行−う必＊−ｆｉある。Conventional gear cutting machines (hobbing machines, gear shapers, etc.) suffer from change of cutter, workpiece change, deflection and relief due to the force of each part of the machine, and aging of the machine lip due to heat (about a few hours to a day). ), etc., it is necessary for the operator to measure the depth of cut Im (key 11).
この切込量の調整は今まで次のようにして行なりイいる
。Until now, this adjustment of the depth of cut has been carried out as follows.

First, measure the thickness of the gear tooth again using the manual, and calculate the second depth of cut from the measured value of □So□.
After that, either set the fixed size microphone 4 meters to the calculated depth of cut, or perform double gear cutting until the scale of the radial cutting device reaches the calculated depth of cut. .

切機械の歯厚゛自動補正方法に存する。The gist of the present invention for achieving this purpose is to automatically measure the tooth thickness of a gear section that is first mounted on a workpiece mounting base of a gear cutting machine and processed into a round plate workpiece, and to obtain the measured value. The depth of cut is determined by adding the escape amount due to elastic deformation during cutting and the amount of deformation over time due to heat, and this is stored. When machining the second and subsequent workpieces, the stored depth of cut is used. The invention relates to a method for automatically correcting the tooth thickness of a gear cutting machine, which adjusts the distance between a workpiece mounting base and a gear cutter based on the following.

。As described above in detail based on one embodiment, according to the automatic tooth thickness correction method for a gear cutting machine according to the present invention, there is no need for human labor for measurement. The process from setting to finishing of the workpiece can be automated (unmanned operation), and since the depth of cut is automatically calculated taking into account the effects of elastic deformation and thermal expansion, highly accurate gear cutting is possible. Further, since the measurement is performed immediately after the first gear cutting and the second gear cutting is performed, time can be shortened. Furthermore, it is possible to memorize the correction amount (Learning 1 function) and to create the second and subsequent workpieces in one gear cutting process, which also reduces work time. In addition, if you memorize the diameters of various tools, you can save the trouble of correcting the tool diameters when sizing.
