Abstract

In today highly sophisticated manufacturing industry, of course,the best product results are needed. Machining work, especially on CNC turning machining needs to be considered roughness level. The lower the roughness level,  the better the workmanship will be. For this reason it is necessary to pay attention to the parameters used so that the roughness of the product is getting lower. This study aims to determine the best parameters. The machining process is carried out on the MORI SEIKI SL-25B/500 CNC turning and S45C material. Parameters used consist of  feed motion, feed thickness, and spindle speed. The experimental design was based on the taguchimethod with an orthogonal L9(33) matrix and 2 times of replication as a comparison, there was no significant deviation. From the research, the contribution of feeding motion is 49,734%, feeding thickness is 19,239%, and spindle speed is 7,334%. The smallest roughness in the MORI SEIKI SL25B/500 CNC turning machining process was obtained from setting the feed motion 0.2 mm/rev, feeding thickness 1 mm, and spindle speed 2000 rev/minute.

Abstract

Based on direct observation with partners, the problems faced are that in the process of drying the oil of cassava chips, they still use manual methods by drying them on a container for 15 minutes with the amount of cassava chips dried as much as 2 kg and this manual process still leaves oil on the cassava chips until they are marketed which in the future will make the cassava chips quickly unfit for consumption. The problem faced by the cassava chip business partner “Cahaya Bangka” is that they cannot be stored longer / not durable. The expected benefits of the partner can increase the amount of production, faster production time, and also produce more products and last longer/durable. The influence on sales is quite large because buyers are not brave enough to buy cassava chips in large quantities. The solution given to partners is to utilize a cassava chip oil dryer machine with the implementation method of providing short training on the operation and maintenance of the cassava chip oil dryer machine so that partners understand how to use and maintain the machine properly and correctly. With the cassava chip oil dryer machine, the drying process of cassava chips with a total of 10 kg of cassava chips in 4 minutes can increase the amount of production, the production process time becomes faster and the cassava chips become more durable than before.

Abstract

The rate of transportation development in Indonesia faces a significant increase. However, the increase in transportation rates is not in line with the increase in residents, especially for people with disabilities. One form of discrimination against people with disabilities is the lack of accessible transportation equipment for wheelchair users. The lack of service facilities makes people with disabilities feel insecure. The lack of facilities provided makes people with disabilities choose to use individual vehicles to continue activities like normal people. The purpose of the research on providing transportation facilities for people with leg disabilities is very much needed in carrying out daily activities easily and without obstacles. The design of a wheelchair user disability vehicle uses the VDI 2222 design method with 4 stages, namely planning, conceptualizing, designing, and completing. From the conceptualization session, 3 design concept variations were generated which were then assessed based on technical and economical aspects. From the test results that were tested, the average speed that can be reached by this wheelchair user disability vehicle is 30 kilometers / hour.

Abstract

In production machining process is something that must be prioritized. One factor that affects the quality of production is the condition of the machine tool. The Mori Seiki SL 25 CNC Turning Machine is a machine that has existed since 1998 at the Polman Babel Mechanic Workshop and has been used for production processes and learning facilities for approximately 25 years. The use of machine tools at that time can affect the machine's geometric conditions, affecting the quality of the product produced. Roundness is one of these geometric conditions because many components with round cross-sections affect the components' function if deviations occur. Deviations in the roundness value on the machine can be known by testing the roundness value of the machining workpiece. From these tests, geometric errors in the machine and the feasibility of the machine in processing workpieces at specific size tolerances can be seen. The workpiece resulting from the machining process will be measured for its roundness value and then analyzed using the Minimum Zone Center (MZC) method. The test results on the geometric conditions of the machine are that the highest roundness deviation is at position 1 with an average of 21.7 μm which is the outermost position of the clamping area. The slightest deviation value is at position 6 with an average of 10.9 μm, and the machine can produce workpieces with a tolerance above 21 μm.

