Problems solved by technology

Single-sensor measurement has its limitations: CCD-based three-dimensional measurement is fast, but the measurement accuracy is not high; laser non-contact scanning measurement is easy to use and fast, but it cannot effectively extract the surface boundary, and there are scanning blind spots on complex surfaces; High measurement accuracy, but the measurement speed is slow, and there are many manual interventions in the measurement process
Therefore, single-sensor measurement is difficult to quickly and accurately extract the geometric feature information of the target object

Embodiment Construction

[0017] The structure of the profiling processing system based on multi-sensor integrated measurement is shown in Figure 1. The detachable multi-sensor measuring spindle 4 and the copy milling machine main shaft 3 are installed side by side on the Z-axis 2 of the copy milling machine structure body 1, the multi-sensor measuring spindle 4 is detachable, and it is installed on the copy milling machine Z by fixing screws 11 On the axis 2 (it is also possible to combine the structure of the profiling milling machine processing spindle 3 and the multi-sensor measuring spindle 4, and realize it by replacing the installation method. Through the standard machine tool spindle tool clamping and connecting accessories, the measuring sensor on the multi-sensor measuring spindle 4 is directly It is installed on the processing spindle 3 of the profiling milling machine to carry out the measurement work. When the profiling processing is required after the measurement work is completed, the pro...

Abstract

A profile-manufacturing method based on multi-transducer integrated measurement includes utilizing CCD photographic measurement to make rough measurement on object to obtain rough 3-D geometric data of object, guiding said data into 3-D rebuilding module (RM) in universal format, rebuilding rough 3-D model of object by processing viewpoint group, using laser measuring head and contact measuring head to obtain accurate 3-D geometric data of object based on said rough 3-D model, guiding said accurate data into 3-D RM in UF to obtain accurate 3-D model of object then revising obtained model according to requirement.

Description

technical field [0001] The invention relates to a profiling processing method and system, in particular to a profiling processing method and system based on multi-sensor integrated measurement. Background technique [0002] Profiling is an effective processing method in the field of mold processing. The traditional profiling process adopts the profiling method, that is, the position signal is obtained by contacting the profiling head with the surface of the target object, and after conversion, the tool is driven to perform processing. With the rapid development of electromechanical technology and processing technology, the traditional analog profiling processing method has been gradually replaced by numerical control profiling processing due to its low precision and slow speed. CNC profiling first obtains the geometric information of the measured surface through contact or non-contact three-dimensional measurement, and then the profiling system converts the measurement info...
