Title:
GEAR GRINDING MACHINE AND GEAR GRINDING METHOD
Document Type and Number:
WIPO Patent Application WO/2012/011392
Kind Code:
A1
Abstract:
The actual axial center position of a helical gear (10) relative to the axial center position of a rotary table (112) is calculated on the basis of input gear dimensions and information from a touch probe (120) (S1 to S3). Correction values for the positions and motions of the rotary table (112) and a grindstone (118) are calculated on the basis of the actual axial center position of the helical gear (10) (S8). Operation values for the rotary table (112), a column (113), a saddle (114), and a grindstone head (116) are calculated by adding the correction values to reference values for the positions and motions of the rotary table (112) and the grindstone (118) (S9). Motors (112M to 114M, 116M) are controlled in such a way that operation is carried out at the operation values to thereby carry out form grinding (S10).
