APT Programming Language
APT (Automatically Programmed Tool) is a high-level computer programming language most commonly used to generate instructions for numerically controlled machine tools. Douglas T. Ross is considered by many to be the father of APT: as head of the newly created Computer Applications Group of the Servomechanisms Laboratory at MIT in 1956, he led its technical effort. APT is a language and system that alleviates the tedious mathematics of writing toolpaths for numerically controlled equipment. This early language was used widely through the 1970s and is still a standard internationally. Derivatives of APT were later developed. Programming language APT is used to program numerically-controlled machine tools to create complex parts using a cutting tool moving in space. It is used to calculate a path that a tool must follow to generate a desired form. APT is a special-purpose language and the predecessor to modern computer aided manufacturing (CAM) systems. It was created and refined d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Numerical Control
Numerical control (also computer numerical control, and commonly called CNC) is the automated control of machining tools (such as drills, lathes, mills, grinders, routers and 3D printers) by means of a computer. A CNC machine processes a piece of material (metal, plastic, wood, ceramic, or composite) to meet specifications by following coded programmed instructions and without a manual operator directly controlling the machining operation. A CNC machine is a motorized maneuverable tool and often a motorized maneuverable platform, which are both controlled by a computer, according to specific input instructions. Instructions are delivered to a CNC machine in the form of a sequential program of machine control instructions such as G-code and M-code, and then executed. The program can be written by a person or, far more often, generated by graphical computer-aided design (CAD) or computer-aided manufacturing (CAM) software. In the case of 3D printers, the part to be printed is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RS-274
G-code (also RS-274) is the most widely used computer numerical control (CNC) programming language. It is used mainly in computer-aided manufacturing to control automated machine tools, and has many variants. G-code instructions are provided to a machine controller (industrial computer) that tells the motors where to move, how fast to move, and what path to follow. The two most common situations are that, within a machine tool such as a lathe or mill, a cutting tool is moved according to these instructions through a toolpath cutting away material to leave only the finished workpiece and/or an unfinished workpiece is precisely positioned in any of up to nine axes around the three dimensions relative to a toolpath and, either or both can move relative to each other. The same concept also extends to noncutting tools such as forming or burnishing tools, photoplotting, additive methods such as 3D printing, and measuring instruments.

STEP-NC
STEP-NC is a machine tool control language that extends the ISO 10303 STEP standards with the machining model in ISO 14649, adding geometric dimension and tolerance data for inspection, and the STEP PDM model for integration into the wider enterprise. The combined result has been standardized as ISO 10303-238 (also known as AP238). STEP-NC was designed to replace ISO 6983/RS274D G-codes with a modern, associative communications protocol that connects computer numerical controlled (CNC) process data to a product description of the part being machined. A STEP-NC program can use the full range of geometric constructs from the STEP standard to communicate device-independent toolpaths to the CNC. It can provide CAM operational descriptions and STEP CAD geometry to the CNC so workpieces, stock, fixtures and cutting tool shapes can be visualized and analyzed in the context of the toolpaths. STEP GD&T information can also be added to enable quality measurement on the control, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unigraphics
NX, formerly known as "unigraphics", is an advanced high-end CAD/CAM/ CAE, which has been owned since 2007 by Siemens Digital Industries Software. In 2000, Unigraphics purchased SDRC I-DEAS and began an effort to integrate aspects of both software packages into a single product which became Unigraphics NX or NX. It is used, among other tasks, for: * Design (parametric and direct solid/surface modelling) * Engineering analysis (static; dynamic; electro-magnetic; thermal, using the finite element method; and fluid, using the finite volume method). * Manufacturing finished design by using included machining modules. NX is a direct competitor to CATIA, Creo, Autodesk Inventor. History 1972: United Computing, Inc. releases UNIAPT, one of the world's first end-user CAM products. 1973: The company purchases the Automated Drafting and Machining (ADAM) software code from MCS in 1973.

ADAPT (programming Language)
ADAPT (formerly American Disabled for Attendant Programs Today) is a United States grassroots disability rights organization with chapters in 30 states and Washington, D.C. History The Atlantis Community was started in Denver, Colorado, in 1975, when Reverend Wade Blank, a non-disabled former nursing home recreational director, assisted several severely disabled nursing home residents to move out and start their own community. In 1978 protests were held in Denver by members of the Atlantis Community, and Blank, against the wheelchair inaccessibility of public buses in that city. These protests included the nation's first demonstration for wheelchair-accessible public buses, which was on July 5 and 6. At that protest nineteen members of the Atlantis Community (called the Gang of Nineteen) chanted "We will ride" and blocked buses with their wheelchairs, staying in the streets throughout the night. In 1983, the Gang of Nineteen started ADAPT after several years of similar local bus p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cutter Location
A cutter location (CLData) refers to the position which a CNC milling machine has been instructed to hold a milling cutter by the instructions in the program (typically G-code). Each line of motion controlling G-code consists of two parts: the type of motion from the last cutter location to the next cutter location (e.g. "G01" means linear, "G02" means circular), and the next cutter location itself (the cartesian point (20, 1.3, 4.409) in this example). "G01 X20Y1.3Z4.409" The fundamental basis for creating the cutter paths suitable for CNC milling are functions that can find valid cutter locations, and stringing them together in a series. There are two broad and conflicting approaches to the problem of generating valid cutter locations, given a CAD model and a tool definition: calculation by offsets, and calculation against triangles. Each is discussed in a later section of this article. The most common example of the general cutter location problem is cutter radius compensation ...
