Two non-contact displacement meters are installed at intervals that can measure the distance to the workpiece surface, and the orientation change between the tool slide and the workpiece rotation axis is detected based on the output signals of both displacement meters. This method is characterized by displacing the tool rest while eliminating the influence of the above, and controlling the depth of cut so as to perform cutting along a preset target shape.

は工具8が取付けられている。FIG. 1 shows the configuration of a cutting device in which the processing method of the present invention is applied to face cutting using a lathe. In this cutting device, a workpiece 3 is attached to the main shaft 1 of the lathe via a workpiece fixture 2. The workpiece 3 is rotated around the workpiece rotation axis 3a by the main shaft l. On the other hand, the tool slide 5 that moves along the guide 4 includes a small displacement tool stand 6 that can minutely control the amount of cut, and a non-contact displacement tool that can measure the distance in the cutting direction between the tool slide 5 and the workpiece surface 3b. A total of 7 tools are attached, and a tool 8 is attached to the tip of the minute displacement tool stand 6.

15によってその位置を検出することができる。The minute displacement tool stand 6 can have a structure as shown in FIG. 2, for example. The micro-displacement tool stand 6 shown in the same figure connects four rigid side members 11 at thin elastic bending parts 12 located at the four corners, and is made of an elastic metal material to allow elastic deformation. The tool 8 is fixed on the guide member 10, and a piezoelectric element 14 is provided between the convex portions 13.13 from the upper and lower side members 11.11 to move the tool in parallel. A non-contact displacement meter 15 is installed at one end of 8 to detect the displacement of the tool.
are set up opposite. Therefore, by changing the distance between the protrusions 13.13 by controlling the piezoelectric element 14, the position of the tool 8 in the cutting direction can be controlled, and the position can be detected by the displacement meter 15. .

ことによって行われる。この際、非接触変位計7は既に
切削の終った被削面3bに対向するように位置させ、切
削中に工作物既被削面との間の距離を常に計測させる。In the lathe described above, cutting with the tool 8 is performed by moving the tool slide 5 in the X direction along the guide 4 while the main shaft is rotating. At this time, the non-contact displacement meter 7 is positioned so as to face the cut surface 3b that has already been cut, and constantly measures the distance between it and the already cut surface of the workpiece during cutting.

装置18においては次のような演算が行われる。A control device 18 connected to the minute displacement tool stand 6 and the non-contact displacement meter 7 generates a depth of cut control signal for cutting along a preset target shape based on the output signal of the non-contact displacement meter 7. The tool stand 6 is generated by the control signal.
The control device 18 controls the amount of cut by displacing the .
いま、時刻Eにおける変位出力を5(t)、工具台6へ

、へとった座標である。Now, let the displacement output at time E be 5(t), the control input to the tool rest 6, that is, the depth of cut of the tool rest 6, be u (t), and the shape of the cut workpiece 3 be z (X) Expressed as. Here, X is a coordinate taken from the center in the radial direction, and 2 is a coordinate taken in the thickness direction.

。そして、工具スライド5は運動中に工作物回転軸3a
に対して傾き角の変化が生じないものと仮定すると、以
下の関係が成り立つ。It is assumed that during cutting, the tool slide 5 is moving in the X direction at a constant speed V, and the tool is at the position x=vt at time. During the movement, the tool slide 5 rotates around the workpiece rotation axis 3a.
Assuming that there is no change in the inclination angle, the following relationship holds true.

-Zo(x)・Fist・(2) If Z (X)=20(+), the tool 8 and workpiece 3 due to motion errors of the spindle 1 and tool slide 5, deformation of the machine structure, etc. The shape of the workpiece can be made to match the desired value regardless of control errors in the relative positional relationship between the two.

作物3形状が確定できる。However, during cutting, the shape Z (X) of the workpiece 3 needs to be known in advance in the range -Vτ≦X≦0. However, in this short section, even if cutting is performed using the normal method without the above-mentioned control, the influence of disturbance on the resulting surface shape is considered to be sufficiently small, so the cut surface can be used as a reference with a known shape. It can also be a face. In this case, by using the reference surface as the gg primary reference surface and cutting according to the control law of equation (2), the 0
The shape of the workpiece 3 obtained in the interval ≦X≦Vτ can be determined. By using the surface thus obtained as a secondary reference surface and performing similar control, the shape of the workpiece 3 can be determined even in the primary section Vτ≦X≦2vτ.

The shape Z (X) of the workpiece 3 can be maintained over a wide area without being affected by undesired relative positional errors between the tool 8 and the workpiece 3 due to expansion and contraction of the spindle l, deformation of the machine structure, meandering of the tool slide 5, etc. can be made to match the desired value 20(X).

形を与えている。Figure 4 shows that during face cutting of aluminum alloy, an external force is applied to the tool slide 5 in the direction of separating it from the workpiece 3, deforming the machine structure, and as a result, there is a gap between the bundled tool slide and the workpiece. This figure shows the effect of a distance change on the shape of the cut surface of the workpiece 3, and therefore, control based on the present invention is not performed. In this experiment, as shown in the figure, the machine structure was deformed to the extent that convex portions corresponding to 0.2 m, 0.5 m, and 1.0 m were formed on the machined surface. giving.

具スライド5と工作物3の距離変化とを区別することが
できない。The tool slide 5 in the device example shown in FIGS. 1 and 2 described above may tilt with respect to the workpiece rotation axis 3a during movement. Furthermore, as the spindle 1 rotates, there is a change in the orientation of the rotation axis (angular motion), which also causes a change in the orientation between the tool slide 5 and the workpiece rotation axis 3a. In the configuration shown in FIG. 1, it is not possible to distinguish between this change in orientation and a change in the distance between the tool slide 5 and the workpiece 3.
このような工具スライド5と工作物回転軸3aとの間の

行うようにしているが、その他の構成は第1図の装置例
の場合と実質的に同一である。When the influence of such a change in orientation between the tool slide 5 and the workpiece rotation axis 3a is large, it is effective to use a tool slide 25 as shown in FIG. 3. The tool slide 25 shown in the figure has two non-contact displacement meters 27a and 2 that measure the distance between the cut surface of the workpiece 23 and the tool slide 25.
7b from the tool 28 in two different positions d I + d
2, and based on the outputs of these displacement meters 27a and 27b, the distance between the tool slide 5 and the workpiece rotation axis 3a is measured while removing the influence of changes in orientation. However, the other configurations are substantially the same as the example of the apparatus shown in FIG.

+ z (り −z (x−d2) −d2θが成り立
ち、これより、
−51(t) + 52(t) )
を得る。If the outputs of the displacement meters 27a and 27b in the example of the device shown in FIG. 3 are 51(t) and 52(t), and the tilt angle of the tool slide 25 is θ, then 51(t) = u (t) + z (x) −z
(x-d+) -d+θ52(t) = u (t)
+ z (ri −z (x−d2) −d2θ holds, and from this, −51(t) + 52(t) ) is obtained.
ここで、

If we set o(x), then Z (K) −Zo(x),
As in the case of the embodiment shown in FIG. 1, a cut surface having a desired shape can be obtained.