Abstract

In this era of increasingly advanced industrial technology development, of course, everyone wants the best results in making a product. For example in the machining process, one of which is CNC lathe machining, the level of roughness of a product really needs to be reviewed. The minimum surface roughness shows that the quality of a CNC machining process is very good, because the smaller the surface roughness value, the greater the quality value of a product, therefore in order to achieve this goal it is necessary to set the right parameters. Parameters varied were spindle speed (Rpm) and feeding. In this study the method used is the experimental method, with a combination of parameters to obtain surface roughness values. The material used is AISI 1045 steel, with the results of the data being analyzed using the Taguchi Smaller the Better method in Minitab 21.3 software. From the results of the calculation of the mean factor, the percent contribution to the spindle speed was obtained at 56.28%, while at feeding it was obtained at 38.14%. The optimal roughness value is obtained from the combination of parameters in the CNC lathe process on AISI 1045 steel which can make the optimal response value obtained at a spindle speed of 1645 rpm and a feeding of 0.18 mm/rev.

So that the manufacturing industry is required to be able to produce quality products and a high level of accuracy with fast processing. One machine that can meet these demands is a CNC lathe, where a CNC lathe is a machine that is controlled using a computer system in its operation. In the machining process of CNC lathes, the level of surface roughness of the machining material is of great concern, because the lower the surface roughness value, the better the quality of the product. Therefore, the aim of this study was to obtain a low surface roughness value using a finishing cutting edge. The material used is AISI 1045 steel which is turned using a MORI SEIKI SL-25 CNC machine. The parameters used are spindle speed and feeding. The research method used was the Taguchi method with an orthogonal matrix L9(32) experimental design and 3 replications were carried out to reduce large deviations. The result of this research is to obtain a combination of parameters that produce minimum surface roughness values, namely spindle speed of 1804 rpm and feeding of 0.1 mm/put. And the parameter that has the greatest effect on the value of roughness is feeding with a difference of 16.029 and the one that has the least effect on the value of surface roughness is spindle speed with a difference of 1.384.

Abstract

Times are growing rapidly. One of them is marked by the development of technology that facilitates human work, for example CNC lathes. In the machining process, a CNC lathe produces a surface roughness value. The smaller the surface roughness value, the better. The tool for measuring surface roughness is the Surface Roughness Tester. The purpose of this study was to obtain the surface roughness value of the dry and wet feed machining processes or by using a cooling medium and not using a cooling medium, namely drromus, which then obtained the best results from the two feeding processes. The method used is the Taguchi method developed by Genichi Taguchi where this method is used to improve the quality of production results from the manufacturing process. The results of the surface roughness research obtained for wet food from 3 repetitions on average were 2.068, 1.233, 1.621 and 1.253. And the yield values for dry food processing are 1.670, 0.987, 1.146 and 1.679. The conclusion obtained is that the smallest roughness value in the wet feeding process is 1.233 with parameters RPM 1273.88, Deft Of Cut 1mm, and Feeding 0.16 mm/put. And for dry feeding it is 0.987 with parameters RPM 1273.88, Deft Of Cut 1mm, and Feeding 0.16 mm/put.

Abstract

A high material removal rate is one of the goals to be achieved when machining parts with CNC turning. However, slow processing affects product processing time and increases production costs. To overcome this problem, it is necessary to set the correct process parameters so that they provide the most influential contribution to the MRR and produce maximum parameter values. This research aims to determine the influence of parameters (spindle speed, feed speed, and feed depth) on MRR and to determine the correct process parameter settings to produce maximum MRR, namely in this experimental design using an orthogonal array L9 (33) with three replications. The material used is ST-60 steel, with the data analyzed using the Taguchi Larger Is a Better method in analysis software. From the results of the mean factor calculation, the percent contribution to feeding was found to be 19.53%, while the depth of feeding was found to be 64.56%. The optimum MRR value is obtained from a combination of parameters in the CNC Turning process on ST-60 steel which can make the response value optimally obtained at the spindle speed 3,184 [rev/min], feeding 0.22 [mm/rev] and depth of cut 2.5 [mm].
