Abstract

Pantiaw is one of the traditional dish made from rice flour served with fish meat grinder and other ingredients. The design of this pantiaw cutting tool uses a press system using a lever. Based on the survey that has been done at the residence of mrs. Yuli, pantiaw produce 8 kg daily. The obstacle faced by yulimother at this time is the process of cutting pantiaw still using scissors or knives sliced one by one. So that takes longer time is 45 minutes to 1 hour. The purpose of making this pantiaw cutting tool is to cut the pantiaw uniformly in a single process, increasing the production capacity and the tool is easy to movearound. The results of the pantiaw cutter test resulted in uniform pieces of pantiaw in one press / process. Capacity 0.5 kg pantiaw processing with 30 seconds.

Abstract

Vehicle Comfortability in a minibus is highly influenced by the noise level and the mechanical vibration on the cabin. Sound and vibration can come from the engine excitation, the pressure difference in both inside and outside of the cabin, the road roughness and the primary vehicle’s structure. The ground, wall and floor of the cabin in a vehicle are the most influenced parts in the role of transmitting sounds and vibrations. These can be reduced by means of increasing the cabin’s stiffness. Sheet metal is mainly used as the cabin’s material. Its stiffness can also be increased by means of thickening, grooving and embossing the plate. The aims of this experimental work are to increase both the natural frequency and the stiffness of the plate by means of forming and grooving in the cabin’s plate. The material used in this paper is mild steel plate 0,8 mm from galvanized steel that is generally used in manufacturing of the minibus vehicle (ASTM A 29 coated with zinc and aluminum). The research method is derived as follows: determining the panel dimension, calculating the number of the groove, designing both the heating temperature and the cooling media, grooving process, measuring and analyzing the natural frequency and the stiffness. The length and the width of the panel dimension are determined by 550 mm and 550 mm, respectively. Trapezium cross-section is used as groove’s design. The results show that the natural frequency and the stiffness are linearly influenced by residual stress. The highest frequency, reached at 258,06 Hz, is to be found at 10 groove with temperature of 700 °C and followed by water cooling. In addition, this frequency is increased nine times compared with plain panel without groove in which it has 27,55 Hz. Keywords: natural frequency, vehicle panel, heat treatment, fixed-end, stiffness

Abstract

In this design, the product we want to make is a die for the M 20 ring because the die we designed is helpful for student learning (practicum) at the Mechanical Technology Laboratory. The ring manufacturing process is carried out using one blanking compound dies. The blanking and piercing processes are carried out in one operation, thus saving time and money. This dies planning includes the process of designing dimensions and other supporting tools using the SolidWorks 2017 application. This design aims to produce blanking compound dies designs on press machines for the M20 ring manufacturing process with little or no defects and estimate the cost of making blanking compound dies. The method of analysis using Solidworks 2017 software includes displacement, von misses stress, safety factor. The results obtained from the 2017 SolidWorks analysis are to estimate the wear life of the punch and die to anticipate product failures. The material used in this ring is SAPH440 as defined in JIS 3113, starting from 2 mm to 14 mm. At the same time, the one we use for the M20 ring has a thickness of 2 mm. Based on the dies design calculations and data analysis that has been carried out, it is concluded that the use of blanking compound dies can reduce product defects due to dimensional accuracy in the dies and accelerate the production process of ring making.

Abstract

Salah satu kualitas yang terbaik dari suatu komponen adalah permukaan yang halus. Proses kerja mesin yang ingin dicapai pada bubut CNC Mori Seiki SL-25 adalah nilai kekasaran permukaan yang minimum, perlu dilakukan penentuan penyetelan yang tepat dari parameter-parameter proses bubut CNC Mori Seiki SL-25 agar diperoleh kekasaran permukaan benda yang minimum. Parameter proses pemesinan yang divariasikan adalah kecepatanNspindle, kedalaman pemakanan, dan kecepatannpemakanan. Tujuan dari penelitian ini adalah untuk mengetahui apakah ada pengaruh kecepatan spindle dan kedalamanNpemakanan terhadap tingkat kekasaran permukaan hasil pemesinan bubut CNC pada baja ST41. Metode yang digunakan dalam penelitian ini adalah metodeneksperimen, dengan penyetelan parameter untuk mendapat kekasaran permukaan. Baja yang digunakan adalah ST 41, dan data penelitian dianalisis menggunakan anova pada softwarenstatistik. Kesimpulan dari hasilnpenelitian menunjukkan persen kontribusi dari variabel-variabel adalah kecepatan spindle sebesar 27,79%, kedalaman pemakanan sebesar 7,28% dan kecepatan pemakanan sebesar 7,28%. Dari hasil analisa, kombinasi variabel padanprosesnbubut St41 yang dapat menghasilkan nilai respon paling optimal adalah kecepatan spindle sebesar 1526 rpm,. kedalaman pemakanannsebesar 0,6  mm, dan kecepatannpemakanan 0,25 mm/rev.
