In this study, ANalysis Of VAriance (ANOVA) and Response Surface Methodology were applied to characterize and optimize laser milling of Carbon Fiber Reinforced Polymer (CFRP) plates. The process was performed by means of a 30W Q-switched Yb:YAG fiber laser, working at the fundamental wavelength of 1064 nm. The machined material was a CFRP plate, 4 mm in thickness, obtained by autoclave cure. According to Design of Experiments (DoE) methodology and previous experiences, a Central Composite Design (CCD) was developed and applied. The investigated parameters were the scan speed, the pulse frequency, the number of repetitions of the geometric pattern and the hatch distance. The suitable milling conditions were obtained from the response surface model. The model allows to set the process parameters to obtain the desired depth with an error <3% and a MRR higher than 1.9 × 10−3g/s. POLYM. ENG. SCI., 57:595–605, 2017

“…In such cases, according to the authors, an accurate pre-design is the keystone to maximize achievable experimental results, since it allows all available expertise to be systemized, by means of well-defined operative and analysis procedures, thus reducing efforts, costs and time for this kind of process characterizations [ 19 , 20 ].…”

A statistical approach for the characterization of Additive Manufacturing (AM) processes is presented in this paper. Design of Experiments (DOE) and ANalysis of VAriance (ANOVA), both based on Nested Effects Modeling (NEM) technique, are adopted to assess the effect of different laser exposure strategies on physical and mechanical properties of AlSi10Mg parts produced by Direct Metal Laser Sintering (DMLS). Due to the wide industrial interest in AM technologies in many different fields, it is extremely important to ensure high parts performances and productivity. For this aim, the present paper focuses on the evaluation of tensile properties of specimens built with different laser exposure strategies. Two optimal laser parameters settings, in terms of both process quality (part performances) and productivity (part build rate), are identified.

In the present study, fibre laser microdrilling of NIMONIC®263 sheet is investigated through an experimental testing campaign. Design of experiments (DOE) and analysis of variance (ANOVA) are applied with the aim to study the influence of the process parameters on the hole geometry and metallurgical properties. The results show that the laser allows drilling ~0.4-mm-thick NIMONIC®263 sheets with a trepanning speed up to 600 mm/min, obtaining good tolerance, low recast layer and absence of microcracks
