Abstract

Steel is one of the most widely used types of metal in the engineering field. There are many types of steel materials with different properties and characteristics, and steel materials can be used depending on their purpose. Steel contains various alloying elements. Although carbon is the element that has the greatest influence on the properties of steel, other elements cannot be ignored. The carbon content affects the mechanical properties of steel, such as hardness, ductility, formability, and other mechanical properties. This study aims to evaluate whether VCN 150 alloy steel can be used as an alternative material for cutting blades in plastic shredding machines based on its hardness value. The heat treatment process is conducted using varying temperatures of 800°C, 840°C, and 880°C, as well as using different cooling media, namely oil, seawater, and saltwater (25% salt content), then followed by a tempering process at temperatures of 100°C and 150°C. The research results indicate that the cooling medium significantly affects the hardness value of the material. A combination of a temperature of 800 °C and seawater cooling produces the maximum hardness value. The increase in hardness value becomes an alternative potential for plastic cutting blades.

Abstract

Surface defects of the workpiece and the emergence of sparks that suddenly enlarge during the flat grinding process cause a decrease in product quality and create unsafe working conditions. This study aims to identify the causes of surface defects of the workpiece on a flat grinding machine in the Polmanbabel advanced machining laboratory. Identification of the cause of damage using the five why analysis method. The study was preceded by defining the problem and then asking the question "why" to the problem and for each answer given approximately five times. To help answer each "why" question, an analysis of the system's working mechanism and a physical examination of the parts or components connected to the Wheelhead were carried out. The results of the study found that the root cause of the occurrence of defects on the surface of the workpiece and the phenomenon of sparks that sometimes enlarge suddenly and during the grinding process of the flat grinding machine was the destruction of the rubber components of the motor and spindle clutch. This case study also proves that the five’s why method can effectively identify the root cause of damage to the flat grinding machine.
