摘要

Many machining and measurement operations require the part to be held in a fixtures that are specifically designed and built for a specific part becomes expensive when many different types of parts are to be processed Flexible part fixtures are time consuming to set up and generally do not offer the part stability that larger parts often require. The current state of the art in flexible part fixtures for lightweight applications include expensive adjustable towers positioned manually by the operator or automatically by a coordinate measuring machine (CMM) to component fixtures consisting of v-blocks, c-clamps, double-sided tape, vacuum cups, and spacer blocks. Some fixtures are positioned in a grid pattern thus limiting the fixture placement to the spacing of the grid. Other systems require the fixture to be locked down to the machine base with a clamp but placement is only limited to the size of the fixture base.
