This study investigated the effects of the die clearance on the shearing and shaving processes of the stainless steel (SUS316LVM) wire at micro scale. A die set was developed and installed on a precession press equipped with a load cell and a displacement sensor to conduct experiments. By using different punches in the same die set, the specimens prepared from 316LVM stainless steel wires with 0.5 mm diameter were first sheared and then shaved. Experimental results show that the burnished area of the sheared edge increases with the reduction of the clearance between the punch and die in the shearing process. The clearance also significantly affects the load curves. Moreover, the shaving process does increase the burnished area on the shaved edge of the specimen. By an appropriate feed in the shaving process, it is possible to trim the extra material from the sheared edge that results in a nearly complete burnished surface on the shaved edge of the stainless steel wire. This research provides a basis for understanding of the die clearance effect on the shearing and shaving processes at micro scale.

Measurement Capabilities

Reliable measurements of thrust from systems to be flown on satellites are essential to ensure repeatable maneuvering capability of small nanosatellites. Thrusters can be used to vary spacecraft orientation, detumbling, and orbit change. Tests have been conducted in a low-pressure vacuum system using a cold gas prototype thruster and two independently calibrated methods: a four-point pendulum with a laser interferometer displacement sensor and a load cell, both of which have measurement capabilities from tens of micronewtons to tens of millinewtons. The agreement is very good, lending confidence in both methods. The advantages and disadvantages of both methods will be discussed. They include absolute accuracy, low thrust accuracy, temporal resolution, simplicity of operation, cost, and sensitivity to vibrations generated by laboratory equipment such as pumps, fans, bumps, and human movement.

Module System

This study aims to create a system that can monitor gas cylinders where this device consists of two systems, the first is a system to measure the weight of 3kg LPG gas cylinders to find the remaining gas which will then be displayed on the LCD, and the second the system gives a notification (alarm) if there is a gas leak via SMS. This system consists of Arduino UNO Microcontroller components, Load cell Sensor, MQ-6 Sensor, and SIM800L GSM Module. For overall system testing, the load cell sensor system can display a percentage of the weight value obtained an error rate of 0%, this indicates that the formula used in the program runs according to what is desired. In the MQ-6 sensor system can make the buzzer on at a value >= 700 ppm, the results of the buzzer can live when the detected gas value >= 700 ppm, this is as desired. In the sim800L gsm module system can send leak notifications, the results obtained that the module can send SMS notifications. And the system turns on the buzzer when the LPG gas has reached the minimum limit, the results obtained by the buzzer will sound when the remaining gas value <= 16%. Based on tests conducted on this system the system can measure the desired weight of the cylinder to look for the remaining gas in the form of a percentage and detect a gas leak and then send an SMS notification.

Kebutuhan manusia semakin lama semakin meningkat, berkembang dan bervariasi, untuk memenuhi kebutuhan tersebut industri membutuhkan suatu alat yang dapat mengontrol dan mengendalikan proses permesinan secara otomatis. Diantaranya industri yang memerlukan pengendalian kualitas secara otomatis adalah industri makanan dan minuman instan. Di Indonesia, industri minuman didominasi oleh hasil olahan minuman instan bubuk dan cair. Salah satunya minuman instan kopi, minuman kopi membutuhkan beberapa tahap pengolahan, salah satu yang terpenting adalah proses pemutuan biji kopi. Saat ini industri masih menggunakan tenaga konvensional yang memakan waktu, biaya, tenaga operator. Penentuan mutu dengan cara seperti ini mempunyai kelemahan dari sisi subyektivitas yang memungkinkan terjadinya kesalahan akibat kelelahan mata manusia terhadap contoh yang dianalisis. Untuk menanggulangi masalah tersebut perlu adanya mesin pemutuan biji kopi dengan sistem otomasi berdasarkan parameter besar dan kecilnya biji kopi. Dengan cara menghitung banyaknya biji kopi pada sampel 300 gram biji kopi. Penyelesaian rancang bangun ini dilakukan dengan 2 tahapan yaitu perancangan konveyor sabuk dan perancangan otomasi. Perancangan konveyor sabuk pemilah terdiri dari pemilihan konsep, desain rinci menggunakan aplikasi Solidwork dan proses pembuatan berdasarkan desain. Selanjutnya, perancangan otomasi menggunakan mikrokontroller Arduino Uno, sensor load cell dan sensor FC-51. Setelah peralatan sudah dipasang semua selanjutnya dilakukan pengujian didapatkan dari 300 gram biji kopi terhitung jumlah biji kopi yang bervariasi yaitu 907, 954, 976, 1007, dan 1036 biji kopi. Kemudian, ketinggian sensor yang optimal 6 cm dari permukaan belt conveyor dan kecepatan conveyor 1,52 m/menit agar pembacaan sensor FC-51 akurat.

Stator Design

A piezoelectric actuator using a lever mechanism is designed, fabricated, and tested with the aim of accomplishing long-travel precision linear driving based on the stick-slip principle. The proposed actuator mainly consists of a stator, an adjustment mechanism, a preload mechanism, a base, and a linear guide. The stator design, comprising a piezoelectric stack and a lever mechanism with a long hinge used to increase the displacement of the driving foot, is described. A simplified model of the stator is created. Its design parameters are determined by an analytical model and confirmed using the finite element method. In a series of experiments, a laser displacement sensor is employed to measure the displacement responses of the actuator under the application of different driving signals. The experiment results demonstrate that the velocity of the actuator rises from 0.05 mm/s to 1.8 mm/s with the frequency increasing from 30 Hz to 150 Hz and the voltage increasing from 30 V to 150 V. It is shown that the minimum step distance of the actuator is 0.875 μm. The proposed actuator features large stroke, a simple structure, fast response, and high resolution.
