Title:
NUMERICAL CONTROLLING SYSTEM
Document Type and Number:
Japanese Patent JPS5824905
Kind Code:
A
Abstract:
PURPOSE:To improve the working efficiency of a numerical controller, by performing write processing of a command program to an internal memory and read of numerical control data in parallel. CONSTITUTION:Numerical control NC data of one block are read out from a paper tape 101 by driving a paper tape reader 102 and inputted to a processing section 104. The processing section 104 writes this data to an internal memory 103 for NC processing. If the NC data is, e.g. a numerical data representing a position, a pulse distribution circuit 105 outputs distribution pulses Xp,Yp and Zp based on the input value, drives a motor of each axis with servo circuits 106X- 106Z, positionings a tool and moves it in accordance with a command path. When the circuit 105 is finished for the pulse distributing calculation, a distribution completion signal comes to the processing section 104, then the section 104 writes the command program to the internal memory 103 and performs the read of the NC data of the next block to the reader 102.
