Optimal Controller for a 5-axis Machine Tool

“Optimal Controller for a 5-axis Machine Tool” aims to demonstrate how to build powerful and robust robotics applications in a simple way with Open CASCADE components.

this application capable of calculating the joint coordinates of a 5-axis milling machine was designed using the following three algorithms:

  • The inverse kinematic model of the machine,
  • A “Resolve Motion Rate” using the 6×5 Jacobian matrix of the machine,
  • A “Resolve Motion Rate” using the 3×5 Jacobian matrix of the machine and an optimization criterion that minimizes the machine displacements by allowing a slight error of the tool orientation around the normal of the surface to be milled.
