Tóm tắt
With the rising need to promote productivity that is based on quality, energy, and cost, it is imperative that cutting tools are not just selected on the basis of its suitability, but on its efficiency. It is particularly important that workpiece materials are aligned to specific cutting tools, to improve manufacturing costs, lead time, and quality of the overall product and to create flexibility. For this reason, a comparative study of the performance of high-speed steel and tungsten carbide cutting tools has been performed to determine the most suitable for the machining of a 304 Austenite Steel cylindrical bar. The tool wear of the cutting tools was selected as a measured to ascertain their performance in the turning operation. Response surface methodology was employed to analyzing the results and determining their optimal performance. From the study, the tungsten carbide tool recorded optimal parameters as follows: cutting speed 1303 m/min, feed rate 0.354 mm/rev, and depth of cut 0.458 mm with a tool wear of 1.173 mm and for the high-speed steel tool, cutting speed 1321 m/min, feed rate 0.208 mm/rev, and depth of cut 0.682 mm with a tool wear of 2.073 mm. The study judging from the tool wear shows the efficiency of the tungsten carbide tool over the high-speed steel cutting tool, as it can be seen from the results obtained that the lowest tool wear in the turning of the cylindrical steel bar is recorded from the use of the tungsten carbide cutting tool. From the 3D surface plots, it can be confirmed that to obtain a good performance from the different cutting tools, the cutting speed best suited for the cutting tool must be taken into consideration.
