碩士 === 國立虎尾科技大學 === 機械設計工程系碩士班 === 106 === This research primary intention for establishes a set of CNC milling machine on-line gauging system, after the actual processing, after may gauge the processing immediately the milling depth, and may figure out the milling depth immediately the extent of the error, uses this gauging system to be possible effective to reduce the gauging work piece the time cost. This research gauging system uses the way for the non-contact gauging, the use measuring instrument for the laser displacement idea, matching is the VB formula, the gauging experiment divides into two parts, the first part for confirms this gauging system using the slip gauge the system error, its gauging method for the use different way gauging mechanical zero point to the platform distance value, the gauging result may obtain the gauging measuring accuracy is 0.0455mm; The second part for gauges the work piece, its gauging method for uses the work piece the height difference, take the first gauging as the datum, then makes the second gauging, penetrates two time gauging to carry on the computation, may obtain the work piece actual milling depth, again carries on the computation with the design size, finally may obtain the gauging extent of the error. This gauging system highly repeatability error maximum value is 0.0162mm, the minimum value for - 0.0065mm, the measuring accuracy is 0.0228mm.
