DMG CLX450 SIEMENS 840D

[seanGPDQR]

Hi all 

we have a DMG CLX450 with siemens 840d control. We have live tooling but don't have a Y axis all the siemens posts I can find use X and Y for the live tooling is there a post or a way I can get it to use X and C? We have an NLX and on that post I can tell it to utilise C axis and this does just that but there is no option for this on the Siemens post

Does anyone have a working post that will do what I need or is there a way I can change one to suit?

Hi, you could turn off the Y axis in the Siemens Mill/Turn post (https://cam.autodesk.com/hsmposts?p=siemens_mill-turn)...

Line 361, set this to false.

You still may see Y axis in the code, but this will be when Polar Interpolation is active (TRANSMIT), and these will be converted to C axis moves by the controller.  This should eliminate any XY moves being output.

So i have changed what you said and the code posted as the following. As i am a fanuc man and have only programmed the siemens using shop turn could you please advise if it looks correct

i have put the (*) in by the codes i don't have a clue what they are

Also what is the SP= mean cos it wouldn't simulate with that in but if i delete that line it does

[andrew.millardCYPQ9]

Hi,

I'll go through the codes one at a time to give you an explaination of them - 

DIAMOF - turns off Diametral programming (milling is usually radial on these machines).

SETMS - set master spindle - basically what spindle is assigned for the NC code to work on.

TRANSMIT - Polar interpolation

The SP1= function is to set the C axis to a position.  Your machine may need something other than this to work.

You could try editing the code to see if this code works in its place.

Hello Andrew

I have the same problem. I made changes in post processor... but I didn't get good results. I don t want Y in my G code. My CNC don t have Y axis. Can you help me with this crucial problem?

Attach you have the last post process from Fusion library with mill and lathe capabilities... 

Thanks!

All regards, Dan

It will still post with a Y, i can get it to stop however if you have the 'transmit(1)' in before any Y movement the converts the Y to C this is the start and end or a program i use on a CLX450 with no Y i have to change a few things to get it to work on machine but not much the following is after changes and the M17 is because i just insert cad into a shop turn program where needed as a sub program

Hello,

I rezolved with Yaxis and i have a problem.
In the line N21 where the live tooling get the command for spindle and flood i have the error of M.How can i cgange in Post processor for get M1 from M2 wich i have?

Example:
N21 STMS(2)
N22 G97 S2=3600 M2=3
change in
N21 STMS(1)
N22 G97 S1=3600 M1=3

@materialeimportante  Try this post but be very careful it simulates fine on our clx but not run it yet only thing is it wont let me use feed per tooth so have to program with mm/min on all tools
