制御される旋盤（多軸数値制御旋盤）の加工制御方法に
関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a processing control method for a numerically controlled lathe (multi-spindle numerically controlled lathe) having a plurality of spindles and moving the spindle.
多ｌ１ｑｂ数値制御旋盤による旋削加圧において、ワー
クが長尺、細物の場合、ワークの先端か振れて、加重精
度か悪くなる。When turning and applying pressure using a numerically controlled lathe, if the workpiece is long or thin, the tip of the workpiece will swing and the loading accuracy will deteriorate.

移動軸の動作指令とすることにより、両ｌ−輔移動軸の
動作を同期させるものてある。(One step to solving the problem) The processing control method of the multi-axis numerically controlled lathe invented by Wooden supports both ends of the workpiece with two spindles, and applies the same amount of force to the drive motor of each of these 1-IIIll spindle movement axes. At the time of deceleration, P() is provided, and the operation command for one main shaft moving axis is used as the operating command for the other main shaft moving axis, thereby synchronizing the operations of both l-axis moving axes.
ワークの両端を２つの主軸で支持し、両主軸移動軸を同
期運転させるので、ワークの振れを簡単なプログラムで
防止することができる。Both ends of the workpiece are supported by two main shafts, and both main shaft movement axes are operated synchronously, so workpiece wobbling can be prevented with a simple program.
次に、本発明の実施例について図面を参照して説明する
。Next, embodiments of the present invention will be described with reference to the drawings.

移動する。The workpiece 3 is supported at both ends by the main spindle 1 and the back main spindle 2,
The main spindle movement axis (Z-axis) and the back main spindle movement axis (B-axis) allow
It moves in the direction of the arrow together with the main shaft 1 and the back main shaft 2. On the other hand, the tool rest 4 moves only in the direction of the arrow (X).

The /A converter 24 and the axis CPU 25 constitute a servo mechanism for the motor 21. The FGCPU 18 to which commands from the main CPU 19 are set includes Z-axis registers 16,
In addition to the B-axis register 26, decode the command from the main CPU 19, and if it is a synchronous feed command (0167), copy the command given to the Z-axis as is and set it in the B-axis register 26 (of course A decoder 17 (software) for setting the Z axis and also setting the register 16 is provided.

Specifically, the position of the front block on the Z axis is 250. If you are at the point Z 50. The movement amount of →z i o o is calculated internally and treated as the movement of BIIIiIII.

の完全同期を実現する。Then, the decoder 17 determines from the code rG167 that the B-axis needs to perform exactly the same movement as the Z-axis movement, and based on this Z-axis command, moves the B-axis to the amount that the Z-axis moves per unit time. Set to . That is, by copying the Z-axis movement at the amount of movement per unit time, complete synchronization between the B-axis and the X-axis is achieved.
なお、主軸１と背面主軸２も理論上は同期させる必要が

）。The main spindle 1 and the back main spindle 2 should also be synchronized in theory, but in reality they are not synchronized, and the back main spindle 2 is dragged (followed) by the main spindle 1 because its power is weaker.

果がある。As explained above, the present invention supports both ends of the workpiece with the spindle and operates the spindle moving axes in perfect synchronization during machining, thereby reducing the run-out of the workpiece without the need for a special mechanism. This has the effect of preventing this and increasing machining accuracy.
