Design and Manufacturing of Automatic Scraping Mark Units Based on Laser Ablation Technology

Scraping is a crucial process in the surface finishing of machine tool guideways, significantly enhancing machine tools’ assembly precision and is widely adopted in the heavy-duty machinery manufacturing industry. Traditionally, scraping is a manual process with inherent limitations, necessitating the shift toward automatic scraping as a developing trend. Laser surface texturing, a novel research direction in the field of machine tool guideways, offers a promising alternative. This study briefly explores integrating laser surface texturing technology into an automatic scraping scheme. We designed laser scraping mark units based on the standard model of manual scraping marks, determined the laser processing parameters and schemes, conducted practical processing using laser marking equipment, subjected the processed samples to grinding and polishing, and finally examined the surface morphology of the samples using a confocal microscope to observe and evaluate the processing outcomes. The experimental results demonstrate that laser ablation can successfully produce laser scraping mark units according to the predefined morphology, thereby preliminarily validating the feasibility of automatic scraping via laser ablation.
