After failing twice, finally I got an offer to work in Japan. Thank you to FAST OFFER International for giving me this golden opportunity. Before this, I got a scholarship to study in Japan and during the preparation program, I failed the exam in the very last semester. Next, after I finished my precision mechanical degree, I got offered to work in Japan through my University. However, due to COVID-19, I need to wait for a long period to go to Japan and eventually the company suffers a huge deficit. Since I cannot go to Japan twice, I felt hopeless and demoralized.
But, thanks to my friend too who suggested I use the fast offer. He encouraged me to apply as he knows how much I longing and love Japan. Yes, I very love Japan in the aspect of its traditional culture, technology, and philosophy. During my 2 month and a half internship in Osaka, I indulged in the beauty of Japan. I joined Bon Odori, and Hanabi Taikai, visit numerous museums and also learned the way of Japanese thinking during internship. These experiences make me way more eager to work in Japan someday.
To be honest, the FAST OFFER International staff and sensei supported me a lot. No words can describe how much I want to thank them. I applied to FAST OFFER International during my working time as a production engineer. It is very tiring to work in the morning until night as I need to do overtime and at the same time, do the assessment for an interview during the middle of the night. Even though I am busy working, the staff and sensei understand me. They helped me to re-organize and re-schedule to fit my suitable time.
As long you follow the instruction such as providing a 1-minute video, a summary of your research, why you want to work in Japan, a presentation slide, and so on. It should be fine. What the most important is PRACTICE! Later, the sensei will consult you. They also will point out which part you can improve. Me, as I did not know the technical terms in Japanese, the sensei helped me a lot. They helped me to find the suitable word and make the sentence easy to comprehend. FAST OFFER International also provides a Japanese class for an interview, which helps as you can also know how other candidates portrayed themselves during the interview. During the class, you can compare yourself with other candidates and improve the way you present later during the interview.
From FAST OFFER International, I got 4 job interviews and passed 1. At some stage, I failed the SPI test or technical interview. Please do a lot of practice with the SPI test to enhance your solving skill with limited time. As I applied for the fast offer during working, I did not have much time to practice and I learned the hard way by failing the first three interviews. Please also research the company you offered and give the very best during the interview. Of course, you can practice with the sensei first before the real interview.
Last but not least, thank you again Fast offer for providing this platform for all of us to work in Japan. They not only provide, but they also guide you on how to excel in interviews. All of the processes are tiring and it is okay to feel demoralized but do not let that emotion take you anywhere. Take some time to heal, step back for self-reflection and leap forward higher just like the slingshot.
精密ボールねじは、回転運動を摩擦の少ない直線運動に変換する機械式アクチュエータです。摩擦の少ない直線運動に変換する機械的なアクチュエータです。この精密ボールねじは、精密位置決め産業における高精度な要求を満たすために、ラッピング加工が必要です。これまで、このラッピング加工は熟練工の手作業で行われており、非常に手間のかかる作業でした。しかし、高精度なボールねじ軸の需要は増加しているが、ボールねじの製造工程はまだ改善されていないため、ボールねじの生産は停滞しています。
そこで本プロジェクトでは、既存の自動ラップ盤に超音波加工技術を付加し、ボールネジの生産性向上と表面粗さの向上を図るとともに、従来の人力による加工から脱却することを目的としたものであります。その結果、超音波を利用した新しいツールホルダの設計し、シミュレーションし、製作を行います。設計する際に、19個のデザインがあります。
また、工具ホルダーの変形と振幅を検出するために、Ansysソフトウェアを用いてハーモニックレスポンスシミュレーションを実行しました。その結果、19番目の設計で0.14432μmの変形が最も良い結果であることが分かりました。しかし、この結果は、最小目標値である1μmから5μmを達成することができず、ラッピングツールが振動しないことを示しています。このプロジェクトは目標に達しませんでしたが、改善策として、より軽い素材への変更、新しいデザインの作成、または超音波トランスデューサーの周波数の増加などがあります。
