Statistical Analysis of Cutting Force and Vibration in Turning X5CrNi18-10 Steel

Abstract

X5CrNi18-10 is a corrosion-resistant steel that has become popular in the automotive, marine, food, nuclear, and other industries. Chromium alloyed in the X5CrNi18-10 increases the material’s toughness, which influences the cutting phenomena such as the cutting force and vibration. It is necessary to investigate the effect of the machining parameters on the X5CrNi18-10 turning, particularly the feed, which has significant effects on the cutting phenomena. The objective of this research is to investigate the correlation between the feed and cutting phenomena to improve the product quality, reduce machining disruptions, and optimize the parameters for a low cutting speed and vibration. Statistical analysis has shown promise in identifying the impact of variables using correlation analysis and estimated marginal means plots. This study highlights the findings of the Pearson’s correlation analysis between the feed, active cutting force, and active vibration as well as the estimated marginal means plots between the machining parameters and cutting phenomena. The results indicate that there is a strong correlation between the feed and active cutting force with a coefficient of correlation of 0.688, as well as the feed and active vibration with a coefficient of correlation of 0.697. The estimated marginal means plots indicate that as the cutting speed increases, the value of the active vibration and the active force decreases.

Investigating the impact of vibration characteristics on the surface roughness using MPU6050 sensor at turning of 11SMn30 steel

Abstract. Manufacturing system automation is becoming more and more important in sectors due to the growing digital revolution (Industry 4.0) and economic competitiveness. One of the key criteria for making machines entirely automatic is the installation of sensors on the machine. Industrialists have used speed, temperature, and other sensors to offer real-time data and examine faults but sensors to interpret vibration are still being developed. One of the primary impacts of vibration is on the surface roughness. Surface roughness has an impact on several factors affecting the machine, including stress concentration, frictional wear, corrosivity, and so on. To prevent such failures, this study focused on identifying a correlation between vibration and surface roughness by adjusting the feed rate and it was found 92.2 % correlation is noted in between vibration and arithmetic average surface roughness.

CORRELATION ANALYSIS BETWEEN COMPONENTS OF FORCE AND VIBRATION IN TURNING OF 11SMN30 STEEL

Abstract. Workability of material is defined as the ease of operating on it. 11SMn30 is widely used material in automobile manufacturing industries. Cutting forces have been shown to be the most effective measure for understanding metal machining processes. The forces which helps in performing machining operation also affects the cutting tool, in terms of deformation, bend, wear, which leads to the vibration in the machining system, This article aims to study the correlation between feed, components of cutting forces and components of vibration in turning of 11SMn30 steel grade using dynamometer and MPU6050 sensor.

Keywords: Turning operation, Cutting forces & Vibrations, Correlation, Analysis of Variance

ANOVA and Correlation Analysis of Feed, Cutting Forces and Tool Vibration in 11SMn30 Steel Turning

Abstract. The shift towards industry 4.0 in automative parts manufacturing and cloud machining solutions requires an understanding of materials machinability. To manufacture high quality products feed, cutting forces and tool vibration are important machining parameters that their dependence on one another other needs to be identified. This paper studies the Pearson correlation between feed, cutting forces and tool vibration and ANOVA is calculated to verify the validity of model. 11SMn30 a widely used steel grade for manufacturing shafts was used in the current study because of its very good machinability. The results suggests that feed rate influences both cutting forces as well as vibration in tool which has an overall effect on product quality.

Keywords: 11SMn30 Steel Grade, Machinability, Cutting Forces, Tool Vibration, Correlation Analysis, ANOVA.

Model Justifying Existence of 33 million Gods

Abstract: Beyond the grasp of our understanding lie enigmatic forces, whose presence is felt and measured, yet their origins remain elusive and mysterious. Despite our inability to fathom them, we cannot refute their existence. This article discusses the possibility of the existence of 33 million gods or more in Hinduism, which is often associated with polytheism. The article cites literature that explores how energy can be transformed from one form to another, and how special shapes can be used to efficiently isolate energy. The article also discusses the use of mantras and how they generate certain frequencies that can help in various aspects of life. The article proposes a model that suggests that the energy generated by people, which is converted into sound energy, can be conserved in an isolated room and can act as a reservoir of energy. It is argued that this energy can be the basis for the existence of many gods in Hindu mythology, and that the architecture of temples and the use of mantras can contribute to the conservation and concentration of this energy.Read Full Article Here
