Problems solved by technology

[0004] For the current batch processing process in the workshop, the tool change decision mainly depends on the experience of on-site workers. In addition, although the characteristic parameters of the cutting force, cutting heat, noise, vibration and other physical information of the tool can be extracted through various sensors to estimate the wear state of the tool, but this This method has high requirements on the stability and reliability of the sensor, and it is still unable to accurately guide the tool change under complex working conditions. A multi-information fusion tool change with timely data collection, rich effective information, and intelligent discrimination is proposed. decision making method

Embodiment 1

[0025] Processing workpiece: gear;

[0026] Machine tool: YS3118CNC5 five-axis CNC high-speed gear hobbing machine;

[0027] Sensor: WBQ212P71;

[0028] Terminal: iTouch121A(-T) embedded information terminal;

[0029] A / D converter: HTK-NDC1 Ethernet field measurement and control server.

[0030] The decision-making process of tool change in the batch processing of gears is as follows: figure 2 As shown, after replacing a new tool, the empirical life of the tool is set according to experience. After adjusting the machine tool to process a qualified product, set the power information consumed by processing this workpiece as a standard value, and store it in the computer or embedded terminal as the basis for subsequent power information identification. Every time a workpiece is processed, the power information of this processing is processed and compared with the standard power data to obtain the power status of this processing. If necessary, conduct random inspection on t...

Abstract

The invention provides a multimodal fusion based gear machining process tool change decision method. The method includes: performing multi-information fusion processing on tool experience life, power information of the machining process and quality data acquired by workpiece sampling inspection in the batch machining process of gears, and judging the current status of a tool so as to decide whether or not to change the tool. The information acquisition method is simple, stable and low in cost, and normal machining is unaffected; the acquired data are high in accuracy, response is fast, and an operator can be reminded of changing the tool in time; monitoring of machining quality, power information and tool life is combined organically, the tool can be changed under the optimum status, the machining quality is guaranteed favorably, high tool cost is lowered, and machining efficiency is increased. The method can be widely applied to gear machine tools and automatic production lines for gear machining.

Description

technical field [0001] The invention relates to the fields of machinery manufacturing, network and communication technology, and information processing technology, belongs to information collection and signal processing methods in manufacturing execution systems, and specifically relates to a tool change decision method in gear processing based on multi-mode fusion. Background technique [0002] The tool change process in the batch gear machining process is complex, which affects production efficiency. At the same time, the tool price is very expensive. How to make tool change decisions through the collection of effective information largely determines the work efficiency and processing quality of the automated production system. Modern manufacturing enterprises must have the ability to quickly respond and deal with abnormal problems with tools, so as to maintain and improve the business competitiveness of modern enterprises. It is necessary to monitor the status informati...
