SUMMARY:Exact 3D Path Generation via 3D Cam-Linkage Mechanisms
DESCRIPTION:Technical Papers\n\nExact 3D Path Generation via 3D Cam-Linkag
 e Mechanisms\n\nCheng, Song, Lu, Chew, Liu\n\nExact 3D path generation is 
 a fundamental problem of designing a mechanism to make a point exactly mov
 e along a prescribed 3D path, driven by a single actuator. Existing mechan
 isms are insufficient to address this problem. Planar linkages and their c
 ombinations with gears and/or plate cams can only generate 2D paths while 
 1-DOF spatial linkages can only generate 3D paths with rather simple shape
 s. In this paper, we present a new 3D cam-linkage mechanism, consisting of
  two 3D cams and five links, for exactly generating a continuous 3D path. 
 To design a 3D cam-linkage mechanism, we first model a 3-DOF 5-bar spatial
  linkage to exactly generate a prescribed 3D path and then reduce the spat
 ial linkage’s DOFs from 3 to 1 by composing the linkage with two 3D cam-fo
 llower mechanisms. Our computational approach optimizes the 3D cam-linkage
  mechanism’s topology and geometry to minimize the mechanism’s total weigh
 t while ensuring smooth, collision-free, and singularity-free motion. We s
 how that our 3D cam-linkage mechanism is able to exactly generate a contin
 uous 3D path with arbitrary shape and a finite number of C0 points, evalua
 te the mechanism’s kinematic performance with 3D printed prototypes, and d
 emonstrate that the mechanism can be generalized for exact 3D motion gener
 ation.\n\nRegistration Category: FULL ACCESS, ON-DEMAND ACCESS\n\nLanguage
