Notes concerning different machine kinematics

When no transformations are active and the working plane is not tilted, the linear machine axes move in parallel with the basic coordinate system B-CS. In this process, machines behave almost identically, regardless of the kinematics.

Basic coordinate system B-CS

When tilting the working plane, the control moves the machine axes according to the kinematics.

Please observe the aspects below regarding the machine kinematics:

  • Machine with table rotary axes
  • With this kinematic model, the table rotary axes execute the tilting movement and the position of the workpiece in the work envelope changes. The linear machine axes move in the tilted working plane coordinate system WPL-CS just as they do in the non-tilted B-CS.

  • Working plane coordinate system WPL-CS

  • Machine with head rotary axes
  • With this kinematic model, the head rotary axes execute the tilting movement and the position of the workpiece in the work envelope remains the same. In the tilted WPL-CS, at least two linear machine axes no longer move in parallel with the non-tilted B-CS, depending on the rotary angle.
