on the practicality and effectiveness of a personalized eclectic method incorporated into iranian high school efl syllabus

همگام با سرعت در حال رشد خلاقیت و نوآوری های آموزش زبان به ویژه ظهور روش ارتباطی آموزش زبان? بسیاری از مدارس زبان با بازاندیشی آموزش و پرورش خود? برای گنجاندن فعالیت های ارتباطی، وزمینه ی شخصی سازی شده به شیوه های سنتی خود به روز رسانی شده اند. با این حال، مدارس ایرانی در این زمینه آهسته پیش رفته اند. از این رو، هدف عمده ی پژوهش حاضر برداشتن یک گام در پر کردن شکاف بین نظریه های آموزشی نو ظهور و...

Influence of the Tool Edge Geometry on Specific Cutting Energy at High- Speed Cutting

This paper presents specific cutting energy measurements as a function of the cutting speed and tool cutting edge geometry. The experimental work was carried out on a vertical CNC machining center with 7,500 rpm spindle rotation and 7.5 kW power. Hardened steels ASTM H13 (50 HRC) were machined at conventional cutting speed and high-speed cutting (HSC). TiN coated carbides with seven different g...

The Effect of Power and Maximum Cutting Speed on the Material Removal Rate and Cutting Volume Efficiency in CO2 Laser Cutting of Polycarbonate Sheets

In the laser cutting process some well-known parameters, e.g. laser power and cutting speed, play major roles in the performance of the process. Each parameter or a combination of parameters can affect the material removal volume and cutting volume efficiency. The purpose of this research is to study the effect of power and maximum cutting speed on the material removal rate (MRR) and cutting vo...
