Description
Technical field
The present invention relates to the Digit Control Machine Tool course of processing parameter collecting method that Based on Networked monitors in real time,
Belong to Digitized Manufacturing Technology field.
Background technology
In current fierce manufacturing industry global competition, plan of the most scientifically arranging production, maximum journey
Degree ground plays the utilization rate of manufacture equipment and seems more and more important.Additionally, the improvement of Technology is often
Set up in technological data bank on the basis of a large amount of statistical analysiss manufacturing field data on the other hand, and these
Accurately obtaining of data is always a bottleneck problem.For a long time, workshop lacks a kind of effective prison
Control means, the manual type traditional mainly by scene inspection, telephone contact, manual record etc. understands machine
Bed operating situation, lacks real-time and intuitive, and relies on manpower to carry out hand-kept and not only can consume
Take substantial amounts of manpower and time cost, and be difficult to ensure that the accurate of recorded process data and integrity.
At present, workshop on different lathes, uses different cutters and process program to specific component
Used cutting parameter is empirically determined, even if after cutting test trial cut by workman mostly
The rational cutting parameter decided succession in follow-up processing and reuse and also lack preferably ginseng
Number transfer means and normalized management method, empirical data is relatively strong to the dependency of personnel, on-the-spot number
Stop according to record, become scattered about in the minute book of different personnel, even without the record being correlated with, data can
Retrospective is poor.
By NC lathing install by the way of high-definition camera can with real time image collection workshop appliance and
The working order of personnel, can realize the operating to equipment by means of certain harvester and acquisition software
Situation carries out Real-time Collection, but still there is problems in that
(1) mode of image acquisition stores collection data volume greatly, and the data of collection mostly are top layer data,
The inherent operation information of controller cannot be collected.
(2) existing acquisition method compatibility is poor, it is impossible to contain all of control system distinct interface
The Digit Control Machine Tool of type, it is impossible to realize the comprehensive standardized management to workshop appliance.
(3) existing acquisition method is only limitted to the rotation of main shaft to the judgement of the running status of lathe, right
Limitation is also compared in the judge of other states, it is impossible to configuration adapts to different types of conditions of machine tool judgment rule.
(4) existing acquisition method reads the warning message of different lathe based on API, by CNC system
The impact of the language environment of system, API system and operating system etc., easily produces irreversible mess code
Phenomenon.
(5) existing acquisition method cannot realize machining state information (product designation, journey to product
Sequence number, cutter number, the speed of mainshaft set and feeding, rotating speed multiplying power, feeding multiplying power and machining
Time) Real-time Collection, the fabrication plan performance of product cannot based on gather data real-time assessment,
Integrated more difficulty between acquisition system and digitized workshop information system.
Summary of the invention
