[ 2 ] - Investigation of Cutting Forces Superalloy Inconel 718
Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...
[ 3 ] - آجزنی غلتکهای فولاد تندبر با سختی بالا جهت نورد گرم میلگرد
یکی از مشکلات عظیم صنعتگران در زمینه غلتکهای میلگرد از جنس فولاد تندبر، آجزدن این غلتکها است که بهعلت عدم توانایی لازم در این کار، غلتکهای تندبر تبدیل بهغلتکهای یکبار مصرف شدهاند. هنگامی که بر روی این غلتکها نورد انجام میشود، بهدلیل آستنیت باقیمانده، کار سختی بالایی پیدا میکند و آجزنی بسیار مشکل می-شود. در این تحقیق غلتکهای تندبر با سختی بالای 70 شورسی مورد بررسی قرار گرفتند. برای...
