Study on super-long deep-hole drilling of titanium alloy.

INTRODUCTION

In this study, the super-long deep-hole drilling of a titanium alloy was investigated.

METHODS

According to material properties of the titanium alloy, an experimental approach was designed to study three issues discovered during the drilling process: the hole-axis deflection, chip morphology, and tool wear.

RESULTS

Based on the results of drilling experiments, crucial parameters for the super-long deep-hole drilling of titanium alloys were obtained, and the influences of these parameters on quality of the alloy's machining were also evaluated.

CONCLUSIONS

Our results suggest that the developed drilling process is an effective method to overcome the challenge of super-long deep-hole drilling on difficult-to-cut materials.
