Sinker EDM Of Aluminium Matrix Composites

http://www.cadfamily.com/downinfo/304425.html
Machining of composites is difficult[3?C5].Hard reinforcement induces high wear in cutting
tools.Application of wear-resistant materials such as polycrystalline diamond may be limited by
their prohibitive cost.

Parametric curve machining of a CNC milling EDM

http://www.cadfamily.com/downinfo/304424.html

When the electrode moves along the horizontal segments that are generated using computer-aided manufacturing(CAM)software,the gap controller regulates the speed of the interpolator in a CNC according to the fed back discharge voltage,as is done in the vertical direction in a
die-sinking EDM.However,many segments are required to reduce the cord error of the segmental contour.

Instructions for Using the Laser Cutter-Brief Guide to the Basics

http://www.cadfamily.com/downinfo/304421.html
At any stage the excited state atoms can release some of the energy and return to a lower-energy orbital.The energy released in the form of photons has a very specific wavelength that is dependent on the level of energy or excitation the electron when the photon is released.
Two identical atoms with electrons in identical states will release photons with identical wavelengths. This forms the basis for laser light.

Cylindrical wire EDM process-Surface Integrity and Roundness

http://www.cadfamily.com/downinfo/304416.html
Scanning Electron Microscopy SEM! has been a common tool to examine EDM surfaces @4,7#. The EDM surface consists of small craters created by electrical sparks @1#.To improve the EDM surface integrity,the size of craters needs to be small. This study uses the SEM to examine and estimate the sizes of craters.Subsurface depths of the recast layer and heat-affected zone are two
other important characteristics of the EDM surface integrity.

Modelica Assembly Construction and simulation of Modelica systems in AMESim

http://www.cadfamily.com/downinfo/304405.html

1.2. AMESim vs Modelica
Working with Modelica systems in AMESim is very similar to working with native AMESim systems.There are however several significant differences that we are going to describe below.
The most obvious difference is that in AMESim the user is responsible for fixing the causalities of component external variables,while in Modelica this is done automatically during the compilation phase.

AMESim Thermal-Hydraulic Component Design Library

http://www.cadfamily.com/downinfo/304404.html
The aim of this second tutorial example is to model very simply a high pressure fuel injector using components from the THCD library.In this special case,the level of operating pressure and the fast transient behaviour are of great importance.What we want to highlight in this example is the difference observed on the injected volume results whether the cross-coupling effects between pressure and temperature are accounted for or not.

Aspen Energy Analyzer Reference Guide

http://www.cadfamily.com/downinfo/301325.html
Targets
Targets are theoretical values that represent the ideal or perfect situation.
They are very important as an analysis tool as it provides a comparison for
how close the current design is to the optimal design.
Energy Targets
Energy targets are the minimum amount of utilities needed to satisfy the
process stream requirements (Papoulias & Grossmann, 1983). In Aspen
Energy Analyzer, the energy target values are calculated depending on the
Utility Load Allocation Method and pinch temperature. The hot and cold utility
energy targets are both displayed.
For more information on Utility Load Allocation Methods, refer to Utility Load
Allocation Methods on page 30.

Aspen Event Manager Implementation Guide

http://www.cadfamily.com/downinfo/301326.html
Overview The first step in implementing your Aspen Event Manager application is to
identify your company??s business requirements. This process involves
performing the following steps:
1 Identify the Events, Event Sources, and Entities
2 Identify the Users
3 Determine Event Outcomes
Identify the Events, Event
Sources, and Entities
Events
You must identify the business events that take place within your company or
industry that affect supply chain decisions. These events may be at a broad or
a detailed level, depending on the business scenario. For example, you can
identify an event to be ??Low Inventory?? or ??Production Line Down.??
Event Sources
Different sources can generate events, including a business process
document, an e-mail, a Web page, or a database trigger. Business rules
themselves can also generate events as the evaluation services processes
them.
As part of determining business requirements, identify which sources will be
generating events in your Aspen Event Manager application.

AZQDataService Interface
The Aspen Basic Engineering Server can load any user supplied data service
as long as the service is an ActiveX dll that supports the AZQDataService
interface. The AZQDataService interface provides methods to register
different KB routines with the server and to control execution of these KB
routines. To support the AZQDataService interface in your ActiveX object:
1. Import the Interface Definition into your project
To import the definition of AZQDataService interface into your project, use
Project/References from the Visual Basic 6 menus. On the References dialog
box, find and select ??AZDBQuery Version xx.x??, where ??xx.x?? is the current
internal version number for the Aspen Basic Engineering version
(e.g.??AZDBQuery Version 16.2?? for V7.2).

Aspen Cim-IO User's Guide

http://www.cadfamily.com/downinfo/301323.html

Cim-IO Checksum There was an incident where Cim-IO messages seemed to be corrupted. The
tag list in some of the requests were not complete, part of the tagnames were
overwritten by spaces. The problem was caused by a faulty network card.
Cim-IO uses TCP/IP because the delivery and integrity of the packets are
supposed to be guaranteed, yet the problem happened. Cim-IO analyses
messages and checks the integrity of message structures as much as possible
but it could not detect an erroneous tag since, the corruption did not affect
the structure of the message.
An enhancement was made in Cim-IO to include a checksum for each Cim-IO
message. The sender calculates a checksum on the message and includes it in
the message, the receiver extracts the checksum from the message header,
calculates its own checksum on the message it received and compare both
checksums. If the cheksums don??t match, the message is rejected and a
message is logged to the Cim-IO log file.

Flash Loader Development Guide for IAR Embedded Workbench

http://www.cadfamily.com/downinfo/304007.html
Many development boards use flash memory as the primary code memory.Normally,flash memory cannot be written directly from C-SPY when a program is to be downloaded and debugged,but must instead be flashed or programmed by a dedicated program??the flash loader??that executes on the target system.
Note:The flash loader mechanism is useful for any sort of memory that cannot be directly
written to by the debugger,but instead has to be written to by a dedicated program that executes
on the target system.Although,the flash loader is mostly used for flash memory,it can for
example also be used for various forms of external RAM or disk-like storage devices.However,
in the rest of this guide,flash memory is the assumed memory.
