Embodiment 1

[0035] Specific examples of automatic collection of progress status of batch processing machining tasks:

[0036] Processing workpiece: a motorcycle part

[0037] Machine tool: CKA6140

[0038] Sensor: WBQ212P71

[0039] Terminal: iTouch121A(-T) embedded information terminal

[0040] Analog / digital converter: HTK-NDC1 Ethernet field measurement and control server

[0041] Three working steps: ① Cutting the outer circular surface

[0042] ②Cutting end face

[0043] ③Cutting end face

[0044] In the drive system where the frequency converter drives the asynchronous motor, the process of collecting the progress status of the batch machining machining task is as follows: image 3 As shown, ① the present invention utilizes the power sensor to collect the power information output by the frequency converter; ② the sensor outputs an analog voltage signal of 0~5V, and outputs it to the A / D converter for analog-to-digital conversion to obtain a digital signal; ③ the A / D converter ...

Embodiment 2

[0046] Specific examples of automatic collection of progress status of single-piece machining machining tasks:

[0047] The hardware connection diagram is the same as batch processing, such as figure 1 Show. In the drive system where the frequency converter drives the asynchronous motor, the process of collecting the progress status of the single-piece machining machining task is as follows: Figure 4 shown. Its data acquisition method is the same as batch processing. The terminal automatic collection method is:

[0048] ① Before processing, it is found that the no-load database does not exist, start the machine tool, use different speeds, and obtain the no-load power at all speeds to form a no-load power database; ③ Add the theoretical cutting power and the no-load power at the corresponding speed to obtain the theoretical power curve; ④ When the workpiece is processed, obtain the power curve of the main motor of the machine tool, and compare the proportion of the actual ...

Abstract

A method for automatically collecting the process state of mechanical machining mission based on machine power information can resolve the data collecting problem of on-site control layer of information system of prior producer. The method automatically collects the process state of mechanical machining mission according to the change and repeat of power information, information character, and period character of main motor of the machine. For batch machining mission, the method comprises that (1), recording the power curvature in teach process, analyzing and extracting information character, (2), comparing the power curvature and the information character of same batch after teaching with the teach, to obtain the process state information of mission. For single element, the method comprises that (1), building an idle database, (2), calculating the cutting power, (3), forming a similar power curvature, (4), comparing real power with similar power, to automatically obtain the process state of the work piece.

Description

technical field [0001] The invention relates to the fields of machinery manufacturing and communication technology, and belongs to information collection and signal processing methods in manufacturing systems; in particular, it relates to a method for automatically collecting progress status of machining tasks based on machine tool power information. Background technique [0002] The so-called machining production task is the plan to confirm the production quantity of each specific final product in each specific time period. Based on customer contracts and market forecasts, the production plan concretizes the product system in the business plan or production outline, making this a link between the transition from the material requirements plan to the specific plan. [0003] At present, most manufacturing enterprises have implemented enterprise informatization projects to speed up the pace of enterprise development. However, some difficulties were encountered during the impl...
