“…Pada saat kita memulai untuk membuat alur (grooving) di mesin bubut, jika kita menggunakan putaran mesin bubut dalam kondisi putaran (rpm) yang tinggi akan menyebabkan kerusakan/ gompal pada benda kerja yang sedang kita kerjakan maupun pahat yang kita gunakan. Karena pada dasarnya sistem pengerjaan untuk membuat sebuah alur (grooving) umumnya pahat tersebut membuat alur secara vertikal atau dari depan (in the front), tapi perlu juga diperhatikan tingkat pemakanan (feeding), ini bertujuan agar pahat grooving (alur) tidak mudah patah dan hangus [6]. Berdasarkan hasil observasi yang dilakukan yaitu jenis fixture yang digunakan masih menggunakan beberapa susunan balok kayu serta stopper sebagai penunjang dan penopang part suction cover ketika melakukan proses Grooving.…”

Centrifugal pumps have a design consisting of an impeller rotor and an inlet channel in the middle. When the rotor of impeller rotates, the fluid will flow into the casing due to the centrifugal force. Suction Centrifugal pump casing is designed in the form of a diffuser that surrounds the pump impeller. This diffuser is more commonly known as the volute casing. In accordance with the function of the diffuser, the volute casing serves to reduce the flow velocity of the fluid entering the pump. The stopper is a fixture that is used as a support for the suction cover part during the grooving process. Stopper is used so that the surface turning results are not oval . Grooving is a process to form a groove on a workpiece by using a lathe or milling machine and others . To give the results of the groove surface on the suction cover, it is necessary to carry out a grooving process. The grooving process is used to smooth the grooves on the suction cover surface. However, because the diameter of the suction cover is quite large, an additional fixture is needed to support the suction cover so that it remains in an even position during the grooving process. The stopper is important thing in the process of grooving suction cover type E-100 50 with a spindle speed of 180 rpm. The dimensions of the proposed stopper are 155.88 mm long, 150mm wide, and 150m high. So this stopper fixture must be strong and stable during the machining process. The purpose of this paper is to propose a 3D fixture design during the process of grooving the suction cover E 100 50. This research was carried out theoretically using data machining and parts obtained during observation. Compilation of observational data in the form of images and strength analysis in 3 dimensions using Autodesk Fusion 360 software. The results of this study are divided into 2 parts, 3D design and strength analysis including von mises stress, displacement and safety factor. From the results of the simulation von mises in picture 8, it shows that the stress that occurs is 32.59 MPa at the most critical part. The critical part is the upper support section which is the center of support. From the results of the simulation displacement in picture 9 it shows that the change (displacement) in the design stopper maximum so that deformation occurs, which is indicated by a red color of 0.002668mm. Changes above 1mm the material will break. This shows that the shape and dimensions of the stopper are said to be in the safe category. From the picture of the results of thesimulation Safety Factor in picture 10, it shows that the value of the safety factor for a sufficient level of safety is 6.353. If it is less than the value of the safety factor, the material has been deformed or broken because the maximum stress is comparable to or greater than the yield strength of the material.

“…Ehmann et al proposed a purely analytical approach, based on the common normal vectors at the points of contact must intersect the axis of wheel, to calculate the profile of wheel [1]. Li discussed the relationship between the interpolation methods and the precision of flute fitted curve [2]. Sometimes the profile of flute is generated by the combination of non-enveloped and enveloped curves.…”

The flute plays an important role in the design process for tools. The complexity of the cutting edge is increasing continuously. Thus, it is difficult to grind flute precisely and efficiently. This paper presents a practical grinding method for the flute of tools. It solves the issue that how to grind the flute with the complex edge by standard wheels.It is summarized as follows: the curve of cutting edge and core are used as the designed parameters of the flute; We propose the fundamental conditions that the wheel doesn't interfere with designed parameters; We can find the posture and position of wheel in the curve frame easily, thus obtain wheel trajectory. Finally, using a taper end mill as an example, the results show a good agreement between the CAM data and the model data. This proves the effectiveness of this method.

“…This method firstly solved the forming sand profile from the given screw rotor profile, and then figured out the screw rotor profile from the forming wheel profile, thus realizing the screw rotor profile precision forming grinding simulation. Li [6] proposed a novel calculation process based on the end milling cutter spiral groove machining principle to compute the grinding wheel profile with a known groove model and grinding wheel axis setting parameters. Hoang et al [7] established a general mathematical model for internal-meshing honing for screw rotors.…”

Characterized by a complex contour profile involving arc, cycloid and involute, etc., the screw rotor is usually manufactured by a forming tool. The finished surface quality and efficiency of the screw rotor are determined by the cutting performance of the forming tool. However, the machining performance of the forming tool is closely related to the structure shape of cutting edge, which is then determined by the installation parameters of the forming tool. Therefore, to make the cutting performance of forming tool controllable, it is essential investigate the relationship between the cutting performance of the forming tool and its installation parameters at the design stage. In this paper, a novel installation parameter optimization design method of forming tool for screw rotor is presented. A parametric optimization program is designed to finalize the range of installation parameters satisfying the spatial meshing relation and machining equipment parameters. The profile characteristics of forming tool under different center distances and mounting angles have been investigated. For validation, several screw rotors were ground in experiments and the resulted profile errors were analyzed. The results show that the cost of precision grinding of screw rotor can be significantly reduced, without compromise of machining quality. As such, the proposed design method could serve as a promising platform to faciliate screw rotor manufacture.
