However, the latter method has the disadvantage that it is difficult to maintain accuracy due to wear of the guide and gear pair, and that it is impossible to machine gears with broken shafts. Therefore, the tool and workpiece gear are each N.

When the distance between the centers of the gears increases to a distance where their respective pitch circles overlap at one point, the teeth contact at two points. Gear carving tool applied to the processing machine according to the present invention (1)
Since this is a workpiece gear and the tooth thickness changes further as the tool wears, there is a problem that the initial phase of meshing must be controlled by shifting it as shown in FIG. 5. On the other hand, in actual machining, one tooth surface on the opposite side must also be enameled, so the phase must be shifted by the same amount in the completely opposite direction during machining. of·)
Furthermore, a mechanism is required to control the rotation angles of the tool (1) and the tool (1) and to bring the tooth surfaces of the two into contact with each other with a constant pressure.

a) ), move one slide to bring the axis (1゛) (a) closer to the extent that the pitch circles overlap (Figure 3 (b))
. Here, in FIG. 1, one side of the control loop runs from the first servo motor position control circuit (7) to the first speed control circuit (5).
The second servo motor position control circuit (8) is controlled by switch α.
) is separated, and the rotational speed signal commanded from the speed command circuit α4 is directly input to the second speed control circuit (6) to form a speed control loop. At this time, the second speed control circuit (6
)'s Denki P 几る. Of course, at this time there is no output from the pulse distributor (9) which is the position command distribution control section, and therefore the first servo motor (3) is in the servo lock state. The second servo motor (4) rotates to feed the tool (1) and workpiece gear (2).
One tooth surface of the is pressed to a constant torque, and it balances and stops. Here, the rotation angle of the second servo motor (4) is determined by the encoder (6).
) Since the generated pulse train is input to the second position control circuit (8) and counted, the current rotation angle between the tool axis (lo) and the workpiece gear axis is always read. Therefore, the command is offset by the initializer υ so that the phase difference between the tool axis (11) and the workpiece gear axis in this state becomes zero.
After that, the switch α and αG are switched to connect the second speed control circuit section (6) and the second servo motor position control circuit (8) to create a position control loop, and to control the pre-programmed tool and workpiece. Position and speed commands corresponding to the number of teeth are given from the pulse distributor (9) to rotate (FIG. 3(C)).
