Abstract

Sling bearings are one of the important components in the cable car transportation system. These bearings function to support the weight of the cable car and reduce friction between the train and the rail/sling so that the train can move smoothly and safely. To produce quality sling bearings, a precise and accurate machining process is required. The manufacturing process of ropeway sling bearings goes through a machining process, where raw materials that are usually metals or metal alloys will be cut, shaped, and polished to form the desired bearing shape. Fixture machining is one of the most commonly used techniques in the machining process, where the workpiece is clamped or fastened to a specially designed fixture so that the workpiece remains stable during the machining process. The purpose of this engineering is to produce a fixture design for sling bearing components with increased quantity and quality of products on CNC machines by validating the design through simulation. In this study, tests were conducted using a conventional machining fixture and a machining fixture equipped with a pneumatic system. The test results show that the machining fixture equipped with a pneumatic system is able to increase the production speed and efficiency of cable car sling bearings by up to 20% compared to the conventional fixture. This research makes an important contribution to the cable car sling bearing manufacturing industry in improving production efficiency and final product quality. In addition, this research can also be a reference for further research on the optimization of the cable car sling bearing production process.

Abstract

PT.XYZ mengalami ketidak balancenya loding vs capacity pada produksi line assy caliper 2 dengan selisi produksi 13 pcs/jam selisi cycle time current terhadap take time adalah sebesar 2.1 detik data ini sesuai dengan laporan produksi line assy caliper 2 , Gap ini terjadi akibat proses clamping griper mesih dilakukan secara manual akibatnya banyak waktu Muda ( sia-sia ) pada proses tersebut. Sering terjadi part terjatuh , part susah dipasang dan dilepaskan sehingga berakibat proses jadi delay selama 2,1 detik laporan ini terlihat pada grafik monitoring problem line produksi assy caliper 2 . Dengan konsep melakukan penelitian dilapangan produksi langsung kemudian menganalisa kareteristik proses produksi diharapkan problem yang terjadi dapat dicarikan solusi untuk menghilangkan waktu MUDA ( Sia-sia ). Dari hasil penelitian ini membuktikan bahwa memodifikasi jig & fixture dengan pendekatan prinsip 6 Degree Of Freedom dapat menghilangkan gap produksi pada line assy calip er 2 sebesar 2,1 dtk atau 13 pcs /jam dengan cara merubah proses produksi manual menjadi Otomasi dan membuat jig & fixture pencekam benda kerja yang peneliti sebut Chuki-chuki Otomation. Hasilnya setelah dirubah system manual ke otomasi dengan menggunakan Chuki-Chuki pencekam proses loading dan unloading caliper di line assy caliper dapat dihilangkan sehinga bisa mengurangi waktu 1,5 dtk waktu loading dan unloading
