| Outline of Final Research Achievements |
In order to apply cutting using micro end mills to microneedle array molds, blind conical holes drilling experiment were performed on mold steel.As a result, it was found that increasing the spindle speed and reducing the feed rate are effective in reducing tool wear.It was clarified that more than 100 blind holes can be cut with one tool by optimizing the cutting edge shape and cutting conditions of the end mill.
