Computer-aided manufacturing

In CNC manufacturing the CAM system is used to simplify the machining and design process. In most cases the CAM system will work with a CAD design made in a 3D environment. The CNC programmer will just specify the machining operations and the CAM system will create the CNC program. This compatibility of CAD/CAM systems eliminates the need for redefining the work piece configuration to the CAM system. In other words: C.A.M. is a software usually comes with a machine such as a lathe or miller which is controlled by the software. The entire system tends to be extremely expensive (a lathe a ...

In Karl Marx's labour theory of value, the concept of capital productivity is rejected as an instance of reification, and replaced with the concepts of the organic composition of capital and the value product of labor. A sharp distinction is drawn by Marx for the productivity of labor in terms of physical outputs produced, and the value or price of those outputs. A small physical output might create a large value, while a large physical output might create only a small value - with obvious consequences for the w ...

Originally, the word computing was synonymous with counting and calculating, and a science that deals with the original sense of computing mathematical calculations. "Computing" has come to mean the operation and usage of computing machines, the electrical processes carried out within the computing hardware itself, and the theoretical concepts governing them (computer science). The following definition of computing is gi ...

Some economists write of "capital productivity" (output per unit of capital goods employed), the inverse of the capital/output ratio. "Total factor productivity," sometimes called multifactor productivity, also includes both labor and capital goods in the denominator (weighted by their incomes). Unlike labor productivity, the calculation of both capital productivity and total factor productivity is dependent on a number of doubtful assumptions and is subject to the Cambridge critique. Even measures of land and labor productivity should be used only when conscious o ...

The abbreviation CNC stands for Computer(ized) Numerical(ly) Control(led), and refers specifically to the computer control of machine tools for the purpose of (repeatedly) manufacturing complex parts in metal as well as other materials, using a program written in a notation conforming to the EIA-274-D standard and commonly called G-code. CNC was developed in the late 1940s and early 1950s by the MIT Servomechanisms Laboratory. CNC machines were relatively briefly preceded by the less advanced NC, or ...

Computer-aided design (CAD) is the use of a wide range of computer-based tools that assist engineers, architects and other design professionals in their design activities. It is the main geometry authoring tool within the Product Lifecycle Management process and involves both software and sometimes special-purpose hardware. Current packages range from 2D vector based drafting systems to 3D parametric surface and solid design modellers. CAD is sometimes translated as "computer-assisted", "computer-aided drafting", or a si ...

Companies can increase productivity in a variety of ways. The most obvious methods involve automation and computerization which minimize the tasks that must be performed by employees. Recently, less obvious techniques are being employed that involve ergonomic design and worker comfort. A comfortable employee, the theory maintains, can produce more than a counterpart who struggles through the day. In fact, some studies claim that measures such as raising workplace temperature can have a drastic effect on office productivity. Experiments done ...

Productivity studies analyze technical processes and engineering relationships such as how much of an output can be produced in a specified period of time (see also Taylorism). It is related to the concept of efficiency, which is the amount of output produced relative to the amount of resources (time and money) that go into the production. All else constant, it benefits a business to improve productivity, which over time lowers cost and (hopefully) improves ability to compete and make profit. Increases in productivity also influence society more broadly, by improving liv ...

Labor productivity is generally speaking held to be the same as the "average product of labor" (average output per worker or per worker-hour, an output which could be measured in physical terms or in price terms). It is not the same as the marginal product of labor, which refers to the increase in output that results from a corresponding increase in labor input. However, some aspects of labor productivity may be very difficult to measure exactly, or in an unbiased way, such as: the intensity of labor- ...

Many software solutions have been developed to organize and integrate the different phases of a product’s lifecycle. PLM should not be seen as a single software product but a collection of software tools and working methods integrated together to address either single stages of the lifecycle or connect different tasks or manage the whole process. Some software providers cover the whole PLM range while others a single niche application. Some applications can span many fields of PLM with different modules within the same data model. An overv ...

CAE tools are very widely used in auto industry. In fact, their use has enabled the automakers to reduce product development cost and time while improving safety, comfort, and durability of the vehicles they produce. The predictive capability of CAE tools has progressed to the point where much of the design verification is now done using computer simulations rather than physical prototype testing. Software such as LSTC’s LSDYNA and ESI’s PAM Crash are used for Automotive crashworthiness and Occupant safety. Other tools like MSC’s Patran and ADAMS software, and UGS’s Scenario and Nastran packa ...

The introduction of CNC machines radically changed the manufacturing industry. Curves are as easy to cut as straight lines, complex 3-D structures are relatively easy to produce, and the number of machining steps that required human action have been dramatically reduced. With the increased automation of manufacturing processes with CNC machining, considerable improvements in consistency and quality have been achieved. CNC automation reduced the frequency of errors and provided CNC operators with time to perform additional tasks. CNC a ...

Computer-aided design - Architecture. The software package may produce its results in several formats, but typically provides a graphically-based result which is then able to be used to create concept sketches for assessment and approval, and eventually working drawings. An example would be a structural design package used to assess the integrity of a steel-framed building by performing all the calculations necessary to determine the size and strength of the components, and the effect of such things as wind-loadi ...

The machine has been greatly modified for various applications however a familiarity with the basics shows the similarities between types. These machines consist of, at the least, a headstock, bed, carriage and tailstock. The better machines are solidly constructed with broad bearing surfaces (slides or ways) for stability and manufactured with great precision. This helps ensure the components manufactured on the machines can meet the required tolerances and repeatability required. See also:

This is an ever changing industry with many well know products and companies being taken over and merged with others. There are many CAD software products currently on the market. More than half of the market is however covered by the four main PLM corporations Autodesk, Dassault Systemes, PTC, and UGS Corp., but there are many other CAD packages with smaller user bases or covering niche user areas. Packages can be classified into 3 types: 2D drafting systems (e.g. AutoCAD, Microstation); mid-range 3D solid feature modellers (e.g. Sol ...
