This paper presents a method of real-time adaptive control of drilling and tapping for the difficult-to-cut materials such as superheat resistant alloy (Inconel718). Real-time adaptive control such as adaptive pecking is effective for these materials. In tapping process, normally adaptive control has disadvantage to be applied because C-axis requires high acceleration in the process. In general, conservative cutting speed is applied to such difficult-to-cut materials, since high cutting speed intense tool wear. Moreover, only in the case with low cutting speed, C-axis is able to be operated with high acceleration to stop its rotation. By introducing adaptive control, chip jamming is avoided during drilling and tapping process.
