Abstract
A machining load monitoring system to monitor a machining condition by comparing sampled data of a machining load in a trial cutting process and measured data thereof in an actual cutting process with each other precisely with respect to time. An NC command executing unit (1) executes NC commands, and updates a block number and an execution mode in an executed state table (2) when the execution of NC commands of one block is finished. A load monitoring unit (4) compares sampled data, stored in a sampled data table (3), of a machining load in a trial cutting process with measured data thereof in an actual cutting process at given intervals of time. When the block number in the executed state table (2) is updated, sampled data of a new block number are read from the sampled data table (3). The sampled data in the trial cutting process and the measured data in the actual cutting process are compared with each other at predetermined times, and an alarm is issued when the difference between the compared data reaches or exceeds a predetermined level.
