Structural and Wear and Characteristic of Low Temperature Nitrided Stainless Steel
" An investigation to structural and wear behaviour of nitrided AISI 316 L stainless steel resulting from low temperature fluidized bed nitriding has been made in the present work It was found that the wear resistance of nitrided specimens was related to the formation of a preetpitation-free hardened layer on the austenitic surface. In the present laboratory experiments, the precipitation-free or S phase layer with a surface hardness of ~1350 H Va 5 was produced at ... "

Synthesis and experimental investigation of tribological performance of a blended (palm and mahua) bio-lubricant using the taguchi design of experiment (doe)
" The increasing prices of commercial lubricants and global attention towards a green environment have become the key issues to re-think about alternatives to commercially available lubricants. With these prospects in mind, vegetable oils can be utilized as an option to commercially available lubricants, due to their biodegradable and nontoxic nature. Moreover, they possess certain advantages like lower volatility and high flash/ fire points, higher viscosity index, excellent lubricity and cost savings. These properties of bio-lubricants ... "

The relationship between hardness and wear performance of particle-reinforced composite alloy = Hubungan antara kekerasan dan performa aus pada particle-reinforced alloy komposit
" ABSTRAK
Over the decades hardness is viewed to be one of the most prominent mechanical properties that has been wrought in numerous application throughout different the engineering industries, similarly to wear performance of a material. However, from previous research, the relationship between hardness and wear performance are somehow unintelligible. Therefore, further research focusing on evaluating if hardness is a reliable indicator to measure wear performance for particle reinforced composite alloys. This was based on previous research ... "

Pengembangan Sistem Kontrol Robotic Arm Manipulator untuk Pemantauan Keausan pada Mata Pahat Micromilling Berbasis Computer Vision = Development of Robotic Arm Manipulator Control System for Micromilling Tool Wear Monitoring Based on Computer Vision
" Proses pendokumentasian dan pengukuran untuk pemantauan keausan mata pahat (tool wear) micromilling membutuhkan ketelitian yang tinggi. Proses ini menggunakan mikroskop digital Dino-Lite untuk mengambil gambar dan dilakukan secara berulang setiap setelah melakukan pemesinan dengan cara melepas mata pahat dari spindle pada mesin micromilling. Maka dari itu dilakukan pengembangan robot manipulator untuk mempermudah proses pemantauan mata pahat micromilling. Pengendalian pergerakan aktuator servo dan motor stepper pada pengembangan sistem kontrol robot manipulator dilakukan dengan menggunakan microcontroller board ... "

Pengembangan Sistem Mekanikal Robotic Arm Manipulator Untuk Pemantauan Keausan Pahat Micromilling Berbasis Computer Vision = Development of Robotic Arm Manipulator Mechanical System for Micromilling Tool Wear Monitoring Based on Computer Vision
" Keausan mata pahat menjadi masalah utama dalam industri manufaktur ketika proses pemesinan karena keausan mata pahat menjadi pengaruh besar dalam kualitas produksi. Terdapat dua metode pemantauan tool wear, yaitu direct dan indirect. Direct tool wear monitoring merupakan metode pemantauan dengan melakukan pengukuran tingkat keausan mata pahat secara langsung pada proses pemesinan. Penelitian ini mengembangkan sistem manipulator sebagai robot inspeksi yang memiliki fungsi menggerakkan Dinolite sebagai alat bantu pemantauan keausan mata pahat secara visual. Penelitian ini ... "
