Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 手動補間専用の関数発生器を用いることな く、合成速度が補間関係に依存しない手動補間を実現で きる簡略な数値制御装置を提供する。 【構成】 複数のサーボ軸の補間送り可能な数値制御装 置において、手動パルス発生器の出力パルスに比例した 速度信号を、相互に補間関係にある複数の軸の合成運動 の送り速度指令としてパルス分配器に入力する手段と、 直線補間動作の終点座標をパルス分配器に入力する終点 座標発生手段と、パルス分配器に与えられた補間モード が直線補間の場合には、入力される速度指令と終点の座 標によって直線補間を行い、補間軸へ同期パルスを分配 し、前記補間モードが円弧補間の場合には、入力される 速度指令と、円弧終点座標と円弧半径、もしくは円弧中 心座標によって円弧補間を行い、補間軸へ同期パルスを 分配するパルス分配器と、前記同期パルスを位置指令信 号とする少なくとも2つのサーボ軸とを有する。 (57) [Summary] [Object] To provide a simple numerical controller capable of realizing manual interpolation in which a synthesis speed does not depend on an interpolation relation, without using a function generator dedicated to manual interpolation. [Structure] In a numerical control device capable of interpolating feed of a plurality of servo axes, a speed signal proportional to an output pulse of a manual pulse generator is pulse-distributed as a feed velocity command of a combined movement of a plurality of axes having an interpolating relationship with each other. Means to input into the vessel, If the end point coordinate generation means that inputs the end point coordinates of the linear interpolation operation to the pulse distributor and the interpolation mode given to the pulse distributor is linear interpolation, perform linear interpolation according to the input speed command and the coordinates of the end point. , When synchronizing pulse is distributed to the interpolation axis and the interpolation mode is circular interpolation, circular interpolation is performed according to the input speed command and the circular arc end point coordinate and circular arc radius or circular arc center coordinate, and the synchronous pulse is transmitted to the interpolation axis. And a at least two servo axes that use the synchronizing pulse as a position command signal.
