ABSTRACT:
The tool feed rate correcting method for numerical control system and the apparatus therefor according to this invention correct the feed override values using an override correction coefficient which is calculated from the displacement information of the tool and control the tool feed rate so that machining loads can be maintained within predetermined range irrespective of the machining conditions. This invention is therefore effective in realizing machining with a high efficiency as well as in reducing the cost.
