Abstract

Advanced machining process telah terbukti dalam teknologi proses rekayasa untuk surface finishing dan proses material removal, atau dengan proses traditional finishing: fase fundamental, unrestrained, dan permintaan tinggi dalam fase tenaga kerja selama produksi. Finishing abrasif magnetik, pada polishing dalam proses non-konvensional mampu menyelesaikan dengan presisi dengan proses pemesinan yang dikontrol oleh medan magnet dan itu tidak berlaku untuk beberapa proses kompleks di mana teknik penyelesaian konvensional dapat dengan mudah diterapkan. Makalah ini mengulas teknik praktis untuk memoles bantalan AISI 316L ST Ball dengan proses finishing abrasif magnetik untuk menyelesaikan desain permukaan bola eksternal. Parameter input yang berbeda dari proses ditinjau seperti kecepatan elektromagnetik, arus dan tegangan langsung yang diinduksi, kepadatan fluks magnetik, jumlah ukuran partikel abrasif, lingkungan kerja, dan bahan benda kerja. Input yang terjadi untuk proses finishing bantalan bola stainless steel dapat memvalidasi kinerja laju material removal rate dan surface roughness.

Abstract

Most power plant process control concern on optimizing the power generation, reduce unplanned shutdown and reduce inventory cost. These challenges can be solved by implementing newly technology called Industry 4.0, which integrates the industrial internet of things (IIoT) and the cyber-enhanced systems as well as cloud computing. This paper presents a prototype system loop as an example of the power generation network to measure the rotating speed, number of turn and the frequency of vibration for the rotating device, humidity & temperature of the physical cooler or heater device within the plant in order to explain the interoperability principle of Industry 4.0 through the implementation of Power Plant 4.0. Base on the test results then used as a basis for identifying the challenges that will arise and the solution to implement Power Plant 4.0 with effectively and efficiently.
