Among them, the deviation data of the processing size can only be displayed on the workpiece model of the controller (such as a computer). When it is judged that the workpiece needs further processing according to the obtained deviation data of the processing size, the workpiece must be returned to the workshop, re-clamped, and re-installed. Processing, this process is not only cumbersome and inefficient, but also the error of re-clamping will also affect the machining accuracy of the workpiece

Embodiment Construction
[0021] The present invention will be described in detail below with reference to the accompanying drawings. It should be pointed out that the present invention can be implemented in many different ways and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to enable those skilled in the art to understand more thoroughly the content disclosed in the present invention comprehensive.
[0022] refer to figure 1 , figure 2 , a method for on-line measurement and processing of the surface of a workpiece, comprising: step 110 (ie step 1): using a measuring device to scan and collect a surface model of the workpiece; step 120 (ie step 2): the surface model of the collected workpiece The model is compared with the theoretical model of the workpiece, and the machining allowance required by the surface model relative to the theoretical model is calculated; step 130 (that is, step 3): project the machining allowance onto th...

A method for online measurement and processing of a workpiece surface, comprising the following steps: step 1: using a measuring device to scan and collect a surface model of the workpiece; step 2: comparing the collected surface model of the workpiece with a theoretical model of the workpiece, And calculate the machining allowance required by the surface model relative to the theoretical model; Step 3: Project the machining allowance onto the workpiece surface. The method for on-line measurement and processing of the workpiece surface of the present invention not only performs on-line measurement on the workpiece surface, but also directly projects the calculated on-line measurement result and the machining allowance between the theoretical model to the workpiece surface, which can be used for ongoing The processed workpiece is provided with online processing guidance, so the processing steps can be reduced and the production efficiency can be improved. In addition, since multiple clamping is not required, the processing accuracy of the workpiece can also be improved. The invention also provides devices and equipment for implementing the method.
Description
technical field [0001] The invention relates to the field of machining, in particular to a method for on-line measurement and processing of the surface of a workpiece. In addition, the invention also provides devices and equipment capable of executing the method. Background technique [0002] A 3D scanner (3D scanner) is a scientific instrument used to measure and analyze the shape (geometric structure) and appearance data (such as color, surface albedo, etc.) of an object or environment. The collected data are often used for 3D reconstruction calculations. It has been widely cited in the fields of industrial design, reverse engineering, robot guidance, etc. [0003] In the field of machining, three-dimensional scanners are usually used to detect the size of the workpiece. Generally speaking, after the workpiece is processed, the workpiece is transferred from the processing workshop to the inspection workshop, and the geometry of the workpiece is detected offline. Gives th...
