Cutting Tool Technology: Industrial Handbook
By Graham T. Smith


Publisher: Springer
Number Of Pages: 600
Publication Date: 2008-07-28
ISBN-10 / ASIN: 1848002041
ISBN-13 / EAN: 9781848002043
Binding: Hardcover
Product Description:


It is a well acknowledged fact that virtually all of our modern-day components and assemblies rely to some extent on machining operations in their manufacturing process. Thus, there is clearly a substantive machining requirement which will continue to be of prime importance for the foreseeable future. Cutting Tool Technology provides a comprehensive guide to the latest developments in the use of cutting tool technology. The book covers new machining and tooling topics such as high-speed and hard-part machining, near-dry and dry-machining strategies, multi-functional tooling, ‘diamond-like’ and ‘atomically-modified’ coatings, plus many others. Also covered are subjects important from a research perspective, such as micro-machining and artificial intelligence coupled to neural network tool condition monitoring. A practical handbook complete with troubleshooting tables for common problems, Cutting Tool Technology is an invaluable reference for researchers, manufacturers and users of cutting tools.

:Product Description


This book gives an unparalleled, up-to-date, in-depth treatment of all kinds of flow phenomena encountered in centrifugal pumps including the complex interactions of fluid flow with vibrations and wear of materials.

The scope includes: all aspects of hydraulic design, 3D-flow phenomena and partload operation, cavitation, numerical flow calculations, hydraulic forces, pressure pulsations, noise, pump vibrations (notably bearing housing vibration diagnostics and remedies), pipe vibrations, pump characteristics and pump operation, the effects of highly viscous flows, pumping of gas-liquid mixtures, hydraulic transport of solids, fatigue damage to impellers or diffusers, material selection under the aspects of fatigue, corrosion, erosion-corrosion or hydro-abrasive wear, pump selection, and hydraulic quality criteria.

To ease the use of the information, the methods and procedures for the various calculations and failure diagnostics discussed in the text are gathered in more than 100 pages of tables which may be considered almost unique in the open literature. The text focuses on practical application in the industry and is free of mathematical or theoretical ballast. In order to find viable solutions in practice, the physical mechanisms involved should be thoroughly understood. The book is focused on fostering this understanding which will benefit the pump engineer in industry as well as academia and students.

Elite Software Chvac ver. 7.01.41 | Win32 | Size: 16,65 Mb

Chvac quickly and accurately calculates the maximum heating and cooling loads for commercial buildings. The cooling loads can be calculated with either the CLTD method or the new RTS (Radiant Time Series) method. The program allows an unlimited number of zones which can be grouped into as many as 100 air handling systems. Chvac automatically looks up all cooling load and correction factors necessary for computing loads. In addition, it can look up outdoor design weather data for over 2000 cities located around the world. There is also provision for editing the weather data as well as adding data for other cities. Comprehensive reports list the general project data, detailed zone loads, air handler summary loads, outside air loads, total building loads, building envelope analysis, tonnage requirements, CFM air quantities, chilled water flow rates (if applicable), and complete psychrometric data with entering and leaving coil conditions. Other outstanding features include ASHRAE Standard 62 analysis, automatic building rotation, 360 degree wall orientations, tilted glass, exterior shading, internal operating load profiles, variable indoor design temperatures, people diversity, pretreated outside air, seasonal infiltration and ventilation rates, reheat loads, duct gains and losses, and return air plenums.

Features:
* Calculates Peak Heating & Cooling Loads
* Determines Building Tonnage and Room CFM Requirements, and Runout Duct Sizes
* Uses either the RTS or CLTD calculation method
* Computes CFM Air Quantities With Psychrometrics
* Calculates from Manually Entered Data or Directly from Floor Plans Created with Drawing Board (sold separately)
* Links with Elite Software's Energy Audit and EZDOE Energy Programs
* Transfers data to the eQUEST and PowerDOE Energy Analysis Programs
* Allows 30 Walls, 30 Windows, and 12 Roofs per Zone
* Automates Compliance with ASHRAE Standard 62
* Calculates in both Metric and English Units
* Converts any project from English to Metric units and vice-versa

Elite RHVAC v8.01.217 With Manual D



Elite RHVAC v8.01.217 With Manual D Ductsize
24.01mb | Windows | RS.com

A requirement for any architect, HVAC Engineer, Home Performance Contractor, or Building Scientist. Rhvac makes heating and cooling load calculation and duct sizing as easy as they can be - with one-click help on virtually every input, favorite material lists, automatic error checking and more. Try it today and see if it isn't the most user-friendly and powerful load calculation and duct sizing program you can get.

This is one of two programs approved by ASHRAE to perform manual J load calculations. It is easy to use and comes with everything you need including a drawing board. The only drawback is that it does not include an unlocker for the Manual D Ductsize portion of this program. Please note that Elite's Ductsize 6 is only for commercial buildings. Therefore, the Manual D Ductsize portion is a necessity. If you have a keygen or crack for the Manual D Ductsize portion, please post it and save some starving students!

predicitive maintenance of pumps using condition monitoring

Book Description:

This book shows how condition monitoring can be applied to detect internal degradation in pumps so that appropriate maintenance can be decided upon based on actual condition rather than arbitrary time scales.
The book focuses on the main condition monitoring techniques particularly relevant to pumps (vibration analysis, performance analysis). The philosophy of condition monitoring is briefly summarised and field examples show how condition monitoring is applied to detect internal degration in pumps.

* The first book devoted to condition monitoring and predictive maintenance in pumps.
* Explains how to minimise energy costs, limit overhauls and reduce maintenance expenditure.
* Includes material not found anywhere else.

Axial Flux Permanent Magnet Brushless Machines
By Jacek F. Gieras, Rong-Jie Wang, Maarten J. Kamper

Publisher: Springer
Number Of Pages: 364
Publication Date: 2008-06-06
ISBN-10 / ASIN: 1402069936
ISBN-13 / EAN: 9781402069932
Binding: Hardcover
Product Description:

Axial Flux Permanent Magnet (AFPM) brushless machines are modern electrical machines with a lot of advantages over their conventional counterparts. They are being increasingly used in consumer electronics, public life, instrumentation and automation system, clinical engineering, industrial electromechanical drives, automobile manufacturing industry, electric and hybrid electric vehicles, marine vessels and toys. They are also used in more electric aircrafts and many other applications on larger scale. New applications have also emerged in distributed generation systems (wind turbine generators, high-speed micro turbine generators), miniature power supplies, flywheel energy storages, aircraft and rotorcraft actuators, missile fin actuators, naval integrated motor-propellers (rim driven thrusters). The role of axial flux PM brushless machines is increasing especially in applications where integration of motors with other mechanical parts is imperative.

This book deals with the analysis, construction, design, control and applications of AFPM machines. The authors present their own research results, as well as significant research contributions made by others.

Growing interest in new topologies of permanent magnet (PM) brushless machines has prompted the authors to update the first edition of Axial Flux Permanent Magnet Brushless Machines. In this second edition new sections (non-overlap concentrated coil windings, rotor dynamics, miniature axial flux PM motors, in-wheel motors), new examples of applications and more numerical examples have been added. On request of engineers involved in axial flux PM motors technology, a CD with all numerical examples solved in Mathcad has been attached.

This monograph will be of interest to electrical engineers and other engineers involved in the design and application of AFPM brushless machine drives. It will be an important resource for researchers and graduate students in the field of electrical machine and drives
