چکیده

سیم‌­های به‌کار رفته در فرآیند وایرکات به‌عنوان عامل برش قطعه کار از اهمیت بالایی در این روش ماشین‌کاری نوین برخوردارند. عواملی مانند قطر سیم­‌ها، جنس آن‌­ها و روش ساختشان باعث می­‌شود تا تولید آن­ها به‌سادگی امکان‌پذیر نباشد. در پژوهش پیش رو یک نوع سیم پرکاربرد در صنعت داخل کشور انتخاب (تولید شده در کشور چین) ، بررسی و آنالیز شده است. در مراحل اولیه پژوهش نمونه سیم چینی آنالیز عنصری شد و ترکیبات آن استخراج شد، سپس تحت آزمون کشش قرار گرفت و خواص مکانیکی آن نیز به دست آمد. در مراحل بعدی سیم باهدف بومی‌سازی فرایند ساخت آن توسط دو روش ریخته­‌گری و اکستروژن ساخته شد و مجددا تحت آنالیزهای شیمیایی و آزمون کشش قرار گرفت. همچنین در مرحله نهایی تمامی سیم‌­های ساخته‌شده بر روی دستگاه وایرکات تحت پارامترها و شرایط یکسان قرار داده و بر روی یک قطعه کار آزمایش شدند. نوآوری مهم پژوهش کنونی درروش ساخت سیم وایرکات به روش اکستروژن به‌منظور تولید انبوه در داخل کشور می­‌باشد. نمونه سیم ساخته شده، تا 80% استحکام بیشتری نسبت به سیم چینی داشته و همچنین 10 برابر نرم­‌تر از آن است که این افزایش استحکام و نرمی بیشتر منجر به مقاومت بیشتر سیم و کاهش احتمال پارگی آن حین عملیات ماشینکاری می‌­شود.

چکیده [English]

The wires used in the wire EDM process are of great importance in this new machining process as the cutting agent of the workpiece. Factors such as the diameter of these wires, their material, and their manufacturing method make their production simply not possible. In the upcoming research, a widely used type of Chinese wire in the domestic industry has been selected, examined, and analyzed. In the early stages of the research, the Chinese wire sample was elementally analyzed and its compounds were extracted, then it was subjected to a tensile test and its mechanical properties were also extracted. In the next steps, the wire was made with the aim of making a Chinese model by two methods of casting and extrusion and was again subjected to chemical analysis and tensile test. Also, in the final stage, all the wires made on the wire EDM machine were put under the same parameters and conditions and tested on a piece of work. The important innovation of the current research is in making wire EDM wire by extrusion method for mass production inside the country. The manufactured wire sample has up to 80% more strength than Chinese wire and is also 10 times softer than that, which increases the strength and softness of the wire leading to greater resistance of the wire and reducing the possibility of its tearing during machining operations.
