Abstract

Filter in this research is interpreted as screening of undesirable frequency component in order to depressed it as small as possible to produce the changes of magnitude of response signal. The filtered vibration signal is in a form of the Random Signal Excitation which is generated in MATLAB Version 6.5. The signal is filtered by using Filter Chebyshev Type II. Simulation conducted repeatedly from 10 to 100 times excitation. Magnitude of Response Filter is obtained after simulation. Result is compared to its initial and expressed in the form of different percentage of magnitude between the mean of Magnitude of Response Filter because of applying Random Excitation Signal to the Excitation of Signal Impact from 10 to 100 times. Maximum different percentage of highest magnitude occurred in the simulation of 10 times excitation (57%). While the Minimum occurred in the simulation of 50 times (32%).

Abstract

This research was aimed to optimize a lathing cost by varying the cutting speed and cutting depth. A test was perfomed on 27 steel shaft AISI-1040 test objects with diameter of 25 mm and 150 mm long each, in order to obtain the optimum cutting time and cost in a lathing process. It was found that higher the cutting speed, the lower the total production cost, while the cutting depth does not affect the total production cost. The optimum average machining time is 3.153 minute/test object and the lowest total production cost is Rp.5,653/test object. The optimization made the target to minimize the total production cost was reached in cutting speed of 1600 rpm and cutting depth of 1,00 mm, with total production cost of the lathing process of the 27 test objects as much as Rp.16,960 Keyword: Optimization, Lathe, Cutting time, Production cost

ABSTRACT Filter in this research is interpreted as screening of undesirable frequency component. In this research, the highest different percentage of magnitude for the 15, 30, 45 until 150 times of excitation can be obtained. The impact excitation signal and the random excitation signal were develop using Matlab version 6.5. The random and impact signal then filtered using Butterworth filter. The excitation of random signal was develop using Matlab version 6.5. The simulation of random signal was proceed repeatedly over 15, 30, 45 until 150 times of excitation. The simulation resulted the average numbers of filter magnitude response. Which is then compared with the impact excitation signal indicated by percentage difference. Based on the results of simulation and calculation the maximum different percentage of highest magnitude occurred in the simulation of 15 times excitation (50%). The chart of the different percentage of highest magnitude tend to be flat at the 60 times until 150 times of excitation. While the average numbers of filter magnitude response due to the random signal excitation can not be considered as same as the numbers of filter magnitude response due to the impact signal, because the difference is above 5%.
