“…In addition, an analysis of variance (ANOVA) determines the statistically significant process parameters. After the analyses (S/N and ANOVA) have been conducted, a confirmation experiment is performed to verify the optimal process parameters acquired from the parameter design (Taguchi et al 1989;Nalbant et al 2007;Gologlu and Sakarya 2008). Some researchers have reported on the effect of cutting speed and feed rate on surface roughness in wood and wood-based materials by milling and drilling of a CNC router (Davim et al 2009;Sutcu and Karagoz 2012;Sutcu 2013;Valarmathi et al 2013).…”

In this paper, the optimization of computer numerical control (CNC) machining parameters were conducted using the Taguchi design method on the surface quality of massive wooden edge glued panels (EGP) made of European larch (Larix decidua Mill). Three machining parameters and their effects on surface roughness were evaluated. These parameters included tool clearance strategy, spindle speed, and feed rate. An analysis of variance (ANOVA) was performed to identify the significant factors affecting the surface roughness (Ra and Rz). Optimum machining parameter combinations were acquired by conducting an analysis of the signal-to-noise (S/N) ratio. Optimal cutting performance for the Ra and Rz was obtained for the cutter at a tool clearance strategy of an offset 16000 rpm spindle speed and 1000 mm/min feed rate. The surface roughness, both the Ra and Rz, increased with increasing feed rate. Optimal cutting performance for Ra and Rz was obtained for a tool clearance strategy of an offset 16000 rpm spindle speed, and 1000 mm/min feed rate cutting settings. Based on the confirmation tests, Ra decreased 2.2 times and Rz 1.8 times compared to the starting cutting parameters.

Original scientific paper In this study, the aging period (20, 30, 40 and 50 days), the edge banding thickness (0,4; 0,8;1,0 and 2,0 mm) and the type of force used (bending strength-MOR and tensile strength-MOE) were the parameters selected for analysis of the effects on the mechanical properties of melamine coated particle board. To do this, Taguchi's methodology for the design of experiments was used to optimize the process parameters. Trials are conducted using an L16 orthogonal array with 16 combinations of test variables to assess the influence of various factors. Analysis of variance was also employed to investigate which design parameters significantly affect the mechanical properties of melamine coated particle board. The statistical analysis showed that the type of force used was the most significant factor affecting the response. The simulated and experimental results also showed good agreement with each other.

U tu svrhu, Taguchijevo oblikovanje metodologije pokusa provedeno je za optimizaciju procesnih parametara. Pokusi su provedeni po ortogonalnom polju L16 sa 16 kombinacija ispitnih varijabli za procjenu utjecaja različitih čimbenika. Analiza varijance također je bila uključena za istraživanje koji parametri konstrukcije značajno utječu na mehanička svojstva melaminom obložene iverice. Statistička je analiza pokazala da vrsta ostvarivanja sile krajnje promjenjivo djeluje na odziv. Simulirani i eksperimentalni rezultati također pokazuju dobro slaganje jednih s drugima.

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
