Study on U-axis mechanism design and parameter calculation

A U-axis mechanism based on 2K-H (C) type planetary differential was designed to process turning contours in large/heavy workpieces or slender shafts with equal-diameter or variable-diameter sections. The working principle of the mechanism was analyzed by taking facing head as an example, providing a theoretical foundation for the U-axis feeding parameter design. Deformation systems were also proposed to meet the working requirements of different situations.
