This work aims to conduct theoretical and experimental studies on the energy and force parameters of the separation process, as well as the geometric accuracy of the separated tubular workpiece using the "eccentric twisting" method. A mathematical model of a device with a "crank-circular" mechanism for cutting pipes by "eccentric twisting" has been developed. The technological process of cutting pipes by "eccentric twisting" was simulated using the DEFORM-3D software package. The results of experimental studies are in good agreement with the theoretical data calculated using the proposed mathematical model and the specialized program DEFORM-3D. The maximum differences between the cutting torque values obtained theoretically and experimentally do not exceed 6%. For the industrial implementation of research results, a design of an installation with a wedge-hinged drive with a concave wedge in combination with a "crank-circular" mechanism for separating pipes by the "eccentric torsion" scheme is proposed.

“…Beberapa tahun terakhir, pipa baja tahan karat berdinding tipis telah digunakan semakin luas di industri permesinan. Yang disebut stainless steel berdinding tipis adalah sejenis pipa baja tahan karat yang perbandingan ketebalan dinding dan diameter luarnya tidak lebih dari 6% [1,2]. Dengan pesatnya perkembangan industri manufaktur mesin modern, persyaratan efisiensi produksi dan akurasi pemesinan pada produksi pemotongan pipa baja meningkat secara bersamaan [2,3].…”

Mesin pencoak pipa (pipe notcher) yang ada di pasaran saat ini harganya cukup mahal sehingga banyak bengkel-bengkel kecil masih menggunakan cara konvensional untuk melakukan pencoakan pipa. Cara yang biasa digunakan adalah dengan menggunakan gerinda tangan, sehingga membutuhkan waktu yang lama dan hasilnya kurang presisi. Untuk itu pada penelitian ini dirancang mesin pencoak pipa dengan memanfaatkan sabuk amplas sebagai V-belt yang dihubungkan dengan poros dan digerakkan oleh motor listrik. Kemudian benda kerja didekatkan pada poros matras dan selanjutnya ditekan maju sampai terbentuk profil yang diinginkan. Rancang bangun mesin pencoak pipa multi dimensi ini terbagi dalam tiga tahap. Tahap pertama konsep desain dan perencanaan komponen, dilanjutkan dengan tahap pembuatan dan terakhir adalah pengujian mesin. Dari hasil rancang bangun diperoleh bahwa mesin pencoak pipa multi dimensi ini menggunakan motor listrik 0,5 HP dan putaran 1400 rpm sedangkan rangka mesin menggunakan besi siku ukuran 4 x 4 cm. Setelah dilakukan pengujian, mesin dapat bekerja dengan baik. Untuk mencoak pipa dengan diameter 3/4 inch dibutuhkan waktu selama 0,335 menit, sedangkan untuk pipa ukuran 1 inch membutuhkan waktu selama 1,075 menit. Sedangkan profil yang dibuat menggunakan mesin ini mampu membentuk sudut antara 0° sampai dengan 30°. Pipe notcher on the market today are quite expensive so that many small workshops still use the conventional method for cutting special pipe profiles. The method commonly used is to use hand grinding, so it takes a long time and the results are less precise. For this reason, in this study was designed a pipe notcher machine using the sandpaper belt as a V-belt connected to a shaft and driven by an electric motor. Then the workpiece is brought closer to the mattress axis and then pressed forward until the desired profile is formed. The design of this multidimensional pipe notcher engine is divided into three stages. The first stage is the design concept and component planning, followed by the manufacturing stage and the last stage is machine testing. From the design results, it is found that this multi-dimensional pipe notcher machine uses an electric motor 0.5 HP and a rotation of 1400 rpm while the engine frame uses 4 x 4 cm angle iron. After testing the machine can work properly. To check a 3/4 inch pipe it takes 0.335 minutes, while for a 1 inch pipe it takes 1.075 minutes. Meanwhile, the profiles made using this machine are capable of forming angles between 0 ° to 30 °.

“…Manual cutting of thin tubes is discussed in [26] using the sharp hardened cutting wheels as manual tools. Moreover, the problems such as; an unacceptable level of material waste, low production efficiency and the difficulties of clamping, in addition to large size deviation in the cutting process are discussed in [27]. Some of these problems can be treated via planetary cutting technique with the usage of two symmetrical sharp cutting wheels.…”

Design for Six Sigma (DFSS) is a proactive approach that aims at designing in quality during the early stages of product or process development. In this paper, the DMADV (Define-Measure-Analyze-Design-Verify) methodology has been applied to an industrial process. The considered application involves cutting tubes to predefined lengths in order to be supplied to custom-made automotive exhaust tube manufacturers. Investigating the process reveals several problems that adversely affect the production. Accordingly, customer requirements have been identified and the Quality Function Deployment (QFD) has been implemented to translate these requirements into technical characteristics. A conceptual design of a compound mechanism for both feeding and cutting has been suggested to overcome the drawbacks in the current practice. A detailed 3D CAD model has been developed, in addition to a prototype that has been manufactured to test the validity of the proposed design. Pilot runs of the prototype reveal that the developed mechanism not only performs its intended task adequately, but also the chances of cutting wrong tube lengths have been eliminated.
