In a zone-based tolerance evaluation, the profile (or helix) is divided into two or more zones, and each zone is calculated separately and may have different tolerance classes. For example, a profile could be divided into a tip zone, a middle zone, and a root zone. A helix could be divided into a left end zone, a center zone, and a right end zone.
Internal helical threads are typically produced through multiple high-speed grinding passes. As the length of the thread and/or thread helix angle increase, so does the difficulty in maintaining process stability and thread accuracy when grinding these internal profiles.
