Kinematic accuracy of CNC gear shaper has great influence on the machining precision of gear work piece. The kinematic accuracy of CNC gear shaper is determined by coupling effects of mechanical system, control system and driving components of the gear shaper. In order to improve the kinematic accuracy of a large and heavy duty CNC gear shaper, a coupled electromechanical model of the gear shaper...
The finite element model of upper beam is established. Using deformation and quality as structural performance evaluation indicator, the key parameters that affect upper beam's structure performance are screened out. Obtained sequence of parameters that affects the structure properties of upper beam is as follows: upper and lower plate thickness, upper beam height, thickness of middle cross-plate,...
In order to make the design plan better reflecting the user requirement, and change the design manner from experience-driven to performance-driven design of the hydraulic press, a method of calculating the correlation between the user requirement and hydraulic press performance is proposed;Map between them is established by use of rough set theory. The result shows that this method can reflect the...
