Embodiment 1

[0046] This embodiment uses the CNC machine tool tooling and workpiece matching inspection and processing control method of the present invention, and takes the CNC high-speed gear hobbing machine model YS3120CNC6 produced by Chongqing Machine Tool (Group) Co., Ltd. as the control object CNC machine tool to control the start-up processing of the CNC machine tool . The six-axis control and four-axis linkage CNC high-speed gear hobbing machine produced by Chongqing Machine Tool (Group) Co., Ltd., model YS3120CNC6, adopts Siemens (SIEMENS) 840D digital control system, and its motion axes are driven by independent AC servo motors and electronic gearboxes. Control indexing movement and differential compensation to realize generating method machining, suitable for cylindrical spur gears, helical gears (shaft gears, disk gears), worm gears, small taper gears, drum gears, splines, different modules and helix angles Double or multiple gears with different directions, single indexing, m...

Embodiment 2

[0055] This embodiment is an optimization scheme proposed based on the first embodiment. The CNC machine tool that is the control object in this embodiment is still the CNC high-speed gear hobbing machine model YS3120CNC6 that has undergone integrated transformation of tooling and workpiece identification functions in Embodiment 1, and also builds a matching inspection system based on a programmable device platform through logic programming; However, the difference from Embodiment 1 is that the matching verification system based on the programmable device platform in this embodiment not only includes the matching data storage module, matching reference processing module, matching object processing module, and matching verification processing described in Embodiment 1. module, and further added an information cache module, a task change judgment module, and an installation part replacement judgment module. The system architecture is as follows: image 3 shown. In the matching ...

Abstract

The invention provides a tool and workpiece matching verification system and a machining and controlling method of a numerically-controlled machine tool. When the numerically-controlled machine tool is started to perform machining, the numerically-controlled machine tool is not directly and normally started to be machined and directly and normally undergo machining and control operation, however, match verification is performed by the matching verification system through tools and workpieces used for machining of the numerically-controlled machine tool and machining technology parameters and machining control procedures set by the numerically-controlled machine tool. Whether the numerically-controlled machine tool can be started to perform machining or not is intervened and controlled by a matching verification result. Economic losses and machining accidents due to wrong installation of the tools and the workpieces or the fact that the machining technology parameters and the machining control procedures are not matched with required machining tasks are more efficiently eradicated in the process of machining of the numerically-controlled machine tool, and safety in machining of the numerically-controlled machine tool is ensured. Recording and storing of information of the matching verification result can be achieved, and basic data are provided for achieving information management of real-time monitoring, optimal scheduling of the machining tasks and the like of the information of machining and producing processes of the numerically-controlled machine tool by an enterprise.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing automation, belongs to processing process monitoring and control technology, and in particular relates to a CNC machine tool and workpiece matching inspection system and a processing control method. Background technique [0002] In the fast-paced, small-batch, multi-task CNC machine tool processing process, the frequently changing processing tasks correspond to a wide variety of tooling and workpieces, and there are large differences between various tooling and workpieces used in the same CNC machine tool. similarity. Tooling refers to the general term for various processing tools that may be used in the machining process of CNC machine tools, including cutting tools, fixtures, molds, measuring tools, inspection tools, auxiliary tools, fitter tools, station equipment, etc.; workpiece refers to CNC machining tools. The processing object in the process of machine tool processing ca...
