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.

MITUTOYO Rockwell hardness testing machines HR-210MR Series 963-220D merupakan Hardness tester skala Rockwell yang paling terjangkau. Mesin penguji kekerasan material logam dari Mitutoyo ini memungkinkan pengukuran Skala Rockwell didasarkan pada kekerasan lekukan material dengan kedalaman penetrasi indentor di bawah beban besar (beban utama) dibandingkan dengan penetrasi yang dibuat oleh preload (beban kecil). Rangka dan desain yang sangat stabil dilengkapi dengan coating pelindung panas untuk menjaga akurasi selama sesi pengukuran yang berulang-ulang.
Setiap seri hardness tester MITUTOYO Rockwell hardness testing machines HR-210MR Series 963-220D telah dirancang untuk akurasi, keandalan, dan daya tahan dengan harga yang terjangkau. Instrumen-instrumen ini menawarkan akurasi dalam mengukur ketangguhan suatu material dan jumlah maksimum energi yang dapat diserapnya sebelum penyok maupun patah berlubang. Hardness tester ini tersedia dengan tampilan analog dial dengan operasi beban identer secara manual (dengan total gaya uji dipilih) dan penanganan gaya uji pendahuluan.
