Abstrak Sebelum petani Subak mengenal traktor, pengolahan tanah dilakukan dengan menggunakan cangkul atau bajak singkal yang ditarik oleh ternak. Pengolahan tanah dengan traktor yang dilengkapi dengan komplemen bajak singkal atau bajak rotari tidak dapat dihindari terjadinya kasus tumpang tindih (overlap) hasil pengolahan, sehingga hasil tanah olahan menjadi tidak efisien. Tumpang tindihnya hasil pengolahan tersebut terlihat dari perbedaan hasil tanah yang diolah.

Turning with rotary tool is a newly developed alternative of the conventional turning process in which cutting edge of a round insert rotates about its axis, so that a continuously indexed cutting edge is fed into the cutting zone. In the present study, a longitudinal high-frequency vibration was superimposed to the rotary tool to analyze the cutting force and surface roughness of AA7075 during orthogonal cutting. However, due to contribution of wide ranges of factors in the vibratory-rotary turning process, the selection of optimal parameter setting is a challenge that is faced with this proc

Demand for organic food products has consistently increased for more than 20 yr. The largest obstacle to organic soybean production in the southeastern United States is weed management. Current organic soybean production relies on mechanical weed control, including multiple postplant rotary hoe uses. Although postplant rotary hoe use is effective at the weed germination stage, its efficacy is severely compromised by delays due to weather. Preplant rotary hoeing is also a practice that has been utilized for weed control but the effectiveness of this practice to reduce the need for multiple post

Rotary forging process has recently been developed in which the material is deformed partially and incrementally and a deformation zone is developed and swept through the material. Since the upper die in rotary forging is always in contact with the workpiece top surface, and presses continuously the workpiece until it takes the final shape in one stroke (i.e. resembling conventional press forging), it might be more definite to name it as rotary press forging. Rotary press forging produces many defects. The author has invented a process, namely, rotary hammer forging, which reduces these defect

Abstrak CV.Karya Purabaya merupakan perusahaan pengolahan kayu lapis (plywood). Rotary machine adalah salah satu mesin yang sangat berpotensi mengalami kegagalan produksi. Kerusakan pada instrumentasi rotary machine biasa disebabkan oleh komponen dari instrumentasi rotary machine itu sendiri. Pada tahun 2021 Rotary Machine mengalami kerusakan sebanyak 65 kali. Tujuan penelitian ialah melakukan identifikasi masalah, studi literature, pengumpulan data, pengolahan data, analisa pemecahan masalah, analisa FMEA, penentuan tindakan, penilaian keandalan, diagram pareto, kesimpulan dan saran.

ABSTRAKPembuatan semen terdiri dari beberapa tahap yaitu penambangan dan penyiapan bahan baku, pengeringan dan penggilingan bahan baku, pembakaran dan penggilingan akhir. Pengeringan dan penggilingan bahan baku dilakukan di raw mill unit. Proses ini penting dilakukan untuk mengurangi beban pada burning unit dan finish mill unit. Pada penelitian ini digunakan rotary dryer sebagai alat pengering bahan baku, kemudian grinding mill sebagai alat penggilingan dan pengeringan bahan baku. Rotary dryer berfungsi untuk menghilangkan/mengurangi kadar air sandy clay sebelum masuk grinding mill. Penelitian

Abstract:

A new hybrid rotary platform with three degrees of freedom that possesses both a large workspace and the ability to bear heavy loads is presented. The degrees of freedom and rotary characteristics of the hybrid rotary platform are analyzed, and its solution of inverse position is obtained. The dimensional optimization, structural design, and prototype development of the hybrid rotary platform were carried out, an electrical control system based on a multi-axis motion controller and a three-axis gyroscope was developed, and a calibration experiment on the hybrid rotary platform was performed.

Abstract:

This paper proposes a calibration method for angular positioning deviation of a high-precision rotary table based on the laser tracer multi-station measurement system. The algorithm error of the calibration method for angular positioning deviation of a high-precision rotary table based on the laser tracer multi-station measurement system was mainly discussed. During the experiments, the laser tracer was fixed on the work surface of the rotary table, and the rotary was fixed on the work surface of the coordinate measurement machine (CMM). The rotary table was rotated with the same angular inter

Abstract:

The aim of the study is to find the rotary instrument usage and preferred brand of rotary instrument among endodontists working in dental colleges, Chennai. A rotary instrument is used to remove or reduce tooth matter and to shape teeth during endodontic procedure. Rotary instrument includes burs and endodontic files. Various brands of rotary instruments are currently available in the market which includes dentsply protaper, Mtwo, endostar, k3 XF files, Heroshaper etc. The choice of rotary instrument by a dentist is governed by various factors like their efficiency, ductility, sharpness, cross
