CNC machine tool scraping refers to a process of using machine tools for scraping processing, which is used to process flat, curved, or convex and concave shapes on workpieces. Commonly used machine tools include planers, milling machines, lathes, etc.

　　The specific operating steps are as follows:

　　Determine the machining object: Select the workpiece that needs to be scraped.

　　Design scraping path: Determine the scraping path and draw the machining contour based on the workpiece requirements and machining tasks.

　　Select the appropriate scraper: according to the processing requirements and workpiece characteristics, select the appropriate scraper, including shape scraper, flat scraper, planer, etc.

　　Adjusting machine tool parameters: According to the scraping process requirements, adjust the feed speed, spindle speed, workbench movement speed and other parameters of the machine tool.

　　Fixed workpiece: Fix the workpiece on the machine tool and use a fixture or suitable fixture device to maintain the stability of the workpiece.

　　Calibrate tool position: By setting the coordinate system of the machine tool, correspond the position of the scraper to the surface of the workpiece.

　　Scraping processing: According to the designed path and contour, start the machine tool for scraping processing, and continuously approach the surface of the workpiece through the scraper to remove materials and form a predetermined shape.

　　Check the processing quality: After the processing is completed, check the quality of the scraped surface to ensure that it meets the design requirements.

　　Cleaning and maintenance: Clean the machine tool and scraper, and carry out necessary maintenance.

　　When performing scraping machining on CNC machine tools, attention should be paid to the control of scraping direction, scraping speed, and scraping depth to achieve ideal machining results and ensure the safety of operators.
