Purpose Of Blackplot Editor

[Ashish B]

Hi...

Backplot editor creates a 3d toolpath image of NC codes, but Can anyone let me know the Application of Backplot Editor?.



I mean to express that what situations/conditions a Backplot editor is used?

It is a basic tool path simulation to add visual inspection before running a program in the CNC.

I guess that it will be useful in the following mentioned Condition -

If a Power goes off, it is impossible for operators which cannot track the Tool Position in relation to Toolpath. For New Machines the machine controller shows the Absoulte position of the Tool (with respect to G54 position ) but on older machines the machine control does not shows any Absolute Position .

Its a matter of guess & specfically when there are number of Pockets in a Particular Program & where the Z movement cannot be traced because of the Number of pockets & in such case the Guess can be VERY VERY RISKY.



I guess in that case, the operator can create a Replication of the Toolpath ( which is trimmed after the Power recovery State ) so that the Operator can easily & visually understand that whether he has correctly trimmed it or not.


Also i need to ask you u that does the Backplot Editor software defines Z position after selecting that particular toolpath just as what is Possible in Any CAM software ?

I downloaded NC Plot Editor Software but there was never a provision of any such Feature which can enable us to check the Z ( Or X & Y positions ) in that Toolpath.

Is there any software in the market which has the above mentioned feature?.

For New Machines the machine controller shows the Absoulte position of the Tool (with respect to G54 position ) but on older machines the machine control does not shows any Absolute Position .
Many machines can count the number of lines that have been executed. Others have sequence numbers on each line of code (N1234 as an example)
9 times out of 10, if the power goes OFF while the tool is incut - the part would be scrapped ( spindlehead dropping and dwell marks are the main causes )

Its a matter of guess & specfically when there are number of Pockets in a Particular Program & where the Z movement cannot be traced because of the Number of pockets & in such case the Guess can be VERY VERY RISKY.
A good operator can backtrack the NC-code from the stoppage point back to the point before entering into that cut above the part, For ease and safety, he would re-run the code again. Yes, CAUTION shoud be shown on a program re-start, and should not be done by untrained personnel

I guess in that case, the operator can create a Replication of the Toolpath ( which is trimmed after the Power recovery State ) so that the Operator can easily & visually understand that whether he has correctly trimmed it or not.
No change required to the program

BACKplot editor is just that, a text editor with graphic capabilities, some have nice bells and whistles to "optimise" toolpaths

Yes, the machine it is meant to run on.
Plus the positions can usually be read from the code ie X123. Y45. Z-10. is a point in 3D space [123,45,-10] with [0,0,0] being the origin

A backplotter is a "graphics tool" used by programmers, toolsetters and operators to check if the code will not do any "strange moves" before the program is loaded onto the machine. This is to also save setup time to wheadle out little simple mistakes. The accuracy and depth of information that the software reports back to you reflects in the cost of the software. The basic backplotting "tool" will not tell you the toolpath will stuff the part, it still needs an experienced eye to be the judge.

Going by a lot of your queries, can I assume you have NO actual machining experience on manual or CNC machines???

If your idea of CNC programming is to use a CAM program then you may not fully appreciate what a back plotter can do for you.

If you do any amount of CNC programming with a text editor, a back plotter can save a lot of tools and spindle bearings.
And if you do any macro B programming NCPlot is the only affordable plotter available.

And even CAM programs produce bad code now and then.

Hi ,


Well i was not aware of any feature in NC machine which counts the Number of Lines Executed. How to Access to that feature. Is it a Parameter Number which stores the LINE COUNT ?.

How a NC Plot Editor helps in Macro Programming & can u mention a software name which provides Aid for Macro Programming?.

Ash

Thank you for your TIME, PATIENCE & SUPPORT.

Depends on the control, old line stuff like Fanuc, and Mitsubishi are, I think, falling behind in these types of features.
Here is an example of how it is done in a newer PC based control.

NCPlot helps by being able to plot stuff like this so you can have an idea it is going to work before going to the machine.

Well Thanks for the Information Regarding Backplot Editor.

Is there any Backplot editor which can show a replication of Wire Cut Programs ( which are having U & V Codes...a TAPER Program ) in the
Market?


Thanks for your TIME, SUPPORT & PATIENCE

Hey Guys,

The Software which supports back plotting of Wirecut Program can be found at -

http://www.ebair.com/downloads.htm

Download the product - editNC "The NC Programmers Editor of Choice" (v8.9.0) from the website to get a Wirecut Program Simulated.

Thanks
Ash
