A machine shop is a room, building, or company where machining, a form of subtractive manufacturing, is done. In a machine shop, machinists use machine tools and cutting tools to make parts, usually of metal or plastic (but sometimes of other materials such as glass or wood). A machine shop can be a small business (such as a job shop) or a portion of a factory, whether a toolroom or a production area for manufacturing. The building construction and the layout of the place and equipment vary, and are specific to the shop; for instance, the flooring in one shop may be concrete, or even compacted dirt, and another shop may have asphalt floors. A shop may be air-conditioned or not; but in other shops it may be necessary to maintain a controlled climate. Each shop has its own tools and machinery which differ from other shops in quantity, capability and focus of expertise.
The parts produced can be the end product of the factory, to be sold to customers in the machine industry, the car industry, the aircraft industry, or others. It may encompass the frequent machining of customized components. In other cases, companies in those fields have their own machine shops.
The production can consist of cutting, shaping, drilling, finishing, and other processes, frequently those related to metalworking. The machine tools typically include metal lathes, milling machines, machining centers, multitasking machines, drill presses, or grinding machines, many controlled with computer numerical control (CNC). Other processes, such as heat treating, electroplating, or painting of the parts before or after machining, are often done in a separate facility.
A machine shop can contain some raw materials (such as bar stock for machining) and an inventory of finished parts. These items are often stored in a warehouse. The control and traceability of the materials usually depend on the company's management and the industries that are served, standard certification of the establishment, and stewardship.
A machine shop can be a capital intensive business, because the purchase of equipment can require large investments. A machine shop can also be labour-intensive, especially if it is specialized in repairing machinery on a job production basis, but production machining (both batch production and mass production) is much more automated than it was before the development of CNC, programmable logic control (PLC), microcomputers, and robotics. It no longer requires masses of workers, although the jobs that remain tend to require high talent and skill. Training and experience in a machine shop can both be scarce and valuable.
Methodology, such as the practice of 5S, the level of compliance over safety practices and the use of personal protective equipment by the personnel, as well as the frequency of maintenance to the machines and how stringent housekeeping is performed in a shop, may vary widely from one place to another business.
History
Until the 19th century
The first machine shops started to appear in the 19th century when the Industrial Revolution was already long underway. Before the industrial revolution parts and tools were produced in workshops in local villages and cities on small-scale often for a local market. The first machinery that made possible the Industrial Revolution were also developed in similar workshops.
The production machines in the first factories were built on site, where every part was still individually made to fit. After some time those factories started their own workshops, where parts of the existing machinery were repaired or modified. In those days textiles were the dominant industry, and these industries started to further develop their own machine tools.
19th century
Further development early in the 19th century in England, Germany and Scotland of machine tools and cheaper methods for the production of steel, such as the Bessemer steel, triggered the Second Industrial Revolution, which culminated in early factory electrification, mass production and the production line. The machine shop emerged as Burghardt called, a "place in which metal parts are cut to the size required and put together to form mechanical units or machines, the machines so made to be used directly or indirectly in the production of the necessities and luxuries of civilization."
The rise of machine shops and their specific manufacturing and organizational problems triggered the early job shop management pioneers, whose theories became known as scientific management. One of the earliest publications in this field was Horace Lucian Arnold, who in 1896 wrote a first series of articles about "Modern Machine-Shop Economics." This work stretched out from production technology, production methods and factory lay out to time studies, production planning, and machine shop management. A series of publications on these topics would follow. In 1899 Joshua Rose published the book Modern machine-shop practice, about the operation, construction, and principles of shop machinery, steam engines, and electrical machinery.
20th century
In 1903 the Cyclopedia of Modern Shop Practice was published with Howard Monroe Raymond as Editor-in-Chief, and in the same year Frederick Winslow Taylor published his Shop management; a paper read before the American society of mechanical engineers. New York. Taylor had started his workmanship as a machine-shop laborer at Midvale Steel Works in 1878, and worked his way up to machine shop foreman, research director, and finally chief engineer of the works. As an independent consulting engineer one of his first major assignments was in 1898 at Bethlehem Steel was to solve an expensive machine-shop capacity problem.
In 1906 Oscar E. Perrigo published the popular book Modern machine shop, construction the equipment and management of machine shops. The first part of Modern machine shop, Perrigo (1906) focussed on the physical construction of the building and presented a model machine shop. With this model machine shop, Perrigo explored the way the space in factories could be organized.[3] This was not uncommon in his days. Many industrial engineers, like Alexander Hamilton Church, J. Slater Lewis, Hugo Diemer etc., published plans for some new industrial complex.
These works among others cumulated in the scientific management movement on which Taylor in 1911 wrote his famous The Principles of Scientific Management, a seminal text of modern organization and decision theory, with a significant part dedicated to the organization of machine shops.[4] The introduction of new cutting materials as high-speed steel, and better organization of the production by implementing new scientific management methods such as planning boards (see image), significantly improved machine shop productivity and efficiency of machine shops. In the course of the 20th century, these further increased with the further development of technology.
In the early 20th century, the power for the machine tools was still supplied by a mechanical belt, which was powered by a central steam engine. In the course of the 20th-century electric motors took over the power supply of the machine tools.
As materials and chemical substances, including cutting oil, become more sophisticated, the awareness of the impact on the environment slowly grew. In parallel to the acknowledgment of the ever-present reality of accidents and potential occupational injury, the sorting of scrap materials for recycling and the disposal of refuse evolved in an area related to the environment, safety, and health. In regulated machine shops this would turn into a constant practice supported by what would be a discipline known as EHS (for environment, health, and safety), or of a similar name, such as HQSE that would include quality assurance.
In the second part of the 20th century, automation started with numerical control (NC) automation, and computer numerical control (CNC).
Digital instruments for quality control and inspection become widely available, and the utilization of lasers for precision measurements became more common for the larger shops that can afford the equipment.
Further integration of information technology into machine tools lead to the beginning of computer-integrated manufacturing. Production design and production became integrated into CAD/CAM, and production control became integrated in enterprise resource planning.
21st century
In the late of the 20th century, the introduction of industrial robots further increased factory automation. Typical applications of robots include welding, painting, assembly, pick and place (such as packaging, palletizing and SMT), product inspection, and testing. As a result of this introduction the machine shop also "has been modernized to the extent that robotics and electronic controls have been introduced into the operation and control of machines. For small machine shops, though, having robots is more of an exception.
Machining
Machining is any of the various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. The many processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing. Exactly what the "controlled" part of the definition implies can vary, but it almost always implies the use of machine tools (in addition to just power tools and hand tools).
Though not all machine shops may have a CNC milling center, commonly, they may have access to a manual milling machine.
