Abstract

Tool life merupakan aspek penting dalam proses pemesinan karena berpengaruh terhadap kestabilan proses, kualitas permukaan benda kerja, dan biaya produksi. Dalam praktik industri, pengujian tool life secara eksperimental sering kali sulit dilakukan akibat keterbatasan waktu dan tuntutan produksi, sehingga penentuan tool life umumnya didasarkan pada kebijakan operasional dan data historis perusahaan. Saat ini PT.X menerapkan special tool pada proses pemesinan flange hole komponen starter bracket dengan standar tool life sebesar 10.000 pcs per tool. Penelitian ini bertujuan untuk menentukan tool life dan cutting speed optimal menggunakan persamaan Taylor dengan pendekatan minimum unit cost, serta membandingkan tool cost per piece antara kondisi minimum unit cost dan kondisi existing perusahaan. Analisis dilakukan berdasarkan data aktual proses pemesinan tanpa mengganggu aktivitas produksi. Hasil penelitian menunjukkan bahwa cutting speed optimal sebesar 210 m/min menghasilkan tool life 339 menit, lebih panjang 102% dibandingkan kondisi existing dengan cutting speed 250 m/min yang menghasilkan tool life 167,96 menit. Kondisi minimum unit cost juga menghasilkan penurunan tool cost per piece sebesar 41,03% pada flange hole 1 dan 41,10% pada flange hole 2, serta penurunan total machining cost sebesar 10,84% dan 21,25% pada masing-masing flange hole.

Tool life is an important aspect in machining processes as it affects process stability, workpiece surface quality, and production costs. In industrial practice, experimental tool life testing is often difficult to conduct due to time constraints and production demands, so tool life determination is generally based on company operational policies and historical data. PT.X currently applies special tools in the machining process of flange holes on starter bracket components with a standard tool life of 10,000 pcs per tool. This study aims to determine the optimal tool life and cutting speed using the Taylor equation with a minimum unit cost approach, as well as to compare the tool cost per piece between the minimum unit cost condition and the existing company condition. The analysis was conducted based on actual machining process data without disrupting production activities. The results show that the optimal cutting speed of 210 m/min produces a tool life of 339 minutes, which is 102% longer than the existing condition with a cutting speed of 250 m/min that yields a tool life of 167.96 minutes. The minimum unit cost condition also produces a reduction in tool cost per piece of 41.03% for flange hole 1 and 41.10% for flange hole 2, as well as a reduction in total machining cost of 10.84% and 21.25% for each respective flange hole.
