“…Setelah proses perakitan maka pisau bagian atas akan bergerak maju mundur secara horizontal sedangkan pisau bagian bawah akan diam/tetap. Suatu produk akan memberikan fungsi jika produk tersebut dirakit menjadi satu kesatuan dengan mengikuti suatu urutan proses perakitan [10]. Pada proses perakitan system pemindah daya dan pisau pemotongan dilakukan beberapa tahap dari proses persiapan bahan dan alat, proses pengelasan penyambungan, dan proses penggaabungan/assembly, sehingga mendapatkan hasil seperti gambar di bawah ini: Gambar 10.…”

Tarum (Indigofera) farmers, especially those in Subang Regency, West Java Province, still use manual harvesting methods. Seeing these conditions, it is necessary to carry out new innovations in the indigofera plant industry, which is expected to be able to help ease and speed up the harvesting process. The innovation is to make a cutting tool for tarum plants (Indigofera) with an auto cutting system. In the process of selecting tools, materials and machining must be in accordance with the needs, because this will determine the final result of the product. The manufacturing process uses several steps of the work process, namely, measuring, cutting, joining materials and turning. The manufacturing process of tarum cutting tools (Indigofera) with an autocutting system, includes reading the design drawings, making work preparations, identifying tools and materials used, measuring materials, cutting materials, drilling materials, joining by welding, as well as the results of the cutting knife manufacturing process. and power transfer system. With the dimensions of the upper blade 930 mm long, 60 mm wide, and 3 mm high. The lower blade is 1000 mm long, 60 mm wide and 7 mm high. Power transfer system with axle dimensions of 220 mm x 20 mm. The cover plate of the upper and lower crutches is 140 mm x 140 mm, 12 mm thick. Central crutch cover pipe 113 mm x 59 mm. In testing the performance of the Tarum (Indigofera) cutting tool with the autocutting system, the tool was tested in two stages of testing. The results of testing the knife in cutting the leaf stem are functional, but the knife changes shape due to cutting thick stems, and the power transfer system can reduce the 6800 rpm figure from the motor to 4500 rpm to the knife optimally.

“…From the deviation simulation, if the geometry tolerance allocated to the surface of the two features is the surface accuracy (surf), the maximum (Ros max ) and minimum (Ros min ) deviations of the MOS and MBS features can be calculated by the following equations: The accumulated tolerance/total tolerance (Tt) on the air gap is calculated using the worst-case method, with the following equation: (15) where ±T𝑅𝑇𝑖 is the tolerance value of the i th dimension in equal-bilateral format.…”

“…Tolerance stack-up analysis is a method used to determine the cumulative effect of tolerances allocated to the features of a component and to ensure that the cumulative effect is acceptable to ensure product functionality after an assembly process [15]. The tolerance stack-up analysis method is generally divided into two basic methods, namely the worst-case (WC)-based and statistical-based analysis or also known as the root sum of the square (RSS).…”

Mechanical tolerance is something that should be carefully taken into consideration and cannot be avoided in a product for manufacturing and assembly needs, especially in the design stage, to avoid excessive dimensional and geometric deviations of the components made. This paper discusses how to determine and allocate dimensional and geometric tolerances in the design of a 10 kW, 500 rpm radial flux permanent magnet generator prototype components. The electrical and mechanical design results in the form of the detailed nominal dimensions of the generator components, and the allowable air gap range are used as input parameters for tolerance analysis. The values of tolerance allocation and re-allocation process are carried out by considering the capability of the production machine and the ease level of the manufacturing process. The tolerance stack-up analysis method based on the worst case (WC) scenario is used to determine the cumulative effect on the air gap distance due to the allocated tolerance and to ensure that the cumulative effect is acceptable so as to guarantee the generator's functionality. The calculations and simulations results show that with an air gap of 1 ± 0.2 mm, the maximum air gap value obtained is 1.1785 mm, and the minimum is 0.8 mm. The smallest tolerance value allocation is 1 µm on the shaft precisely on the FSBS/SRBS feature and the rotor on the RPMS feature. In addition, the manufacturing process required to achieve the smallest tolerance allocation value is grinding, lapping, and polishing processes.
