えるために、次の工程を実施しなければならない。The cam, generally designated by 1, has an actuating surface 2. The working surface 2 is formed as an envelope of successive positions occupied by a plane rotating about the axis X-X. This envelope occupies a different angular position with respect to the axis X-X as it rotates. In FIG. 1, the mother surface is shown in two consecutive positions, namely planes (A) and (B). The plane (A) is arranged tangentially to the actuating surface 2 of the cam along the generatrix 7, while the plane (B) is arranged tangentially to the actuating surface 2 along the generatrix 8. In the case shown, bus 7
And 8 are inclined with respect to the axis X-X. However, the busbars 7, 8 can also be parallel to or intersect the axis XX, in which case the busbars 7, 8 must belong to the plane containing the axis XX. Would. The cam 1 is carried by a simple shaft 3 which has said axis XX as its axis. The right cylindrical grinding wheel, indicated generally by 4, has a flat front working surface 5 in the form of a circular ring. Grinding wheel 4 has axis Y
It can rotate around -Y. Axis Y-
Y intersects the axis X-X and X 1 in FIG. 1 and is perpendicular to the axis X-X. The plane (A) in FIG. 1 is also perpendicular to the plane YYX 1 X defined by the two axes XX and YY. The plane (A) intersects, along the dashed line 6, the plane defined by the two axes XX and YY. In FIG. 1, the broken line 6 is parallel to the axis XX. As a result, when the grinding wheel 4 is fed toward the cam 1, the machined surface 5 of the grinding wheel engages the working surface 2 of the cam 1 along the generatrix 7. In the position shown in FIG. 2, the cam 1 has the plane (B) on the axes X-X and Y-.
It has been rotated so that it is oriented perpendicular to the Y plane YYX 1 X. This plane (B) has two axes X-X and Y-Y.
Intersects the plane YYX 1 X defined by The busbar 9 is not parallel to the cam axis XX,
It intersects the axis X-X to form an angle (K). As a result, the busbar 9 is not parallel to the surface 5 of the grinding wheel,
Form an angle (K) with. Referring to FIG. 3,
The broken line shows the cam 1 in the same position as in FIG. 2, while the axis is the plane YY defined by the axes XX and YY.
X 1 X Cam axis X- around swing axis Z-Z perpendicular to X
Shown is the cam 1 in a position obtained by rotating X by an angle K, the busbar 9 formed by the intersection of the plane (B) with the plane formed by the axes XX and YY being ground. It is arranged so as to be parallel to the surface 5 of the grinding wheel. At this position, when the grinding wheel 4 is advanced in parallel with its axis Y-Y, the processed surface 5 of the grinding wheel 4 engages with the cam surface 2 along the generatrix 8. As a result, the following steps must be performed in order to change from the processing position shown in FIG. 1 to the processing position shown in FIG.
(i)第２図においてシャフト３を角度（Ｆ）だけ回転す
る。(i) In FIG. 2, the shaft 3 is rotated by an angle (F).
(ii)シャフト３の軸線Ｘ−Ｘを第３図に示したように角
度（Ｋ）だけ揺動し、 (iii)研削用砥石４をその軸線Ｙ−Ｙに平行に移動す
る。(ii) The axis X-X of the shaft 3 is swung by an angle (K) as shown in FIG. 3, and (iii) the grinding wheel 4 is moved parallel to the axis Y-Y.
これらの三工程が同時に行われる。もしも研削工程によ

あれば、角度（Ｆ）の値、それに応じたカム軸線Ｘ−Ｘ

とができる。These three steps are performed simultaneously. If the shape of the cam operating surface 2 that needs to be formed by the grinding process is known, the value of the angle (F) and the corresponding cam axis XX
It is possible to calculate all the values of the rocking angle (K) and the corresponding amount of movement of the grinding wheel 4 along the axis Y-Y.
それ故に、研削用砥石の移動量および揺動角度（Ｋ）の
値はシャフト３の回転量即ち角度（Ｆ）の値によって決

砥石４がその加工面５によりカム１所要の作動面２を形
成する。Therefore, the amount of movement of the grinding wheel and the value of the swing angle (K) can be determined by the amount of rotation of the shaft 3, that is, the value of the angle (F). As a result, the shaft 3 is slowly rotated about its axis X-X to oscillate the shaft 3 by an amount equal to a continuously changing angle (K) while the shaft 3 rotates about its axis. When the grinding wheel 4 is moved in parallel with the axis of the grinding wheel 4 accordingly, the grinding wheel 4 rotating at a high speed around the axis Y-Y of the grinding wheel causes the working surface 5 to move the working surface required by the cam 1. Form 2.
