The system employs a screwdriving mechanism that integrates both torque and depth monitoring to ensure proper fastener seating and detect integrity issues with the receiving boss. By establishing a dynamic depth window for applied torque, the system can differentiate between a correctly tightened fastener and one that has stripped its mating thread in the boss, which would otherwise exhibit similar torque characteristics. Parts failing this cross-check are marked for rework, preventing the propagation of assembly defects and enhancing product reliability.","language":"en","published_at":"2026-09-15T11:52:55.891144Z","canonical_url":"https://opentechnical.org/p/OT-2026-000000052","status":"PUBLIC","supersedes":null,"keywords":["screwdriving","torque monitoring","depth sensing","boss stripping","assembly automation","fastener verification","rework marking","process control"],"extent":{"words":2597,"paragraphs":12,"figures":2},"hashes":{"canonical_text_sha256":"d98baf6f4e283930b4b42987455b6f703f1a207c56d81bdff92fbcf99d7817d9","html_sha256":"9c1b452a017f04e3fd2c17ed09a13a56f1c6955d327f69c3291b1b2ec937ed09","pdf_sha256":"1c9ecf788f2ba3ee17faa5335a6f973500281f6adb1f98535ec97c4576a480c1","markdown_sha256":"f031e401c1e266b028c94d5d632e3988f6a10b122e7916f1d4a2e105e4cfdef1","manifest_sha256":"60f85c936229c2335d395225222a5325a1d85aa73a70e3aff3ec9de46d60ed44"},"links":{"html":"https://opentechnical.org/p/OT-2026-000000052","text":"https://opentechnical.org/p/OT-2026-000000052/publication.txt","markdown":"https://opentechnical.org/p/OT-2026-000000052/publication.md","pdf":"https://opentechnical.org/p/OT-2026-000000052/publication.pdf","manifest":"https://opentechnical.org/p/OT-2026-000000052/manifest.json","signature":"https://opentechnical.org/p/OT-2026-000000052/manifest.sig","integrity":"https://opentechnical.org/p/OT-2026-000000052/integrity"},"categories":[{"category_id":"CAT-000000273","path":"manufacturing-assembly-equipment/assembly-systems/screwdriving-systems","name":"Screwdriving Systems","primary":true},{"category_id":"CAT-000000269","path":"manufacturing-assembly-equipment","name":"Manufacturing & Assembly Equipment","primary":false},{"category_id":"CAT-000000270","path":"manufacturing-assembly-equipment/assembly-systems","name":"Assembly Systems","primary":false},{"category_id":"CAT-000000093","path":"tools-tooling/fastening-tools/torque-tools","name":"Torque Tools","primary":false}]}
