Quality detection method for precision CNC machined products

Abstract

The invention discloses a quality detection method for precision CNC machined products. The method comprises the following quality detection steps: S1, preparation of detection tools: a precision CNCmachined product, a CCD camera system, a three-coordinate measuring machine, a rotating platform, an electronic balance, a data input system, a data statistics system and a computer are included, wherein the CCD camera system, the three-coordinate measuring machine, the rotating platform, the electronic balance, the data input system and the data statistics system are all connected with the computer; and S2, weight detection: the precision CNC machined product is weighed for multiple times by placing multiple surfaces of the precision CNC machined product as bottom surfaces on the electronic balance according to the shape of the precision CNC machined product, the highest value and the lowest value of multiple pieces of weighing data are removed, the multiple intermediate values are averaged, and the obtained numerical value is input to the computer through the data input system. The method is reasonable, the quality of precision CNC machined products is comprehensively controlled through multiple detections, and the method is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of quality detection of precision CNC processed products, in particular to a quality detection method of precision CNC processed products. Background technique [0002] General CNC machining usually refers to computer digital control precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. CNC is also called computer gong, CNCCH or numerical control machine tool. It is actually a name in Hong Kong, China. Later, it was introduced to the Pearl River Delta of the mainland. It is actually a numerical control milling machine. Some people in Guangzhou, Jiangsu, Zhejiang and Shanghai call it "CNC machining center". One is a new type of processing technology. The main job is to compile processing programs, that is, to convert the original manual work into computer programming. Of course, manual processing experience is required. Numerical control m...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, after the workpiece is processed, the precision CNC processing product needs to be inspected. The existing inspection is generally observed by human eyes, and then detected by an instrument. The error of detection is relatively large, and it is necessary to For the problem of error compensation, a quality inspection method for precision CNC machining products is proposed
