Evaluation of the shape of the FRP hole processing drill manufactured in-house and the X-ray CT assessment of the processed material.

Comparative evaluation of the conditions before and after processing using a φ15mm drill for in-house processed FRP and commercially available drills through visual inspection and non-destructive testing!

This document is a technical report that evaluates the characteristics of drill shapes after processing, using hole processing of FRP as an example. It quantifies the features of the processed drill shapes produced in-house and provides a quantitative comparison of these shapes with commercially available drills, as well as assesses the validity of the shapes through FRP processing. In the scope evaluated this time, although no superiority was recognized between the commercially available drills and the modified in-house drills for FRP processing, it was confirmed that the shape of the in-house processed drills contributes to extending the tool life. From the perspective of extending tool life, this resulted in findings of significant importance. 【Contents of the report (Evaluation preparation, methods, and results)】 ■ Preparation of evaluation drills ■ Shape inspection of evaluation drills ■ Production of flat plates for processing evaluation ■ Implementation of hole processing using various drills ■ X-ray CT measurement *For more details, please download the PDF or feel free to contact us.
