TL;DR: In this article, an experimental study was conducted on the dry drilling of Ti-6Al-4V. The objective of this study was to establish the correlations between drilling parameters such as feed rate and spindle speed, and quality of machined surface which is evaluated in terms of drill hole diameter deviation, exit burr height and surface roughness.

TL;DR: In this article, a method to design hydroxyapatite scaffolds based on gradient porosity was proposed, and after a tailor-made ceramic suspension was cured by stereolithography (SLA), a minimal pore with a diameter size of 500μm can be fabricated, and it has a high dimension precision up to about 60μm.

TL;DR: An insight into the design, analysis, and in vitro experiment of a bone tissue engineering scaffold is provided and the result shows that the inlet velocity 0.0075 m/s is suitable for cell proliferation in the scaffold.

TL;DR: In this paper, the effect of important drilling parameters such as spindle speed and feed rate on effectiveness of process and quality of holes during drilling of difficult-to-machine Al/SiC metal matrix composite using diamond-coated cemented carbide tool was investigated.

TL;DR: In this article, percentages of nickel as austenizer and chromium as ferritizer, in the molten metal pool of SS304L weldments are varied to analyze the effect on the produced delta ferrites morpho...
