Heat Assisted Machining of Hardened Steel AISI H13
ISBN: 9783845422046 / Angielski / Miękka / 2012 / 172 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Hardened steels, like AISI H13 and D2 extensively as the hot working tools, dies and moulds due to their high hardness and heat resistant properties. However the same properties are responsible for poor machinabilty of these materials. The challenges in machining of these materials in hardened state called for many research works. This book introduces induction heating as a new online heating technique to improve machinability hardened steel AISI H13. The research work considered the influence of heating parameter - temperature; and cutting parameters - cutting speed, feed and axial depth of...

The Informal Sector in Asia
ISBN: 9783639241563 / Angielski / Miękka / 2010 / 144 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Many contemporary societies are in turmoil for widespread poverty, joblessness, socio-economic polarization and environmental degradation. Every government now utilizes the free market system and profit motive for economic growth and development. No government however is seriously engaged in reducing inequalities, creating employment, provisioning basic services and reversing environmental degradation. As a result, most people, particularly the children, the women and the old work and live precariously. It is in this distressing background that this book analyses the informal sector growth...

High Speed Machining of Titanium Alloy, Ti6al4v
ISBN: 9783659219597 / Angielski / Miękka / 2012 / 128 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. High speed end milling of Titanium alloy Ti6Al4V is a potential machining technique for obtaining nano level surface finish using small diameter (2mm and 4mm) tools applying high rpm to facilitate the application of of low values (micro-meter level) of feeda and depth of cut to ensure super finishing that could avoid the need of further grinding and polishing operations. Influences of three cutting parameters, namely cutting speed, axial depth of cut and feed, were analyzed. Mathematical models were developed for output responses Ra and Rt. Analysis of multiple response optimizations of RSM...

Improved Machinability of Titanium Alloy Ti-6Al-4V
ISBN: 9783838373072 / Angielski / Miękka / 2011 / 172 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Titanium alloys are generally regarded as difficult- to-cut materials and plentiful research works have been conducted on their machinability in the past few decades with several diverse objectives, such as improvement on tool life, surface finish and surface integrity, investigation on chip and tool wear morphology, cutting force and vibration/chatter. This study introduces induction preheating as one of the new variable parameters to improve the machinability of titanium Ti-6Al-4V alloy. In the current work the influence of heating parameter i.e. preheating temperature, and the...

Induction Heat Assisted End Milling of Inconel 718 and Ti6al4v Alloys
ISBN: 9783659439933 / Angielski / Miękka / 2013 / 196 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Inconel 718 is the most widely used in the aerospace industries, especially for gas turbine hot section components. Titanium alloys, on the other hand, have very high strength-to-weight ratio making them very suitable for aircraft engines and airframe manufacture. They account for 30% of the total engine mass in commercial and 40% in military projects. However, both these strategic materials have poor machinability, as a result of which they have dominated the major research interests in metal cutting industries in the past decades. One of the techniques to improve machinability is the use an...

Chatter Control in Induction Heat Assisted End Milling
ISBN: 9783659436543 / Angielski / Miękka / 2013 / 132 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The conventional induction heating method, used for heat treatment of parts has been customized as a novel method for heat assisted machining of metallic materials. This method is very clean and of low cost compared to laser heating. The method is especially applicable in milling operations with high width of cut, which a single laser can not cover and there is a need of employing multiple lasers. Heating time is very short and only the skin of the work piece is heated and removed during machining. Cutting forces are low due to lower yield strength of the materials at elevated temperature,...
