Parameter for Multiaxis Toolpaths other than "Classic"

[Mick]

I'm modifying a post processor to suit an Okuma MU500VA-II with a P300 control. I want to switch on TCP for the 5 axis toolpaths, but I'm not sure of a parameter (or a variable) that would indicate a 5 axis toolpath.

 

For the classic toolpaths it is a fine, because there is a predefined variable (I believe opcode worked fine for the classic toolpaths). I've got the post working nicely, aside from when I use any of the newer toolpath in surface/solid or from the toolbox.

 

Does anyone know of a parameter or variable for X6/X7 posts that basically says "hey, I'm either in 5 axis mode or I'm not" ?

Search the NCI and Parameter Reference Guide. The variable you are looking for is 'tool_op$'. This variable contains an integer value that indicates the exact Toolpath type.

I've used tool_op$ but it returns the same value for surface-solid parallel cuts or parallel to surfaces, that being 440.

You will need to create a parameter read function to capture parameter number 15583.

 

15583 will hold a string with the name of the toolpath.

 

I created two Advanced Multiaxis Toolpaths, one was a Morph between two curves, the other was Parallel cuts. When I posted and checked that parameter, here was the output:

 

 

 15583    Morph between 2 curves
 15583    Parallel cuts

 

Once you've loaded the string to a user-defined string variable, you can use the "strstr" function to compare the string value in your user-defined string variable to another string to find a match. We can talk about that in an Office Hours class...

Thanks Colin. I'll have a look at this later today. Tweaking this 5 axis stuff is making my brain work, but it is all good

You will also need to rotate the coordinates with the part for TCP

Yeah, well, Okuma Australia were a great help....

Greg, could U be more specific? What does it means?

Thank you in advance!
