CNC milling is a manufacturing process in which computer-controlled cutting tools shape material according to a digital design. In dental production, milling machines can use job files to make items such as crowns, bridges, and templates. These files may include technical designs and, depending on how they are stored, information linked to a patient’s case.
Because digital job files connect design systems to physical production, they matter for both privacy and operations. Attackers who gain access to production archives may seek data for extortion or disrupt fabrication workflows. Defenses include limiting access to job files, separating patient information from production data where practical, and monitoring for unusual bulk file access or transfers. An exposure claim alone does not establish that CNC files were accessed or published.
