Abstract
One of the biggest problems of artisans , is notching the high speed steel roller is due to the inability to do this work, become high speed steel roller bearings are disposable. One of the biggest problems of artisans , is notching the high speed steel roller is due to the inability to do this work, become high speed steel roller bearings are disposable.When the roller is placed on the production line, because of the retained austenite make it very hard. High speed roller used in this study is barely above 70 Shc. Our goal is to obtain the optimum machining parameters that it requires a high number of tests that are practically impossible. So in order to achieve optimal machining parameters with the lowest test, RSM method in Minitab software was used. CBN tools performed well in all tests and succeeded with the best cutting speed 25 m/min, 0.05 mm feed and 0.05 mm depth of cut at the time of 1080 seconds, in notching one caliber.

Abstract [Persian]
یکی از مشکلات عظیم صنعتگران در زمینه غلتک‌های میلگرد از جنس فولاد تندبر، آج-زدن این غلتک‌ها است که به‌علت عدم توانایی لازم در این کار، غلتک‌های تندبر تبدیل به غلتک‌های یکبار مصرف شده‌اند. یکی از مشکلات عظیم صنعتگران در زمینه غلتک‌های میلگرد از جنس فولاد تندبر، آج-زدن این غلتک‌ها است که به‌علت عدم توانایی لازم در این کار، غلتک‌های تندبر تبدیل به غلتک‌های یکبار مصرف شده‌اند.هنگامی که بر روی این غلتک‌ها نورد انجام می‌شود، به دلیل آستنیت باقیمانده، کار سختی بالایی پیدا می‌کند و آج‌زنی بسیار مشکل می‌شود. در این تحقیق غلتک‌های تندبر با سختی بالای 70 شورسی مورد بررسی قرار گرفتند. هدف ما به‌دست آوردن پارامترهای بهینه ماشینکاری است که به منظور دستیابی به این هدف با انجام کمترین آزمایش، روش RSM در نرم افزار مینی‌تب مورد استفاده قرار گرفت. ابزار CBN در همه تست‌ها عملکرد خوبی داشته و در بهترین حالت با سرعت برشی m/min 25، پیشروی mm/rev 05/0 و عمق بار mm 05/ 0در زمان 1080 ثانیه یک کالیبر آج‌زده شد.
