Abstract

Cutting forces analysis of turning process are one of the mandatory lecture contents given in mechanical and manufacturing department. It is because they are related to the quality of the product produced. Therefore, being able to observe and interpret cutting forces can provide an overview of machining quality of the machine. This experimental research explored the effect of spindle rotational speed on cutting process using a full octagonal shaped rings dynamometer made in the laboratory. The results showed that increasing the spindle rotation speed affected the cutting time, whether the greater the spindle rotational speed used, the faster the turning process were completed, each of which is 312.5; 156.25; and 112 seconds. However, variational of spindle rotational speed did not affect the cutting forces of turning process even though the cutting force graph showed fluctuations. Those are due to the dynamics of the machining process. Spindle rotational speed also influenced the frequency content of the process. Various characteristic frequencies of the turning process could be observed, including the spindle rotation frequency (fs) and harmonic frequencies.

Abstract

Cutting forces are parameters that can be used to optimize the machining process, analyze power consumption, and affect temperature during the lathe process. Measurement of cutting forces using a dynamometer and temperature using a thermocouple is quite expensive. This article discusses the effect of machining parameters on cutting force and temperature on AISI 304 steel workpiece material with carbide insert tool. The method used to analyze cutting forces and temperatures is based on the finite element method (FEM). The results show that the cutting force fluctuates due to the influence of depth of cut. The greater the value of the depth of cut used, the greater the axial cutting force and tangential cutting force. While the temperature does not change due to variations in depth of cut. Cutting speed variations do not significantly affect the cutting force, but affect the cutting time and temperature. The greater the cutting speed value used, the greater the temperature produced and the less cutting time required.

Abstract

Cutting forces in turning process are usually measured using dynamometer and they can be used to evaluate the quality of the cutting process. Commercial dynamometers on the market today offered with quite expensive prices. Therefore, many researchers are trying to design dynamometers at more affordable prices. One of the most important components in designing a dynamometer is tranducer. This article discusses the design and static and dynamic analysis of a full octagonal shaped ring tranducer for measuring cutting forces in orthogonal cutting. The tranducer design is analysed statically using the Finite Element Method (FEM) and dynamically using the Experimental Modal Analysis (EMA) method to determine its structural strength. The results of the static analysis of the strength of the tranducer structure were able to withstand static loads of 224 to 388 N. It is because the tranducer stress did not exceed the yield strength of the material which is 233 MPa. While the dynamic analysis of the tranducer structure using EMA shows that the natural frequency, the damping ratio, the stiffness constant, the modal mass, and the damping coefficient 3851 Hz, 18.5 x 106 N/m, 1.04%, 32 g, and 16 N/s/m, respectively. With these dynamic parameter, the tranducer design for this low-cost dynamometer is safe and reliable when used in the turning process with spindle rotation speeds reaching 20 Krpm.
