Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、数値制御装置に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a numerical control device.
従来、数値制御装置（以下NCという）の発す
る軸指令と、工作機械の各軸とは一対一の対応が
固定されていた。
Conventionally, there was a fixed one-to-one correspondence between axis commands issued by a numerical control device (hereinafter referred to as NC) and each axis of a machine tool.
例えば、第１図に示すように、NC１の軸指令
gx，gy，gzが、工作機械の機械的移動軸G1，G2，
G3にそれぞれ対応する例を考える。このとき、
第２図に示すように、G1−G2平明で円軌跡C1-2
を描かせる場合、軸指令gxとgyは、いわゆる円弧
補間を行う必要がある。
For example, as shown in Figure 1, the axis command of NC1
g x , g y , g z are the machine tool's mechanical movement axes G 1 , G 2 ,
Consider examples corresponding to G 3 . At this time,
As shown in Figure 2, G 1 −G 2 plain and circular locus C 1-2
When drawing the axis commands g x and g y , it is necessary to perform so-called circular interpolation.
同様にG2−G3平面で円軌跡C2-3を描かせる場
合、軸指令gyとgzは、円弧補間を行う必要があ
る。ところが、軸指令gx，gy，gzと軸G1，G2，
G3が一対一にて対応しているので、前記gx−gy
円弧補間と、gy−gz円弧補間とは、実質的に同一
処理であるにもかかわらず、それぞれ別個の軸指
令プログラムが必要であるという欠点があつた。
特にgx−gy円弧補間後にgy−gz円弧補間を行わせ
る場合などは、別個の軸指令プログラムが必要で
あるとうことは不便このうえないものとなる。 Similarly, when drawing a circular locus C 2-3 on the G 2 −G 3 plane, the axis commands g y and g z need to be circularly interpolated. However, the axis commands g x , g y , g z and the axes G 1 , G 2 ,
Since G 3 has a one-to-one correspondence, the above g x −g y
Although circular interpolation and g y - g z circular interpolation are substantially the same process, they each have the disadvantage of requiring separate axis command programs.
In particular, when performing g y - g z circular interpolation after g x - g y circular interpolation, the need for a separate axis command program is extremely inconvenient.
さらに、第１図に示したものに、軸を追加する
場合も下記の欠点があつた。 Furthermore, when an axis is added to what is shown in FIG. 1, the following drawbacks occur.
例えば、第３図に示すように、インデツクス軸
G4，G5を追加する場合、基本NC部２の他にこれ
らの軸を制御する追加NC部３を追加する必要が
ある。しかも、基本NC部２と追加NC部３との
間に相互拘束（インタロツク）４が必要となり、
回路が複雑化するうえ、基本軸と追加軸との間で
は、従来のプログラムが通用しなくなるため、新
たなプログラムが必要となるという欠点がある。 For example, as shown in Figure 3, the index axis
When adding G 4 and G 5 , it is necessary to add an additional NC section 3 to control these axes in addition to the basic NC section 2. Moreover, a mutual restraint (interlock) 4 is required between the basic NC section 2 and the additional NC section 3.
This has the disadvantage that the circuit becomes complicated, and a new program is required because the conventional program is no longer applicable between the basic axis and the additional axis.
一方、実公昭56−321号公報には、指令パルス
をどの軸に与えるか選択回路を有するものが開示
されているが、時間の経過にしたがつてどの軸に
与えるか選択を変えていくことはできない。 On the other hand, Japanese Utility Model Publication No. 56-321 discloses a device having a circuit for selecting which axis the command pulse is applied to, but the selection of which axis to apply the command pulse to is changed over time. I can't.
そこで、本発明は、指令パルスをどの軸に与え

その選択を変えていくことができる装置を提供す
ることを目的とする。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a device that can select which axis to apply a command pulse to, and can change the selection as time passes.

A specific example will be described below with reference to FIG. As an example, the basic NC section 2 is assumed to be capable of simultaneous three-axis control. The axis command distributor 5 is, for example,
As shown by the broken line, the axis commands g x can be freely distributed to the axis G2, the axis commands g y to the axis G3, the axis commands g z to the axis G5, etc., based on the axis designation command 6. . FIG. 5 shows a specific circuit example in which the axis command distributor 5 is constituted by a latch register 7, multiplexers 8-a, 8-b, 8-c, and OR elements 9-13. Here, the simultaneously controlled axis commands g x ,
Consider the case where a spiral motion as shown in FIG. 6 is performed using g y and g z . For example, the spatial axis in Figure 6
When it is desired to assign G x to axis G2, spatial axis G y to axis G3, and spatial axis G z to axis G5, the axis command distributor 5 receives the axis designation command 6 to that effect and sends the axis commands g x , g y , g z
is given to G2, G3, and G5. At this time, the axis command
g x and g y are commands to draw a circle on the G2-G3 plane, and axis command g z is a command to move in the direction perpendicular to the circle.
もし、Gx，Gy，GzをＧ１，Ｇ２，Ｇ４に担当
させたいのであれば、その旨の軸指定指令６を発
すれば良い。 If you want G1, G2, and G4 to be in charge of G x , G y , and G z , you can issue an axis designation command 6 to that effect.
このように、NC部４は、常に同時制御できる
gx、gy、gzの３軸指令の動作プログラムを用意し

て容易に実現できる。 In this way, the NC section 4 can always be controlled simultaneously.
By preparing an operation program for the three axis commands of g x , g y , and g z , the operation of all axes can be controlled simply by changing the distribution of axis commands. In addition, complex mechanical operations can be realized extremely easily by programming in advance to sequentially change the axis designations according to the operation sequence.
