First Article Inspection
A First Article Inspection (FAI) is a design verification process for verifying that a new or modified production process produces conforming parts that meet the manufacturing specification detailed in technical or engineering drawings. Typically, a supplier performs the FAI and the purchaser reviews the report. The FAI process usually consists of fully testing and inspecting either the first part produced by the new process or a sample from the first batch of parts. First article inspection is typically a purchase order requirement of the purchaser for the supplier to complete. If the manufacturer doesn't have the in-house capability or if the purchaser requests, the first article inspection may be conducted by an approved subcontract supplier such as a dimensional inspection/metrology laboratory. Dimensional characteristics (size, shape, and feature location) are normally inspected using calibrated tools such as Coordinate Measuring Machines (CMMs), Vernier calipers, Go/no go ...

Purchase Order
A purchase order is a commercial document and first official offer issued by a buyer to a seller, indicating types, quantities, and agreed prices for products or services. It is used to control the purchasing of products and services from external suppliers. Purchase orders can be an essential part of enterprise resource planning system orders. An indent is a purchase order often placed through an agent (indent agent) under specified conditions of sale. The issue of a purchase order does not itself form a contract. If no prior contract exists, then it is the acceptance of the order by the seller that forms a contract between the buyer and seller. Overview Purchase orders allow buyers to clearly and openly communicate with the sellers to maintain transparency. They may also help a purchasing agent to manage incoming orders and pending orders. Sellers are also protected by the use of purchase orders, in case of a buyer's refusal to pay for goods or services. Purchase orders ...

The Wichita division was responsible for construction of many important aircraft in Boeing's history, includi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombardier Aerospace
Bombardier Aviation is a division of Bombardier Inc. It is headquartered in Dorval, Quebec, Canada. Its most popular aircraft included the Dash 8 Series 400, CRJ100/200/440, and CRJ700/900/1000 lines of regional airliners, and the newer CSeries. It also manufactured the Bombardier 415 amphibious water-bomber (in Dorval and North Bay), and currently makes the Global Express and the Challenger lines of business jets. At one time, Bombardier had manufacturing plants in 27 countries, employing over 70,000 workers, but has since trimmed its workforce to less than half and reduced its holdings. History Early activities After acquiring Canadair in 1986 and restoring it to profitability, in 1989 Bombardier acquired the near-bankrupt Short Brothers aircraft manufacturing company in Belfast, Northern Ireland. This was followed in 1990 by the acquisition of the bankrupt American company Learjet, a manufacturer of business jets headquartered in Wichita, Kansas; and finally t ...

Triangulation
In trigonometry and geometry, triangulation is the process of determining the location of a point by forming triangles to the point from known points. Applications In surveying Specifically in surveying, triangulation involves only angle measurements at known points, rather than measuring distances to the point directly as in trilateration; the use of both angles and distance measurements is referred to as triangulateration. In computer vision Computer stereo vision and optical 3D measuring systems use this principle to determine the spatial dimensions and the geometry of an item. Basically, the configuration consists of two sensors observing the item. One of the sensors is typically a digital camera device, and the other one can also be a camera or a light projector. The projection centers of the sensors and the considered point on the object's surface define a (spatial) triangle. Within this triangle, the distance between the sensors is the base ''b'' and must be known. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coordinate Vector
In linear algebra, a coordinate vector is a representation of a vector as an ordered list of numbers (a tuple) that describes the vector in terms of a particular ordered basis. An easy example may be a position such as (5, 2, 1) in a 3-dimensional Cartesian coordinate system with the basis as the axes of this system. Coordinates are always specified relative to an ordered basis. Bases and their associated coordinate representations let one realize vector spaces and linear transformations concretely as column vectors, row vectors, and matrices; hence, they are useful in calculations. The idea of a coordinate vector can also be used for infinite-dimensional vector spaces, as addressed below. Definition Let ''V'' be a vector space of dimension ''n'' over a field ''F'' and let : B = \ be an ordered basis for ''V''. Then for every v \in V there is a unique linear combination of the basis vectors that equals '' v '': : v = \alpha _1 b_1 + \alpha _2 b_2 + \cdots + \alpha _n b_n . ...

Quality Management System
A quality management system (QMS) is a collection of business processes focused on consistently meeting customer requirements and enhancing their satisfaction. It is aligned with an organization's purpose and strategic direction (ISO 9001:2015). It is expressed as the organizational goals and aspirations, policies, processes, documented information, and resources needed to implement and maintain it. Early quality management systems emphasized predictable outcomes of an industrial product production line, using simple statistics and random sampling. By the 20th century, labor inputs were typically the most costly inputs in most industrialized societies, so focus shifted to team cooperation and dynamics, especially the early signaling of problems via a continual improvement cycle. In the 21st century, QMS has tended to converge with sustainability and transparency initiatives, as both investor and customer satisfaction and perceived quality are increasingly tied to these factors. ...

International Laboratory Accreditation Cooperation
The International Laboratory Accreditation Cooperation or ILAC started as a conference in 1977 with the aim of developing international cooperation for facilitating trade by promotion of the acceptance of accredited test and calibration results. In 1996, ILAC became a formal cooperation with a charter to establish a network of mutual recognition agreements among accreditation bodies that would fulfil this aim. The ultimate aim of the ILAC is increased use and acceptance by industry as well as government of the results from accredited laboratories, including results from laboratories in other countries. In this way, the free-trade goal of a 'product tested once and accepted everywhere' can be realised.

Dimensional Metrology
Dimensional metrology is the science of using physical measurement equipment to quantify the physical size, form, characteristics, and relational distance from any given feature. History of metrology Standardized measurements are essential to technological advancement, and early measurement tools have been found dating back to the dawn of human civilization. Early Mesopotamian and Egyptian metrologists created a set of measurement standards based on body parts known as anthropic units. These ancient systems of measurements utilized fingers, palms, hands, feet, and paces as intervals. Carpenters and surveyors were some of the first dimensional inspectors, and many specialized units craftsmen, such as the remen, were worked into a system of unit fractions that allowed for calculations utilizing analytic geometry. Later agricultural measures such as feet, yards, paces, Cubits, fathoms, rods, cords, perch, stadia, miles and degrees of the Earth's circumference, many of which are ...

Medical Device
A medical device is any device intended to be used for medical purposes. Significant potential for hazards are inherent when using a device for medical purposes and thus medical devices must be proved safe and effective with reasonable assurance before regulating governments allow marketing of the device in their country. As a general rule, as the associated risk of the device increases the amount of testing required to establish safety and efficacy also increases. Further, as associated risk increases the potential benefit to the patient must also increase. Discovery of what would be considered a medical device by modern standards dates as far back as c. 7000 BC in Baluchistan where Neolithic dentists used flint-tipped drills and bowstrings. Study of archeology and Roman medical literature also indicate that many types of medical devices were in widespread use during the time of ancient Rome. In the United States it wasn't until the Federal Food, Drug, and Cosmetic Act (F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
