Based On The Laser Ranger Scanning Measurement System On The Machine

With the rapid development of high-precision manufacturing and testingtechnology, the detection of large panels out of the offline detection processingequipment has gradually showing his shortcomings and disadvantages of theapplication of traditional manual measurement， the measurement of thecoordinate measuring machine not only increases measurement error but alsoincrease the measurement time. So the machine measurement technology tofundamentally improve the measurement accuracy but also speed up themeasurement speed, accuracy and efficiency of CNC machining equipmentgreatly improved. Today in machine measurement technology at home and abroadmainly depend on the contact probe to complete the workpiece detection, but thecontact measurement has great strength, not easy to control and measurementspeed slow and so on shortcomings, so the development and application of laserrange finder on machine measurement system is very necessary. According to thecharacteristics and function of laser scanning software at home and abroad oflaser range finder based on machine measurement system development, putsforward Geomagic for surface reconstruction and the combined method of UG,the laser extraction of2d data to3d conversion, and the software in machinemeasurement system of each function module carried on the detailedintroduction.This stage at home and abroad in the machine measurement techniques relyon the contact probe head to complete the detection of the workpiece measuringforce and is difficult to control and measuring slow shortcomings contactmeasurement, the laser rangefinder can measure softer objects and developedmeasurement speed.It can be achieved to measure the small size workpiece holes,slots, arc, development and application of laser range finder machinemeasurement system is very necessary. Time-consuming and labor-intensive for large mold cover application CMMdetection, increased testing costs, we use on-line measurement method based onlaser range finder, the hardware devices in the machine measuring system withmeasurement software research, the developed machine measurement system tobe applied to a variety of point laser range finder, and application of the COMETL3D optical measuring instrument to verify their results, the measurement resultsmeet the requirements of the mold manufacturing, the application of this on-linemeasurement systems to solve application of traditional CMM the inconvenienceof off-line testing, reduce testing costs in the machine measurement technologyplays an irreplaceable role in the processing and testing of the mechanical parts.
