Development of an Automatic Scraping Method Based on Disk Milling Cutter Technology

This paper presents an automatic scraping method based on a disk milling cutter, aiming to replace the traditional manual scraping operation. The system utilizes a three-degree-offreedom CNC machine platform, combined with disc milling cutter processing technology. By adjusting the milling parameters, the milling cutter marks are used to simulate the cutter mark of manual scraping in different stages. The theoretical and simulation calculations of the cutting force generated during the machining process were carried out, which is consistent with the force required for manual scraping. The experimental results show that the number of high points (6,13, and 21 points/square inch, respectively) of this method in the rough scraping, fine scraping, and precision scraping phases meets the standard of manual scraping, and the processing efficiency is significantly improved. The study verifies the feasibility of scraping with disc milling cutters and provides an efficient solution for the automated scraping of guideways for machine tool.
