Cut, then labor intensity is larger, production efficiency is relatively low, and production cost improves.It is therefore desirable to existing traditional Numerical control cutting volume
Cheng Fangfa is improved, and improves production efficiency, reduces production cost.
In every engineering that my company accepts in recent years, due to inside high-level structure pillar internal partition design be mostly ring flat-plate or
Person's square plate.And the quantity of these internal partitions is more, part is thicker.In steel box girder, diaphragm plate quantity of typically cornicing is more, and zero
Part is larger.Traditional baiting method is that each part will perforate, and could completely be cut, not only cutting efficiency is low, and cutting torch
Wasted with cutting gas serious.So as to cause blanking excessive cycle, making progress is influenceed.It is therefore necessary to Numerical control cutting is programmed
Method is improved, and to improve cutting producing efficiency, and then ensures being smoothed out for duration of a project.
The content of the invention
The defects of the technical problem to be solved in the present invention is to be directed in the prior art, there is provided one kind improves Numerical control cutting effect
The method of rate, this method can reduce pre- hot piercing, reduce cutting path, to improve Numerical control cutting efficiency, be reduced so as to reach
The purpose of production cost.
The technical solution adopted for the present invention to solve the technical problems is：A kind of method for improving Numerical control cutting efficiency, bag
Include following steps：
Step 1)：Part drawing is drawn in FastCAM programming softwares, saves as CAM file, or directly read in CAD software
The DXF/DWG part drawings of drafting, the optimization processings such as necessary removing compression are carried out, also save as CAM file；
The part drawing of the drafting must follow following rule：The part drawing for handling closure well is arranged on a horizontal line
On, common side, bridge joint, continuous cutting process are carried out to figure according to being actually needed；
Step 2)：CAM file is read in FastNEST programming softwares and carries out part whole plate programming；
Step 3)：Automated programming, generation NC cutting files are carried out using FastPATH programming softwares；
Step 4)：Actual cutting process is simulated using FastPLOT correction verification modules, figure and size are verified, and
Cutting cost statistics calculates.Cutting track shows, simulates actual cutting process, automatic positioning function, the verification of designated program row and
Modification, after verification is errorless, NC cutting process is submitted to numerical control cutting machine and carries out Numerical control cutting.
By such scheme, in the step 2), CAM file progress part whole plate volume is read in FastNEST programming softwares
Mode also is handled as follows to part drawing during journey：The word in part drawing is deleted in FastNEST programming softwares and part is compiled
Number；Unnecessary repetition lines in part drawing are deleted in FastNEST programming softwares；Not closed figure is linked together；To can not
The figure of identification blows its part drawing.
The beneficial effect comprise that：
1) circuit is cut by program optimization, reduces flame-perforated quantity and cutting running length；
2) situation such as numerical control arcing operationally, flame-out is reduced；
3) pre- hot piercing 70% can be directly reduced using modes such as side altogether, bridge joint, continuous cuttings, reduces cutting path
30%, improve cutting efficiency 40%, improve steel jacking utilization rate 3% -7%, meanwhile, effectively save flame, cutting torch electrode,
The consumptive materials such as laser lens and the consumption for saving water, electricity and gas equal energy source 40%；
4) continuous cutting function can substitute bridging functionality, make adjacent several parts accomplish continuously to cut, avoid pre-
Hot piercing, so as to effectively save cutting torch, oxygen is preheated, saves consumptive material, improves Numerical control cutting efficiency；
5) time is significantly saved with manually, improves operating efficiency.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing：
