External numerical control milling machine intelligent coding control system

Abstract

The invention provides an external numerical control milling machine intelligent coding control system comprising a numerical control system, monitoring video heads, a three-dimensional image modeling device, an instruction corrector, a code analyzer, a central control table, a human-computer interaction interface and a database. The numerical control system, the instruction corrector, the code analyzer, the central control table and the human-computer interaction interface are connected in series in turn. The central control table is also connected with the three-dimensional image modeling device which is connected with multiple monitoring video heads. The multiple monitoring video heads are installed at different positions on a numerical control milling machine and are aligned with the working positions of the numerical control milling machine. According to the external arrangement, arrangement of the numerical control milling machine in the prior art does not need to be changed so that enterprise acceptance degree is high and market prospect is great; and the three-dimensional image modeling device and the central control table are arranged so that manual coding can be performed by users, automatic coding can also be performed by the system and thus a solid basis is laid for comprehensive automation, and convenient use of the system is not influenced by immature realization conditions of automation.

[0002] In the existing technology, the programming of CNC milling machine requires professionals to study each point carefully after obtaining the size of the workpiece, then set the processing plan, and then perform coding. In this process, the professionalism of the operator is very important, because this process must be The labor cost of the enterprise is very high for highly professional people to operate, and for more complex structures, the code is very long, the operation is difficult, and it is very easy to make mistakes. It is also very difficult for the operator to review after the code is completed. This also entails high time costs and associated risks

[0003] On the other hand, as a kind of CNC machine tool, CNC milling machine is mainly based on various instructions supported by the CNC system. These instructions even include process control such as condition judgment and cycle, but except for a few specially designed full-function CNC milling In addition, most CNC milling machines only provide a fixed instruction set. For the same or similar operations, CNC milling machine programmers, for example, repeatedly write a lot of codes. error, and because the general CNC milling machine only considers the more obvious error handling, it does not deal with some coding errors that do not affect the execution of instructions, and programmers can only write fixed execution instructions, which cannot be effectively executed. Effectively deal with these coding errors that do not affect the execution of instructions, so often a large number of workpieces become waste parts due to coding errors but can be effectively executed. Components that become scrap are put directly into service, resulting in substantial losses

The price of a specially designed full-function CNC milling machine is also quite high, and the CNC milling machine that can make up for the above problems appeared late, so it is difficult for companies that use a large number of fixed instruction set CNC milling machines to accept the high equipment purchase costs brought about by replacement equipment. deal with risk
