Integrated Manufacturing Variation Management (IMVM)
Abstract
The goal of the IMVM project was to generate an automated system by which a manufacturer can compensate for machine tool workspace (machine tool) errors induced due to part, fixture, tooling, or machine tool errors. An automated process would drive significant reductions in new part and new fixture setup times, and identifying parts delivered with significant variations, in turn minimizing machining requirement to bring the parts within specific parameters, reducing the number of scrapped parts, manual intervention and machining setup time. The innovations from IMVM Project are focused on improving the present state of technology, yielding significant process improvement directly impacting reliability on parts, reducing the time to determine whether a part can be brought within specifications by machining, or quickly identifying if a part needs to be scrapped or returned to the supplier before spending man hours machining a part in an attempt to bring it into required specifications. To address the goal, two major technologies have been developed and validated from this project. First one is machine tool Volumetric Error Compensation (VEC) technology to measure machine tool error, generate error model and compensate the error through machine compensation table. Second one is Adaptive Machining (AM) technology using compensated tool path to accommodate the geometric variations on the incoming parts.
