Micro-hole array processing using laser irradiation off-time control was studied to obtain excellent machining shape without thermal damage during laser drilling of CFRP. When continuous micro-holes are machined, closer hole spacings worsen the machined shape owing to thermal damage. For a microhole, a single point is repeatedly irradiated with a laser. The laser irradiation off-time control method sets the laser off time for a set of irradiations, which suppresses heat accumulation and prevents thermal damage. This technique was used to process a micro-hole array with a hole spacing of 0.3 mm without thermal damage. Furthermore, the laser off-time was applied to the laser scanning method, which has a laser off-time for each set of laser scans, and a micro-hole array with a hole spacing of 0.14 mm was fabricated without thermal damage. For small hole spacings, the laser scanning method using the laser off-time yielded better machining results than the laser irradiation off-time control. The laser scanning method was unsuitable for this experimental setup when the hole spacing exceeded 0.4 mm. The laser irradiation off-time control method was suitable for large hole spacing.
