ABSTRACT
Assuming that gear cutting parameters (the motion parameters of the machine) Φ j (j = 1, 2, .., m is the number for machine tool motion parameters, including cutter diameter r, tooth profile angle α, installation angle , horizontal displacement X, vertical displacement B, processing displacement E and roll cutting ratio R, etc) are known, after a series of coordinate transformation and the derivation process[6], we get the theoretical tooth surface H of measurement coordinate system and the unit normal vector n, compensate the probe radius H, and get the theory trajectory of measurement header heart He.
