting edge K-Grade carbide drills. The aim is to study the influence of different magnitude of honed cutting edge on the maximum temperature of cutting area. According to the simulation, the maximum temperature does not absolutely increase with the honed edge radius increase. The cutting temperature reaches maximum when the honed edge radius is 0.06mm in this paper, meanwhile the margin of fluctuation in the smallest.

By modeling cutting processes in the ANSYS and DEFORM software environments, can significantly reduce costs when choosing rational tool material for metal-cutting tool. For multilayer coatings on carbide substrate this is difficult for number of reasons. This possibility is shown and examples for using of the DEFORM software environment for choosing of rational or competing coatings, including for “designing” of the coating for the specified operating conditions of metal-cutting tool are presented.

High Efficiency Deep Grinding (HEDG) has been known to secure high removal rates in grinding processes at high wheel speed, relatively large depth of cut and moderately high work speed. High removal rates in HEDG are associated with very efficient grinding and secure very low specific energy comparable to conventional cutting processes. Though there exist HEDG-enabled machine tools, the wide spread of HEDG has been very limited due to the requirement for the machine tool and process design to ensure workpiece surface integrity. HEDG is an aggressive machining process that requires an adequate selection of grinding parameters in order to be successful within a given machine tool and workpiece configuration. This paper presents progress made in the development of a specialised HEDG machine. Results of HEDG processes obtained from the designed machine tool are presented to illustrate achievable high specific removal rates. Specific grinding energies are shown alongside with measured contact arc temperatures. An enhanced single-pole thermocouple technique was used to measure the actual contact temperatures in deep cutting. The performance of conventional wheels is depicted together with the performance of a CBN wheel obtained from actual industrial tests.
