Pure molybdenum, titanium-circonium-molybdenum (TZM) and molybdenum-aphnium-carbon (MHC) alloys are the main molybdenum alloys that are widely used in the industry. These materials are used in many different industries, mainly in the defense and aviation industries. The final processing operations with low slurry amounts are critical manufacturing processes due to the need to obtain a qualified surface geometry. Due to the demand for high surface quality and size accuracy, it is important to pre-identify and optimize the parameters affecting the final processing. Therefore, processing parameters such as the cutting speed, the amount of progress, the thickness of cutting and the cutting equipment and geometry must be identified. In this study, the aim is to determine the cutting strength and cutting parameters appropriate for the freezing process of three different molybden alloys and the average surface smoothness. The tests were conducted using the Taguchi L16 vertical directory. Variance analysis (ANOVA) has been applied to determine the importance levels of the cutting parameters on the basic cutting force (Fc) and the average surface smoothness (Ra) values obtained as a result of the experiments. The optimum values of the variables obtained using the signal/rise ratio are found at different levels for the basic cutting force and the average surface smoothness. According to ANOVA analysis, the most important variable for cutting forces is the progress amount and the most important variable that affects the surface smoothness is the cutting speed.
