TL;DR: This paper applies the theory of Geometric Algebra to the kinematic modeling of 6R robot manipulators simply and generate closed-form kinematics equations, reformulate the problem as a generalized eigenvalue problem with symbolic elimination technique, and then yield 16 solutions.

TL;DR: In this article, the authors proposed a criterion to determine initial condition based on the calibration of surface residual stress, and computed the residual stress in different depth of machined surface can be computed using the proposed analytical residual stress model, and the computed results are consistent with experiment results.

TL;DR: In this article, a new analytical chatter model is presented for the simulation and analysis of chatter vibration in orthogonal cutting processes, which can determine the dynamic cutting forces theoretically with the equivalent cutting parameters from the material properties, tool geometry and cutting conditions.
