“…Based on Table 2, the approximate chatter stability is visualized through the stability lobe diagram (SLD), as shown in Figure 3. The boundary between a stable cutting process (without amplitude shifting) and an unstable cutting process (with amplitude shifting) can be visualized in a diagram called a stability lobe diagram (SLD) with spindle speed versus depth of cut [5], [6]. Using this SLD, certain combinations of machining parameters can be found with minimum chatter conditions so that the material removal rate will increase and the quality of the machining products will be better.…”

In the chatter, machining operations are undesirable because of the phenomena that affect product results, machining accuracy, tool life, and high operating value. Chatter is a vibration phenomenon that occurs in cutting tools due to the self-excitation of the influence of cutting parameters during the operation process of the machine. Types of chatter in machinery are regenerative and resonant. Because the pitch angles of variable helix tools vary, the helix angles of variable tools produce different tooth passing frequencies on each tool eye next to each other and can be used to prevent and control resonance. This study aimed to compare chatter control from the variable helix and regular-angle tools in the aluminum end milling process. The method is carried out through the end milling process experiment to determine the chatter control of the variable helix and regular-angle tools through the stability loop diagram. The results from this study were obtained by comparing control chatters in the milling process through controlling variable and standard helix angles as a guideline to produce the best surface roughness in the end milling process made from aluminum. The comparison of estimated control charts from variable helix tools is more comprehensive than regular helix tools.

“…The researchers employed a data retrieval process based on amplitude values to gather vibration data, a critical aspect of understanding the system's dynamic behavior. The use of FFT graphs [24] facilitated the analysis of frequency components present in the vibration data, providing a detailed view of the system's responses across different frequencies.…”

The study demonstrates a significant advancement in vehicle suspension testing by utilizing the Taguchi method for optimization. The suspension system determines a vehicle’s performance, directly affecting ride comfort, handling, and safety. The research presented in this study highlights a potentially effective method for enhancing suspension testing. The research systematically investigates the complex network of factors influencing suspension behavior using the Taguchi method, a robust optimization technique. The analysis includes examining road surface conditions, passenger weight variations, and tire pressure fluctuations. The objective is to design a suspension system that provides both comfort and stability without making any concessions, regardless of the obstacles encountered on the road. The car utilized for this research is an Altis sedan equipped with tires with a 205/55 R16 profile. The study’s findings indicate that factor A, which represents embankment height, significantly impacts 56 % of road irregularity management and the maintenance of a stable driving experience. The dynamic load factor (Factor D) contributes significantly to the vehicle’s overall stability and ride quality, accounting for 43 % in different scenarios. Based on the given framework, it can be observed that the variables B (tire pressure) and C (passenger weight) significantly influence suspension vibration, resulting in a reduction of below 0.1 %. While the research results presented here only cover a subset of automobiles, the methodology employed can be used to deal with similar problems in other vehicles.

Suspension is the most important thing that must be taken into account because it greatly affects driving comfort on the road. The working mechanism of the suspension consisting of spiral springs and shock absorbers is loaded vertically from the weight of the body, driver, and passengers. The uneven shape of the road surface in the form of potholes or bumps will greatly affect the comfort of the driver. This study aims to determine the effect of suspension work and the optimal value of vibration that occurs on one of the wheels of the vehicle against vertical dynamic loads. The method used in this study uses the Taguchi method which is used to determine the optimum dynamic load conditions against vibration in the suspension system.Â Â The characteristics used in this method are "Smaller is better". Several variables such as bump height, tire pressure on the wheels, as well as vehicle body weight and passenger weight are necessary factors to calculate optimal dynamic load conditions against vibration in the suspension. Based on the results of the optimum value conditions obtained, namely the height of the mound of 5 cm, tire pressure of 32 Psi, load of 84 kg, and dynamic load of 71 kg. From the results of the contribution rate to the ANOVA obtained, factor A (bump height) and factor D (dynamic load) are significant factors while factor B (tire pressure) and factor C (load load) are insignificant factors. Under optimal conditions, there was a decrease in suspension vibration value by 49.65%.
