“…From the surface roughness test that has been carried out and the graph above, it can be concluded that the higher the spindle speed used, the lower the surface roughness level, and the slower the spindle speed used, the higher the surface roughness level. These results are in accordance with research conducted by Kaisan [11]: the higher the spindle speed, the lower the roughness produced because the higher the spindle rotation, the greater the machine's effort to cut the workpiece so that the surface roughness will be low. As for the use of the zig-zag type of cutting direction, the roughness value is lower than that of the oneway type.…”

CNC Milling machine is a machine that is widely used for the manufacture of a component. Product quality will be related to product selling value and consumer satisfaction, therefore the best parameters must be known in order to produce quality products. This study aims to determine the effect of the cutting direction on the structure and surface roughness of the pocket feeding CNC Milling machining process. Experimental methods are used to improve the quality of products produced by CNC Milling machines. The parameters used in this study are variations of spindle speed 500 rpm, 1900 rpm, and 5000 rpm, as well as variations of cutting direction, namely one way and zig-zag. The tests carried out are in the form of surface roughness testing, micro-structure observations, and macro-structures. The data analysis technique used is descriptive statistics. The results obtained are the use of the cutting direction parameter affects the quality of the resulting product in the form of structure and surface roughness. The zig-zag cutting direction parameter with spindle speed 5000 rpm obtained the lowest average surface roughness value of 0.87 Î¼m, while the one way cutting direction with spindle speed 500 rpm obtained the highest average roughness value of 2,84 Î¼m. In conclusion, using a higher spindle speed will result in a lower roughness value, while the zig-zag cutting direction produces a lower roughness value and a more even surface structure compared to one way cutting direction.

Testing the effect of distance and laser beam heat on engraving results using two specimens as test materials, namely teak wood and durian wood. The testing process is to make circles and rectangles with a diameter of 20 mm which are inputted into the program followed by the engraving process. The results of the engraving are measured how many differences occur so that the results that are closest to the level of precision are obtained with variations in distance and heat in the laser beam. From the results of the distance test, it was found that durian wood has a more precise engraving accuracy with a size of 0.15-0.35mm, while for teak wood with a size of 0.2-0.4mm. With reference to the general tolerance of medium in sizes >6-30mm is 0.2mm, the best result for the use of spacing is 70mm. From the results of laser heat testing, it was found that durian wood has a more precise engraving accuracy with a size of 0.05 - 0.7mm, while for teak wood with a size of 0.1-0.8mm. With reference to the general tolerance of medium in size >6-30mm is 0.2mm and size >30-120mm is 0.3mm, the best temperature result for use is 400C with a tolerance size of 0.05mm.

The Research was about the comparison between experiment and simulation of natural frequency in CNC spindle. CNC spindle vibration will reduce machine tool performance. It could lead to the damage of the machine tool. The spindle structure unbalances of machine tools will cause vibration when it is operated. In the CNC machine, the spindle shaft vibration should be minimum. Based on this point, the natural frequency testing on the spindle shaft structure was carried out. The experiments were conducted by employing oscilloscope which could provide the vibration data in the time domain. The data was converted into the frequency domain using FFT. Measurements were carried out on 7 times of testing. Every one time of testing, 10 data were taken at each testing points. The tests were conducted at 10 testing points. Therefore, the total data obtained were 700 test data. The test results were then compared with the results of simulation modeling in 10 vibrate modes using Solidwork software. After testing and simulations were compared, 4 personal frequency values were obtained in the test that uses a measuring instrument and 6 personal frequency values could not be read. These were because the accelerometer used could not read up to 0 Hz frequency. Natural frequency obtained from simulations and tests were expressed in the percentage of errors. The largest error value in the 9th vibration mode measurement with a natural frequency was 2117.96 Hz with an error of 0.32%. The smallest error value was 0.11% with a natural frequency of 2995.79 Hz.
