Accurate manufacturing of bevel gears is an important problem for small workshops because the module milling cutters used for manufacturing are not accurate enough for the task. In this study, manufacturing of straight bevel gears is investigated by using end mills in CNC milling with a vertical machining center. By using this method, use of auxiliary apparatus, special cutters (such as the circular cutter, the rack cutter, etc.), and special machine tools are not required. For the study, first the straight bevel gear was modeled by Tredgold’s approach and manufacturing equations of the straight bevel gear were obtained. For the straight bevel gear manufacturing, a macro program was prepared and used. Afterward, the straight bevel gear was manufactured by using this program in a CNC milling machine, the Dyna 2900 machine. The results of the measurement data for a single tooth on the gear manufactured and the theoretical values are presented and discussed.

With ever increased demand for reduced sizes and increased complexity and accuracy, traditional machine tools have become ineffective for machining miniature components. Typical examples include dental implants, the parts used in mechanical watch movement, and the parts used in medical endoscope. With complex geometry and tight tolerance, few machine tools are capable of making them. This paper introduces our PC-based CNC Turn-Mill Machining Center. It has 5 axes, an automatic bar feeder, an automatic part collection tray, and a tool changer. In particularly, it has a special synchronization control algorithm that gives not only higher accuracy but also ease of use. In addition, to improve the accuracy, the software based volumetric error compensation system is implemented. Based on the experiment testing, the machining error is ± 3 µm in turning, ± 7 µm in milling and the maximum profile error is less than ± 7.5 µm in gear hobbing.

This paper presents a novel open architecture for a Precision CNC Turn-Mill Machining Center control system based on PC and Motion Control Card. A CNC Turn-Mill machining center is introduced. The hardware and software architecture is designed based on the concept of modularization. The implementation of key modules is given out. A rough interpolation algorithm with look-ahead function is introduced to improve the machining efficacy. The engineering verification proves that the system can fully meet the expected demands and easy to use.

The design and manufacturing of the rotary table with the specification Ø 170 mm (6 inches) for CNC machine 4 axis has been done. The objective of manufacturing a rotary table is to increase the efficiency of CNC machine Hardford 4 axis to be above 80% in line machining center CV. IM’s workshop. The engineering methods was taken, consist of: working preparation, manufacturing of working drawing, engineering process, the manufacturing and testing. The prototype has been tested and operated, the resulting of increasing productivity of which were as follows: the process of assembling was increased to be 3 time ( before 1 time) and processing time for a specific case reduced from 5 hours to 3 hours, number of operators for the case of assembling the rotary reduced to 1 person (before 4 persons), safety and security become to be better. The results show increased efficiency of CNC machine Hardford, from under 50% to be above 80%. Based on the economical analysis obtained by the cost of good sold (C.G.S) of the rotary table is IDR 34.060.000. The results presented in this paper is expected to be case study for developing a business of the metal and engineering SMEs domestic to the effort of improving efficiency, quality, productivity and competitiveness in global market.ABSTRAKPerancangan dan pembuatan alat bantu meja putar (rotary table) dengan spesifikasi teknis Ø 170 mm (6 inci) untuk mesin CNC 4 axis telah dilakukan. Tujuan pembuatan rotary table adalah untuk meningkatkan efisiensi mesin CNC Hardford 4 axis di atas 80% pada line machining center Bengkel CV. IM. Metode rancang bangun yang dilakukan, meliputi: persiapan kerja, pembuatan gambar kerja, proses engineering, pembuatan dan uji coba. Prototip tersebut telah diuji coba dan dioperasikan dengan hasil peningkatan produktivitas sebagai berikut: proses pengerjaan bongkar pasang meningkat menjadi 3 kali (sebelumnya 1 kali) dan waktu pengerjaan untuk kasus tertentu berkurang dari 5 jam menjadi 3 jam, jumlah operator untuk kasus bongkar pasang rotary berkurang menjadi 1 orang (sebelumnya 4 orang), keselamatan kerja dan keamanan menjadi lebih baik. Hasil peningkatan berupa efisiensi mesin CNC Hardford 4 axis dari sebelumnya di bawah 50% menjadi di atas 80%. Berdasarkan hasil perhitungan analisis ekonomi diperoleh harga pokok produksi (HPP) alat bantu meja putar adalah sebesar Rp. 34.060.000. Bahasan ini diharapkan menjadi contoh kasus bagi pengembangan usaha IKM logam dan mesin dalam negeri untuk meningkatkan efisiensi, mutu, produktivitas dan keunggulan daya saing di pasar global.Kata kunci: alat bantu meja putar, mesin CNC, harga pokok produksi

Masalah terletak pada rendahnya efisiensi mesin CNC : Mori Seiki dan Topper 920 pada line machining center di PT. ABC yang merupakan salah satu produsen berbagai jenis komponen otomotif di Indonesia. Tujuan peningkatan untuk memperoleh efisiensi mesin CNC di atas 80 % sehingga produk yang dihasilkannya mampu bersaing di pasar global. Cara peningkatan adalah melalui implementasi metode kaizen, yaitu : perbaikan terhadap standar kerja, secara selangkah demi selangkah dan terus menerus terhadap proses, yang melibatkan semua pihak baik pimpinan maupun karyawannya yang meliputi : (a) sistem penggantian dan penggabungan jig, (b) pembenahan pallet untuk jig, (c) perbaikan mesin dengan agen, (d) sistem clamping, (e) proses champering. Hasil peningkatan berupa efisiensi mesin Mori Seiki (dari 66 % menjadi 83 %) dan Topper 920 (dari 74 % menjadi 83 %).Kata kunci : kaizen, perbaikan, mesin CNC : mori seiki dan topper 920
