Optimization of Cutting Conditions in Hard Turning Steel AISI 4340 Using Layed CVD Carbide Laips (Al2O3/TICN) with the Simulated Annealing Method

Introduction

The hard machining process, which involves turning steel materials that have been hardened to above 45 HRC, requires special attention. In this process, the volume of material removed or the volume of removal material (VMR) is an important indicator of productivity. To increase the efficiency of this process, carbide chisels, especially layered chisels such as aluminum oxide (Al2O3) and Titanium Carbon Nitride (TICN), are widely used. This Al2O3/TICN CVD chisel is proven effective in cutting AISI 4340 steel, which has a high level of hardness.

The Importance of Simulated Annealing in Optimization

Simulated Annealing (SA) is a strong algorithm that is easy to implement for material simulation. Based on the principle of probability and statistical mechanics, this algorithm is used to find optimum solutions, both global and local solutions, on various problems. The performance of Simulated Annealing is measured based on certain function values that evaluate several temporary solutions produced. In the context of cutting conditions optimization, SA is used to find the optimal combination of cutting parameters that can increase productivity while maintaining surface quality.

The Role of Matlab in Optimization

Matlab, or Matrix Laboratory, acts as a tool for analysis and computing numerical data that is very much needed in this study. With a broad ability to carry out mathematical operations, matrix-based programming is often used for numerical computing techniques, including optimization and approximation. In this context, Matlab is used to analyze various cutting conditions that can increase productivity. The use of Matlab allows for the simulation of different cutting conditions and the evaluation of their effects on productivity and surface quality.

The Importance of Productivity in Metal Cutting

Productivity in metal cutting is closely related to the capacity to produce large amounts of products and of good quality. To achieve high results, a high removal rate (MRR) and Time Loss (TL) material is needed, which in turn will increase the VMR value. However, it is important not to ignore the quality of the final surface of the product. Optimization of cutting conditions is needed to achieve a balance between productivity and surface quality.

The Optimization Process

The optimization process involves the use of Simulated Annealing to find the optimal combination of cutting parameters that can increase productivity while maintaining surface quality. The cutting parameters that are optimized include cutting speed (V), feed rate (f), and cut depth (A). The optimization process is carried out using Matlab, which allows for the simulation of different cutting conditions and the evaluation of their effects on productivity and surface quality.

Results of the Study

The results of this study indicate that the highest VMR value obtained through optimization is 369,939 cm³ with a cutting speed (V) of 90.00 m/min, feed rate (f) of 0.15 mm/rev, and cut depth (A) of 2.00 mm. This cutting condition is considered an optimum condition that can produce high productivity.

Conclusion

By understanding this optimization process, industry can increase efficiency and effectiveness in hard engineering, especially in cutting high quality steel such as AISI 4340. This approach is not only relevant to increase output, but also contributes to the development of better and more durable cutting tools, thereby reducing the frequency of replacement of tools and production costs. In an increasingly competitive world, innovation in cutting techniques like this will be the key to the success of the company in meeting the needs of the market that continues to grow.
