Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), [1] is a category of software tools for designing electronic systems such as integrated circuits and printed circuit boards.
The world of electronic design automation (EDA) software for integrated circuit (IC) design is dominated by the three vendors Synopsys, Cadence Design Systems and Siemens EDA (Formerly Mentor Graphics, acquired in 2017 by Siemens) which have a revenue respectively of 4,2 billion US$, 3 billion US$ and 1,3 billion US$.
CP (North America) Inc., [1] doing business as Chassis Plans, is an American military and industrial computer systems manufacturer specializing in rackmount computers, military computers, rugged computers, industrial PCs, rackmount LCDs, single-board computer systems with passive and active backplanes and motherboard systems.
Cutting-stock problems can be classified in several ways. [1] One way is the dimensionality of the cutting: the above example illustrates a one-dimensional (1D) problem; other industrial applications of 1D occur when cutting pipes, cables, and steel bars. Two-dimensional (2D) problems are encountered in furniture, clothing and glass production.
Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. [ 1 ] : 3 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.
The upper and lower diamond guides are usually accurate to 0.004 mm (0.16 mils), and can have a cutting path or kerf as small as 0.021 mm (0.83 mils) using Ø 0.02 mm (0.79 mils) wire, though the average cutting kerf that achieves the best economic cost and machining time is 0.335 mm (13.2 mils) using Ø 0.25 mm (9.8 mils) brass wire.
EBM can be used for very precise cutting or boring of a wide variety of metals. Surface finish is better and kerf width is narrower than those for other thermal cutting processes. EBM process is best suitable for high melting point and high thermal conductivity materials. The EBM beam is operated in pulse mode.
Guillotine cutting is the process of producing small rectangular items of fixed dimensions from a given large rectangular sheet, using only guillotine-cuts. A guillotine-cut (also called an edge-to-edge cut) is a straight bisecting line going from one edge of an existing rectangle to the opposite edge, similarly to a paper guillotine.
