Manufacturing Methods and Technology Automatic Deburring.

摘要

The objectives of this Manufacturing Methods & Technology- funded project were to: investigate currently available deburring technologies; perform programming and deburring trials on 12 selected AGT-1500 components manufactured at Lycoming and recommend other deburring technology where the design of the component prohibits burr removal by robot; develop off-line programming and integrate it into the system; design fixtures for the 12 components; build fixtures for the air diffuser, forward header, and rear header; develop quality control criteria; provide a detailed cost analysis; collect data toward the development of the unit; develop an implementation plan; and prepare a final report. automatic (robotic) deburring can be implemented into production and provide substantial cost savings and quality improvements. The use of spring-loaded toolholders and carbide rotary files were found to be the best way to achieve uniformly deburred edges. The ASEA IRB L6/2 robot had faster response time, more rigidity and better maneuverability than the ASEA IRB 60/2 robot and is therefore more suitable for deburring applications of this type. A servo-controlled two-axis positioner used in conjunction with the robot is required to provide programming ease and deburring uniformity. Off-line programming shows promise of being able to provide programs which would require some touchup on line but would nevertheless, improve the productivity of the system. (kt)
