Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with specific embodiments.
[0027] The blade parts are: the intake and exhaust edges of precision forged blades of aero-engines, and the grinding equipment is: a seven-axis linkage CNC abrasive belt grinder, which is connected to the adjustment module, and the blade type is set in the adjustment module. A method for adjusting the position and orientation of a tool shaft for grinding a part, comprising the following steps:
[0028] Step 1, establish the knife contact coordinate system ζ (L) and workpiece coordinate system ζ (w) , ξ (L) =[P c ; e 1 (L) ,e 2 (L) ,e 3 (L) ], P c is the contact point between the tool and the tool touch track r(t) on the surface to be processed at the current moment, e 1 (L) is the tool touch trajectory at the cutting point P c The unit tangent vector at, e 3 (L) For the processed surface r(u, v) at the cutting point P c The unit normal vector at e 2 (L)...
