Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches.
Computer-aided design (CAD) is the use of computers to aid in the creation, modification, analysis, or optimization of a design. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Designs made through CAD software are helpful in protecting products and inventions when used in patent applications. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The terms computer-aided drafting (CAD) and computer aided design and drafting (CADD) are also used.
Computer-aided manufacturing (CAM) also known as computer-aided modeling or computer-aided machining is the use of software to control machine tools in the manufacturing of work pieces. This is not the only definition for CAM, but it is the most common. It may also refer to the use of a computer to assist in all operations of a manufacturing plant, including planning, management, transportation and storage. Its primary purpose is to create a faster production process and components and tooling with more precise dimensions and material consistency, which in some cases, uses only the required amount of raw material, while simultaneously reducing energy consumption. CAM is now a system used in schools and lower educational purposes. CAM is a subsequent computer-aided process after computer-aided design (CAD) and sometimes computer-aided engineering (CAE), as the model generated in CAD and verified in CAE can be input into CAM software, which then controls the machine tool. CAM is used in many schools alongside computer-aided design (CAD) to create objects.
The National Physical Laboratory (NPL) is the national measurement standards laboratory of the United Kingdom. It sets and maintains physical standards for British industry.
A machinist is a tradesperson or trained professional who operates machine tools, and has the ability to set up tools such as milling machines, grinders, lathes, and drilling machines.
G-code is the most widely-used computer numerical control (CNC) programming language. It is used mainly in computer-aided manufacturing to control automated machine tools, as well as from a 3D-printing slicer app. It has many variants.
In machining, a metal lathe or metalworking lathe is a large class of lathes designed for precisely machining relatively hard materials. They were originally designed to machine metals; however, with the advent of plastics and other materials, and with their inherent versatility, they are used in a wide range of applications, and a broad range of materials. In machining jargon, where the larger context is already understood, they are usually simply called lathes, or else referred to by more-specific subtype names. These rigid machine tools remove material from a rotating workpiece via the movements of various cutting tools, such as tool bits and drill bits.
TRL Limited, trading as TRL is an independent private company offering a transport consultancy and research service to the public and private sector. Originally established in 1933 by the UK Government as the Road Research Laboratory (RRL), it was privatised in 1996. Its motto or tagline is 'The Future of Transport'.
The CSIR- National Physical Laboratory of India, situated in New Delhi, is the measurement standards laboratory of India. It maintains standards of SI units in India and calibrates the national standards of weights and measures.
In machining, boring is the process of enlarging a hole that has already been drilled by means of a single-point cutting tool, such as in boring a gun barrel or an engine cylinder. Boring is used to achieve greater accuracy of the diameter of a hole, and can be used to cut a tapered hole. Boring can be viewed as the internal-diameter counterpart to turning, which cuts external diameters.
The College of Technology and Engineering (CTAE), is a public engineering college located in Udaipur, Rajasthan, India. It is one of the top ranking engineering institute of the state offering varied courses in engineering.
The turret lathe is a form of metalworking lathe that is used for repetitive production of duplicate parts, which by the nature of their cutting process are usually interchangeable. It evolved from earlier lathes with the addition of the turret, which is an indexable toolholder that allows multiple cutting operations to be performed, each with a different cutting tool, in easy, rapid succession, with no need for the operator to perform set-up tasks in between or to control the toolpath. The latter is due to the toolpath's being controlled by the machine, either in jig-like fashion, via the mechanical limits placed on it by the turret's slide and stops, or via digitally-directed servomechanisms for computer numerical control lathes.
Tool and die makers are highly skilled crafters working in the manufacturing industries. Variations on the name include tool maker,toolmaker, die maker,diemaker, mold maker,moldmaker or tool jig and die-maker depending on which area of concentration or industry an individual works in.
LGC Group, formerly the Laboratory of the Government Chemist, is an international life sciences measurement and tools company. It provides the role and duties of the UK Government Chemist, a statutory role and adviser to the government. LGC also hosts the UK's National Measurement Laboratory (NML) for chemical and bio-measurement, which performs measurements for diagnostics, advanced therapeutics, safety and security, among others.
Delcam is a supplier of advanced CAD/CAM software for the manufacturing industry. The company has grown steadily since being founded formally in 1977, after initial development work at Cambridge University, UK. It is now a global developer of product design and manufacturing software, with subsidiaries and joint ventures in North America, South America, Europe and Asia with a total staff of over 800 people and local support provided from over 300 re-seller offices worldwide. It was listed on the London Stock Exchange until 6 February 2014, when it was acquired by Autodesk. It now operates as a wholly owned, independently operated subsidiary of Autodesk.
The Ministry of Chemicals and Fertilizers in India is the federal ministry with administrative purview over three departments namely:
Pratt & Whitney Measurement Systems is an American multinational corporation that specializes in producing high-precision measuring instruments and systems.
Central Institute of Tool Design or CITD is an institute in India providing programs in Tool Engineering and Technology. The CITD main campus is in Hyderabad, Telangana, with a branch campus in Vijayawada and an extension centre in Chennai.
Sir George Gray Macfarlane was a British engineer, scientific administrator and public servant.
The history of numerical control (NC) began when the automation of machine tools first incorporated concepts of abstractly programmable logic, and it continues today with the ongoing evolution of computer numerical control (CNC) technology.
