System for providing time control data in a numerical control system
First Claim
1. A system for providing time control data in a numerical control system comprising data memory means having a plurality of flags, a flag being provided for every time control item and activated only when said item is in active operation, clock means for providing signals at predetermined intervals, input device means for inputting command information to said memory, display/alarm means for displaying content of said memory and giving warning, means for counting said clock when a flag in said memory is activated and applying result of the counting to said display/alarm means, and control means for controlling operation of the above elements.

Abstract
In a numerical control machine tool, the time that the tool or bit actually operates is counted in the control device of the numerical control system. The present time control data collection system comprises a data memory having a plurality of flags, the condition of each of which reflects the actual operation of the related tool or bit, a real time clock which provides signals at predetermined intervals, and means for counting the real time clock on the condition that the particular flag in said memory is on. The counted value is displayed either directly, or the fact that the counted value exceeds the predetermined reference value is indicated. The present system can also be implemented using a programmed micro-computer.
