Drilling Process of Composite Laminates – a Tool Based Analysis
The distinctive characteristics of carbon fibre reinforced plastics, like low weight or high specific strength, had broadened their use to new fields. In order to join different components by using bolts, rivets or screws, one of the machining operations needed in composite structures is drilling. Usually, it is accepted that drilling can be carried out using conventional tools and machinery wi...
متن کاملModelling of Tool Life, Torque and Thrust Force in Drilling: a Neuro-fuzzy Approach
This paper presents the application of neuro-fuzzy approach for modelling tool life, torque and thrust force in drilling operation for set of given process parameters, namely cutting speed, feed rate and drill diameter. The proposed approach uses a hybrid-learning algorithm i.e., combination of the back-propagation gradient descent method and least squares method, to identify premise and conseq...
متن کاملvibration drilling tool and thrust force investigation in vibratory drilling process of al 2024-t6
vibratory drilling (vd)process is a new modern technology where longitudinal wave with high frequency (more than 16 khz) and low amplitude (usually between 2 up to 30 µm) is superimposed on the movement of cutting tool, resulting in connection and disconnection of cutting tool engagement with workpiece. in this study, in order to perform vibratory drilling process, two vibration tools are desig...

بررسی و مقایسه تفاوتها و شباهت های ترجمه ی درون زبانی و برون زبانی با تمرکز بر زبانشناسی متن. برای امر مقایسه میزان بسامد تصریح به کار رفته در ترجمه ی درون زبانی و نیز برون زبانی شاهنامه ی فردوسی مورد بررسی قرار گرفت.
a frame semantic approach to the study of translating cultural scripts in salingers franny and zooey
the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...
