Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

The first purpose of this study is to assess the influence of cutting mode parameters on surface roughness and tool wear. The second purpose of this study is to build a relationship between surface roughness and tool wear. The cutting parameters mentioned in this study include the cutting speed, the feed rate and the depth of cut. The experimental material used in this study is steel C45. The cutting tool used is the PVD-coated face milling cutter. Experiment with 15 experimental points according to the Box-Behnken type experiment plan when changing the value of the cutting parameters. Analysis of test results has determined the influence of cutting parameters and their interaction on surface roughness and tool wear. The relationship between surface roughness and cutting parameters, the relationship between tool wear and cutting parameters and the relationship between surface roughness and tool wear are also established in this study. These relationships are the basis for defining cutting parameters to ensure that the surface roughness meets the specific requirement, the tool wear is small, and are the basis for determining when to replace (re-sharpen) the tool according to the specific surface roughness requirements
This work presents a comprehensive study of the dynamic simulation and analysis of synchronous motor with field excitation. The dynamic model of the synchronous motor with damper windings was derived by the equations of the coupled stator and rotor circuits together with the mechanical equations of motion of the rotor. The Park’s Transformation approach was employed with the reference frame fixed in the rotor. The mathematical model of the motor was examined under two loading conditions: step and ramp loading. The excitation voltage was constant at 50V for both conditions. The simulation was run for 6 seconds; the motor parameters were plotted against time. At 4 seconds, a step load of 150Nm and ramp load starting from 100Nm was applied under both loading conditions. The performances of the synchronous motor were observed during the starting, steady state and ramp loading conditions of the motor. At no load motor attains steady state at 3 seconds with overshoots at startup, at loading conditions the motor showed quick response in damping out transients due to sudden load input. The motor pulled out of synchronism at maximum torque of 210Nm under ramp conditions. It was observed that field excitation varied proportionally to pullout torque and load current. Simulations were carried out using Embedded MATLAB/Simulink tool box in MATLAB software
