We suggested a novel method to maintain a machined surface quality of a curved surface shape by synchronous motion between two linear axes and a rotary axis with the five-axis machining center. It was demonstrated that the proposed method made it feasible to prevent a machined error due to the quadrant glitch caused by friction of the ball screw and linear guide of feed drive system b... https://www.infonoticiasgandia.com/product-category/chutoh-knives/
