Abstract

PURPOSE:To perform efficiently multiaxis interpolation with a simple constitution by setting the longest axis data by calculation and inputting the longest axis data into each two-axis linear interpolation controller as a dummy axis, and then, performing linear interpolation of more than three axes. CONSTITUTION:To devices 11A, 11B, and 11C which perform interpolation of X-, Y-, and Z-axes, respectively, moving quantity data of each axis are inputted. Moreover, the data of P-axis which becomes a dummy axis are inputted into the devices 11A, 11B, and 11C. The longest one among the data of X-, Y-, and Z- axes is used as the P-axis data. The device 11A performs the linear interpolation of the X-axis data and the longest axis data and outputs the interpolation data of X-axis. In the same way, the devices 11B and 11C output the interpolation data of Y- and Z-axes, respectively. These interpolation data are interpolated with the longest axis and correspond to the moving quantity. The moving distance is based on the largest axis and in axes, whose moving distances are shorter than the largest axis, the moving speed is set so that the speed becomes slow.

に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-axis linear interpolation control method in a numerical control device, etc., and particularly relates to a multi-axis linear interpolation control method that performs linear interpolation on three or more axes using a plurality of two-axis linear interpolation devices. This invention relates to a linear interpolation control method.

の補間を行うものと三軸以上の補間を行うものがある。Conventionally, linear interpolation devices and circular interpolation devices have been used as interpolation devices. Among these, linear interpolation devices are designed to move along a straight line at an arbitrary angle, and there are two types of linear interpolation devices: those that perform two-axis interpolation, and those that perform three or more axes interpolation.

一般に、二軸の場合には比較的簡単に補間を行うことが

ログラムの作成が煩雑になるといつた問題を生じる。Generally, in the case of two axes, interpolation can be performed relatively easily, but when there are three or more axes, the control becomes complicated and the creation of a program becomes complicated.

本発明は、簡単な装置を用いて三軸以上の補間を行うこ
εを目的とするものである。An object of the present invention is to perform interpolation on three or more axes using a simple device.

い。When performing interpolation using several biaxial linear interpolators, simultaneous interpolation cannot be performed if each is used separately. In other words, do not perform X-Y axis interpolation and Y-Z axis interpolation separately (each interpolation must be performed according to the amount of movement of each of the X, Y, and Z axes. .

なうようにしている。In order to achieve the above object, in the multi-axis linear interpolation control method according to the present invention, one input of a plurality of two-axis interpolation control devices is used as data for each axis, and the other inputs are used as data for the longest axis. Interpolation is performed according to these two data.

それによって、多軸のデータに応じた補間を行うもので
ある。Thereby, interpolation is performed according to multi-axis data.

% Data of the Y-axis, Y-axis, and Z-axis movement amounts are input to the device 11B that performs Y-axis interpolation and the device engineer ICKf'i that performs Z-axis interpolation, respectively.

出力が疑似軸となるＰ軸のデータとなる。P-axis data, which is a pseudo axis, is still input to each of the devices 11A, IIB, and 11c. The data on the P axis, which is the pseudo axis, is the largest of the data on the Y, Y, and Z axes. Therefore, means is provided to select the longest axis data by calculating the Y-axis, Y-axis, and Z-axis data, and the output thereof becomes the P-axis data, which is the pseudo axis.

てはＺ軸のそれぞれの補間データを出力する。The biaxial linear interpolation device 11A performs linear interpolation between the Y-axis data and the longest axis data, and outputs Y-axis interpolated data. Similarly, the device 11B outputs interpolated data for the Y axis, and the device 11C outputs interpolated data for the Z axis.

うに設定される。These Y-axis, Y-axis, and Z-axis interpolation data are interpolated between the longest axis and become data corresponding to the amount of movement thereof. The axis with the maximum movement distance is used as a reference, and the movement speed is set to be slower for axes with shorter movement distances.
