To improve the stiffness and to realize lightweight of working table direct-drive machine tool, similarity between wing structure is analyzed. The structural characteristics membrane veins are used as design guidelines for bionic ribbed plate table. A new finally obtained. static properties common table, leaf compared with finite element simulation. 3D printer fabricate an equally scaled-down model reliability simulation results verified through load experiments. Deformation morphology stiffness-strengthening mechanisms three types tables studied methods combining compression experiments FEM analysis. research show that has most decrease in deformation among similar masses. Compared maximum reduced by 25.6% average 21.9%. compressive strength significantly higher than tables. integrated transverse partition imitation stiffener vein can torsional stiffener. mainly compression, S-type curves two half-waves symmetrically centered on created. layout rib based features effectively tool. a uniform distribution guarantee high machining accuracy

This work proposes a methodology to determine the height difference of guideways machine tools where two are not placed on same horizontal plane. Firstly, rigid-flexible coupling system consisting moving rigid mass and an elastic overhanging beam is presented as equivalent mechanical model column spindle box. Then, relationship between deviation reference point or box's stroke modeled. Next, natural frequency mode shape function beam, response functions system, derived. The results indicate that there always exists optimal minimizing relative deflection over part, value depends loads in directions part. Similarly, also choice maximizing first-order resonant system; however, solutions for both static dynamic cases same. provides beneficial instruction choosing with bed
