Embodiment Construction
[0103] The specific embodiment of the present invention will be described below in conjunction with the experimental measurement method and the accompanying drawings.
[0104] attached figure 1 The QC20-W ballbar measuring equipment involved in this experiment.
[0105] In step 1, the position-independent geometric error of the dual rotation axes of the cradle five-axis machine tool is redefined according to the principle of unit dual quaternion transformation, and based on this, the ideal and actual kinematic model of the five-axis machine tool is established, including steps:
[0106] Step 1.1, based on the unit dual quaternion, give the exponential representation of its screw motion:
[0107]
[0108] where the dual angle and the dual vector Respectively represent the motion process of the screw motion and the pose of the helical axis around, θ represents the rotation angle around the helical axis, d represents the displacement distance along the helical axis, n re...
