Embodiment 1

[0031] In this embodiment, an automatic processing quality closed-loop control method is specifically provided to realize the quality closed-loop control of thin-walled and weakly rigid parts, and the processing accuracy can be controlled at ±0.02mm. This control method is mainly based on MES system and automated processing production line, among which, the MES system is the production process execution system of the manufacturing enterprise, which is a set of production information management system oriented to the execution layer of the workshop of the manufacturing enterprise; the automated processing production line refers to the realization of the product process by the automated machine system A form of production organization. It is formed on the basis of the further development of the continuous assembly line. Its characteristics are: the processing object is automatically transferred from one machine tool to another machine tool, and the machine tool automatically per...

Abstract

The invention discloses a quality closed-loop control method for automatic machining, and belongs to the technical field of quality detection. The method comprises the following steps that feeding motion for a workpiece is carried out by a robot, and clamping for the workpiece is completed on a machine tool; on-machine detection is carried out on clamping data of the workpiece through an on-machine detection head, and feedback is sent to a MES system, if clamping precision requirements are not met, an instruction is sent to the robot through the MES system, and the robot performs stripping action, thus finishing the flow; if clamping precision requirements are met, the machine tool is started, then the workpiece is sent to a three-coordinate measuring machine for size detection after beingmachined, and feedback is sent to the MES system for judging whether the workpiece meets requirements on size and precision, if yes, the flow is finished; and if not, cutter compensation informationis acquired by the MES system, and the information is sent to the machine tool. According to the method, quality closed-loop control is carried out on the machining flow of the workpiece, thus improving quality control of thin-wall shell pieces during the automatic machining process so as to achieve the purpose of machining precision improvement.

Description

technical field [0001] The invention belongs to the technical field of quality inspection, and in particular relates to an automatic processing quality closed-loop control method. Background technique [0002] In the entire life cycle of a product, there are many quality activities in each stage, and a large amount of quality information is generated. Some information is output from this stage, sent to the next stage, and becomes the input of the next stage, and some information in the next stage is fed back. Going back to the previous stage, the closed-loop control system uses this feedback to compare the output with the input to obtain the optimal output result. [0003] In the automatic processing process, factors such as tool wear, clamping error, and machine tool error will cause processing errors and cause product out-of-tolerance. [0004] At present, the spinning method is used for thin-walled and weakly rigid parts, so the stress state is inconsistent. The thin-wal...
