“…The largest S/N ratios always yield the optimum quality with the minimum variance. 5 Therefore, the level with the largest value determines the optimum level of each factor. From Figures 3 and 4, relating to the milling of the TiC-coated convex and concave inclined surfaces, the optimum levels in terms of the tool acceleration can be observed at A4 for V c (100 m/min), B1 for V f (223 min -1 ) and C1 for f p (0.8 mm).…”

“…Ramping and contouring are inevitable choices of the tool-path styles for the implementation of the up-milling and downmilling strategies. 5 In the ramping tool-path styles, the cutter scans an inclined surface following the lines in parallel to the surface radius. On the other hand, in the contouring tool-path styles, the cutter scans an inclined surface following the lines perpendicular to the surface radius.…”

“…In order to determine the right cutting-tool values (Table 1), a number of experiments for each tool coating was conducted based on the reference values. 5 The cutting- Inclined surfaces and related cutter path styles: CUM-1 (upward step over), CDM-1 (upward step over), CUM-2 (downward step over), CDM-2 (downward step over), RUM-1 (left step over), RDM-1 (left step over), RUM-2 (right step over), RDM-2 (right step over) tool step-over values directly affect the tracks on the surface made by the cutter, the load on the cutter and processing time. 8 The step-over value was chosen to be 5 % of the tool diameter and this value was set as the lower level of fp.…”

“…The material is commonly used in tool-making processes due to the quality characteristics including high durability, high thermal conductivity, high machinability and high cracking resistance. 5 First, experimental samples of (40 × 30) mm islands on a (220 × 135 × 50) mm block were machined. In the experiments, an indexable cutter body of an Ø16 mm cylindrical shank (CoroMill, R216-16A20-045) with a twofluted 30°-helix-angle end mill was used.…”

“…Therefore, generating the optimum cutting parameters is crucial to obtain high productivity in the manufacturing process of complex geometries and to reach the desired tolerance values. 4,5 The studies carried out in the field commonly focus on: 1) the effect of cutting parameters and cutting strategies of plain-surface milling, 2) analytical tool-acceleration calculations and measurements for end-milling and turning operations. W. H. Yang and Y. S. Tarng 6 worked on the optimization of the cutting parameters for turning operations so that both optimum cutting parameters were demonstrated and the basic cutting parameters affecting the cutting performance in turning were defined.…”

The determination of the cutting-parameter values that cause increases in vibration values is important to minimize the errors that can occur. Thus, the first aim of this study was to investigate the optimum cutting-parameter values and tool-path strategies in ball-end milling of the EN X40CrMoV5-1 tool steel with three coated cutters using the Taguchi method. The parameters taken into consideration are the cutting speed, feed rate, step over and tool-path strategies. The second aim of the study, a model for the tool acceleration as a function of the cutting parameters, was obtained using the response-surface methodology (RSM). As a result, the most effective parameter within the selected cutting parameters and cutting strategies for both inclined surfaces and different coatings was the step over. In terms of tool coatings, the most deteriorating coating for the tool acceleration on both inclined surfaces was the TiC coating. In addition, the response-surface methodology is employed to predict the tool-vibration values depending on the cutting parameters and tool-path strategy. The model generated gives highly accurate results. Keywords: inclined surfaces, ball-end milling, tool acceleration, Taguchi method, response-surface methodology, response optimization Neoptimalni rezalni parametri med mehansko obdelavo lahko povzro~ijo ne`elene vibracije in posledi~no napake. Prvi cilj avtorjev te {tudije je bil dolo~iti optimalne vrednosti rezalnih parametrov in strategije potovanja orodja med mehansko obdelavo orodnega jekla EN X40CrMoV5-1 s krogli~nim frezalom s tremi rezili z razli~no prevleko (TiC, TiN in TiAlN). Za to so uporabili Taguchi-jevo metodo. Parametri, ki so jih avtorji zajeli v {tudiji so bili: hitrost rezanja, velikost odvzema, korak odvzema (preskok) in strategija poti orodja. Drugi cilj avtorjev te {tudije je bil izdelati model pospe{evanja orodja v odvisnosti od rezalnih parametrov, z uporabo metodologije odziva povr{ine (angl. RSM). Ugotovili so, da je korak odvzema (angl.: step over) naju~inkovitej{i parameter med izbranimi rezalnimi parametri in rezalnimi strategijami, tako za oba izbrana nagiba (ukrivljenosti) povr{ine, kot tudi izbrane trde prevleke. Med izbranimi trdimi prevlekami se je v vseh pogojih frezanja kot najslab{a izkazala TiC prevleka. RSM metodologija dodatno omogo~a napoved vibracij orodja v odvisnosti od rezalnih parametrov in izbrane strategije poti orodja. Izdelani model daje zelo to~ne rezultate. Klju~ne besede: nagib (ukrivljenost) povr{ine, mehanska obdelava s krogli~nim frezalom, pospe{ek orodja, Taguchi metoda, metodologija odgovora povr{ine, optimizacija odgovora

Nickel-based alloy Inconel 718 is a kind of difficult-to-machine material, and the development of highspeed milling technology provides an effective machining method for the Inconel 718 parts. As the machining parameters play a crucial role in the high-speed milling of Inconel 718 parts, a lot of researches on the optimization of machining parameters have been conducted, and the optimum machining parameters under different test conditions have been obtained according to the experiments of flank milling or slot milling of Inconel 718. However, the machining parameter optimization in high-speed milling of Inconel 718 curved surface is seldom involved. The variation of the geometric features of the curved surface results in the sharp fluctuation of the cutting force as well as the vibration of the machine tool, which not only makes a severe impact on the surface machining quality and the tool life but also greatly affects the efficiency of the highspeed milling. In the machining process of the Inconel 718 parts with curved surface, the change of cutting force in highspeed milling should be smooth as far as possible. In this study, the experimental study is carried out on machining parameter optimization in high-speed milling of Inconel 718 curved surface based on the cutting force. The relationship between the cutting force and the spindle speed is analyzed, and in particular, the machining parameter optimization is investigated. The experiment results indicate that the cutting force relates to the geometric feature of curved surface, the cutting force is relatively smaller and the change of cutting force is smoother when the spindle speed changes from 4,000 to 4,500 rpm, the effect of the feed per tooth on the cutting force is little, and the cutting depth should be small to lessen the fluctuation of the cutting force. The research results can be considered to improve the machining quality of Inconel 718 parts with curved surface and will enrich the processing and manufacturing theory for the Inconel 718 parts.
