numerical control system for simultaneous command more tools or axes of one or more machine tools

摘要

A system for the numerical control of a plurality of machine tool positioning units by a single instruction program, comprising a reading unit which reads program data comprising addresses and numerical data from a record member and issue the data in succession at an output, and a plurality of positioning units connected to receive data from the output. Each positioning unit is adapted to recognise its own address among the addresses which appear at the output and to enable a corresponding input for the reception of numerical data following the address. Each positioning unit is also able to operate during the reading of the addresses and numerical data following and/or concerning the other positioning units.
