Abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing, which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the ceramics which are used to cut, grind and polish other softer materials are known as abrasives.
Cutting tool or cutter is used to cut, shape, and remove material from a workpiece by means of machining tools as well as shear deformation. There are several different types of single edge cutting tools that are made from a variety of hardened metal alloys that are vary in size as well as alloy composition depending on the size and the type of material being turned. These cutting tools are held stationary by what is known as a tool post which is what manipulates the tools to cut the material into the desired shape.
Inspections ensure accuracy and standard. Inspection can be a visual inspection or involve sensing technologies such as ultrasonic testing, accomplished with a direct physical presence or remotely such as a remote visual inspection, and manually or automatically such as an automated optical inspection. Non-contact optical measurement and photogrammetry have become common NDT methods for inspection of manufactured components and design optimization.
Machining is a process in which a material (often metal) is cut to a desired final shape and size by a controlled material-removal process. The processes that have this common theme are collectively called subtractive manufacturing, which utilizes machine tools, in contrast to additive manufacturing (3D printing), which uses controlled addition of material.
Material testing is an interdisciplinary field of materials science that covers the discovery of new materials and characteristic, classify particularly solids. The field is also commonly termed materials science and engineering emphasizing engineering aspects of building useful items, and materials physics, which emphasizes the use of physics to describe material properties.
Metrology is defined by the International Bureau of Weights and Measures (BIPM) as "the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology". It establishes a common understanding of units, crucial to human activity. Metrology is a wide reaching field, but can be summarized through three basic activities: the definition of internationally accepted units of measurement, the realisation of these units of measurement in practice, and the application of chains of traceability (linking measurements to reference standards). These concepts apply in different degrees to metrology's three main fields: scientific metrology; applied, technical or industrial metrology, and legal metrology.
Overall maintenance functions can defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, and residential installations. Over time, this has come to include multiple wordings that describe various cost-effective practices to keep equipment operational; these activities occur either before or after a failure.
Sawing are commonly used for cutting hard materials. They are used extensively in forestry, construction, demolition, medicine, and hunting. saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. The cut is made by placing the toothed edge against the material and moving it forcefully forth and less vigorously back or continuously forward. This force may be applied by hand, or powered by steam, water, electricity or other power source. An abrasive saw has a powered circular blade designed to cut through metal or ceramic.

TOKYO – Mitsubishi Heavy Industries Ltd. dari Jepang berhasil meluncurkan roket membawa pengorbit Mars yang dikembangkan oleh ilmuwan muslim di Uni Emirat Arab pada Senin pagi.
Roket H2A yang membawa penjelajah Harapan lepas landas pada pukul 6:58 dari Pusat Antariksa Tanegashima di Prefektur Kagoshima, Jepang barat daya.
Foto yang diambil 20 Juli 2020 menunjukkan roket H2A yang lepas landas dari Tanegashima Space Center di Prefektur Kagoshima, Jepang barat daya, membawa unit satelit pengamatan pengorbit Mars yang dikembangkan oleh Uni Emirat Arab.
The Hope explorer atau Penjelajah Harapan, yang dikembangkan oleh ilmuwan muslim di Pusat Antariksa Mohammed bin Rashid di Dubai, diperkirakan akan menempuh jarak 493,5 juta kilometer selama tujuh bulan untuk mencapai orbit di sekitar Mars pada tahun 2021, menandai peringatan ke-50 berdirinya UEA. Ini akan menjadi misi antarplanet pertama dan satu-satunya oleh negara Timur Tengah.
Penjelajah, berukuran panjang 2,9 meter dan lebar 8 meter ketika panel surya sepenuhnya diperpanjang dan beratnya 1,5 ton, akan meneliti suhu dan kelembaban atmosfer Mars untuk mempelajari perubahan dalam periode yang panjang dalam iklim planet merah.
Satelit itu diperkirakan akan beroperasi diketinggian 20.000 hingga 40.000 km di atas Mars dan mengorbit planet ini setiap 55 jam.
Pengangkatan roket pengorbit Mars awalnya dijadwalkan untuk hari Rabu tetapi ditunda karena cuaca buruk di lokasi peluncuran.
Manajer proyek Pak Omran Sharaf mengatakan dalam konferensi pers online pada 13 Juli lalu bahwa penyelidikan itu merupakan upaya strategis untuk mendorong pengembangan sektor luar angkasa negara itu, berinvestasi dalam sumber daya yang dapat mengarah pada ekonomi baru di masa depan.
Dia juga menyatakan terima kasih atas dukungan Jepang terhadap proyek di tengah pandemi coronavirus.
Proyek terbaru adalah yang keempat di mana Mitsubishi Heavy Industries Jepang telah melakukan peluncuran untuk pelanggan luar negeri. Setelah sebelumnya, Mitsubishi juga telah bekerjasama membantu Korea Selatan pada 2012, Kanada pada 2015 dan UEA pada 2018.
Senin ini menandai peluncuran roket H2A ke-36 yang berhasil secara berturut-turut.

Siapa pun di industri manufaktur tahu bahwa kualitas produk mereka merupakan perwujudan dari kualitas kerja mereka sendiri. Meskipun selalu ada pergulatan konstan antara kualitas dan kuantitas, tidak ada alasan mengapa Anda tidak dapat memiliki proses manufaktur yang terbaik dari kedua hal tersebut.

Karena bencana alam, produk asal Taiwan bisa terkendala tak tentu, China & Jepang terkendala delay ±4 Minggu karena lead time logistik, harap maklum! ☹️ Tutup
