INTRODUCTION Optimization of machining parameters is essential for improving expected outcome of any machining operation. CASE DESCRIPTION The aim of this work is to find out optimum values of machining parameters to achieve minimal surface roughness during milling operation of GFRP. DISCUSSION AND EVALUATION In this machining operation speed, depth of cut and feed rate are considered as pa...
During the past decades, FRP strengthened RC structures have attracted worldwide interest in both application and research. Nowadays, as more and more infrastructures are being suffered from severe corrosions due to harsh and extreme environments, the durability of FRP strengthened RC structures has generally emerged as the most important issue in research. Thus, the paper presents the latest p...
Glass fiber reinforced plastic (GFRP) composite materials are a feasible alternative to engineering materials and are being extensively used in variety of engineering applications. Accordingly, the need for accurate machining of composites has increased enormously. During machining, the obtained surface roughness is an important aspect. The present investigation deals with the study and develop...
Drilling is an hole making process in metal cutting operation performed by extrusion which finds wide application in various industries for manufacturing components using metals and non metals. This process is applied widely in assembly of components or elements, where processing challenges are severe issue such as to maintain surface integrity, ovality, machining time, Metal Removal Rate etc.,...
در روسازیهای بتنی، به منظور انتقال بار و جلوگیری از پلکانی شدن درز، به میله داول نیاز است. معمولترین داولهای مورد استفاده برای این منظور، داول فولادی بـا پوشش اپوکسی با قطر بین 25 تا 38 میلیمتر به منظور دوام در برابر خوردگی است. لیکن خوردگی این نوع داول در طول عمر روسازی، باعث شکست بتن در اطراف داول و در نتیجه شل شدن داول خواهد شد. در این مقاله استفاده از میله های پلیمری (gfrp)1 به عنوان ابزار ...
